Chapter 2: Introduction This Installation Guide is intended for design engineers who are integrating Elmo Motion Control Cymbal servo amplifiers into a machine.

2.1. Product Description The Cymbal series of servo amplifiers is designed to operate in the current mode controlling permanent‐magnet trapezoidal brushless motor and DC brush motor.

The Cymbal exhibits “the highest density of power and intelligence” and can deliver up to 11.3 kW of continuous power or 13.6 kW of peak power in a most compact and efficient package.

The Cymbal operates from a DC power source in the range from 12 to 195 VDC.

The Power stage of the Cymbal is fully isolated from other sections of the Cymbal, such as the control stage and the heatsink. This contributes very significantly to the safety and the EMI immunity of the Cymbal. In addition it simplifies the requirements of the DC power supply used to power the DC bus of the Cymbal and allows also the operation with a non‐isolated DC power source. The Cymbal incorporates full custom mixed analog/digital ICs and a hybrid power stage. The basic configuration is a current mode amplifier targeting the OEM market. As such, no trimmers are used in the basic version. In addition to its compliance with relevant MIL standards, the Cymbal amplifier also meets UL 508C and the relevant CE regulations.

The Cymbal power stage is implemented on ceramic substrates. This design enables very high thermal conductivity, high current carrying capacity, improved EMC and good mechanical strength. The control section is implemented by dedicated custom ICs that contribute to enhanced performance and reliability.

2.2. Standard Features • Operates in current mode

• Internal DC‐to‐DC converter, which allows for operation from a single supply

• Zero dead‐band

• Excellent linearity

• One differential input

• Motor current monitor

• Current gain change for low inductance motors

• Remote current gain control

• Status indication and remote control functions by four open collector transistors

• External continuous and peak current‐limit adjustments

• Package: plated‐aluminum base plate, plastic housing, UL 94V0 recognized

• Ultra‐lightweight of 700 grams (24.7 oz)

2.3. Fault Protection Built‐in protection against possible fault conditions, including:

• Shorts between the outputs or between each output and the power input/return

• Overheating

• Undervoltage/overvoltage

• Failure of internal power supplies

• Latch mode for each protective feature

2.4. How to Use this Guide Installation is the first step in integrating and operating the Elmo Cymbal servo amplifiers. After carefully reading the safety instructions in the first chapter, the following chapters provide you with installation instructions as follows:

• Chapter 3, Installation, provides step‐by‐step instructions for unpacking, mounting and connecting the Cymbal.

• Chapter 4, Servo Control Operation, explains how to control the operation of the servo amplifier.

• Chapter 5, Technical Specifications, lists all the drive ratings and specifications.

Chapter 3: Installation

3.1. Before You Begin

3.1.1. Site Requirements You can guarantee the safe operation of the Cymbal by ensuring that they are installed in an appropriate environment.

Feature Value

Ambient operating temperature 0 °C to 50 °C (32 °F to 122 °F)

Maximum non‐condensing humidity 90%

Operating area atmosphere No flammable gases or vapors permitted in area

Note: Models for extended environmental conditions are available.

Caution: The Cymbal dissipates its heat by convection. The maximum ambient

operating temperature of 0 °C to 50 °C (32 °F to 122 °F) must not be exceeded.

3.2. Unpacking the Amplifier To unpack the Cymbal:

1. Carefully remove the servo amplifier from the box and the Styrofoam.

2. Check the amplifier to ensure that there is no visible damage to the instrument. If any damage has occurred, report immediately to the carrier that delivered your amplifier.

3. To ensure that the Cymbal you have unpacked is the appropriate type for your requirements, find the part number sticker on the side of the product:

The P/N gives the type designation as follows:

4. Verify that the Cymbal type is the one that you ordered, and ensure that the voltage meets your specific requirements.

3.3. Mounting the Cymbal The Cymbal has been designed for Wall Mount along the back (it can also be mounted horizontally on a metal surface)

M5 socket head cap screws, one through each opening in the heatsink, are used to mount the Cymbal (see the diagram below).

For full power output capability the Cymbal is designed to be mounted on an external heatsink. It is highly recommended that the wall on which the Cymbal is mounted will have heat dissipation capabilities. The Cymbal at “free air convection” (without an additional heatsink) can dissipate around 12 W to 15 W.

Figure 1: Mounting the Cymbal

3.4. Connecting the Cables

3.4.1. Wiring the Cymbal Once the Cymbal is mounted, you are ready to wire the device. Proper wiring, grounding and shielding are essential for ensuring safe, immune and optimal servo performance of the Cymbal.

Caution: Follow these instructions to ensure safe and proper wiring:

• Use twisted pair shielded cables for control, feedback and communication connections. For best results, the cable should have an aluminum foil shield covered by copper braid, and should contain a drain wire.

The drain wire is a non‐insulated wire that is in contact with parts of the cable, usually the shield. It is used to terminate the shield and as a grounding connection.

• The impedance of the wire must be as low as possible. The size of the wire must be thicker than actually required by the carrying current. A 24, 26 or 28 AWG wire for control and feedback cables is satisfactory although 24 AWG is recommended.

• Use shielded wires for motor connections as well. If the wires are long, ensure that the capacitance between the wires is not too high: C < 30 nF is satisfactory for most applications.

• Keep all wires and cables as short as possible.

• Keep the motor wires as far away as possible from the feedback, control and communication cables.

• Ensure that in normal operating conditions, the shielded wires and drain carry no current. The only time these conductors carry current is under abnormal conditions, when electrical equipment has become a potential shock or fire hazard while conducting external EMI interferences directly to ground, in order to prevent them from affecting the drive. Failing to meet this requirement can result in drive/controller/host failure.

• After completing the wiring, carefully inspect all wires to ensure tightness, good solder joints and general safety.

3.5.1.1. Connecting the Motor Cable

Connect the motor power cable to the M1, M2, and M3 terminals of the main power connector and the fourth wire to the PE (Protective Earth) on the heatsink (see diagram above).

Notes for connecting the motor cables:

• For best immunity, it is highly recommended to use a shielded (not twisted) cable for the motor connection. A 4‐wire shielded cable should be used. The gauge is determined by the actual current consumption of the motor.

• Connect the shield of the cable to the closest ground connection at the motor end.

• Connect the shield of the cable to the PE terminal on the heatsink.

• Be sure that the motor chassis is properly grounded.

• To close the motor cable into the drive, use the barrel connector, M6 spring washer and M6 nut (in the drive). The required torque is 3 to 4 Nm.

• To close the PE wire into the drive, use the barrel connector, M5 flat washer, M5 spring washer and M5 screw to the heatsink. The required torque is 3 to 4 Nm.

• Use flex wire 6/8/10 AWG to barrel connector.

Figure 4: AC Motor Power Connection Diagram

3.5.1.2. Connecting the DC Power

The Power stage of the Cymbal is fully isolated from other sections of the Cymbal, such as the control stage and the heatsink. This contributes very significantly to the safety and the EMI immunity of the Cymbal. In addition it simplifies the requirements of the DC power supply used to power the DC bus of the Cymbal and allows also the operation with a non‐isolated DC power source.

3.5.1.2.a Operation with an Isolated DC power Supply

The PE (Protective Ground of the AC network) is connected to the VN‐ terminal (the Negative Power Input terminal).

www.elmomc.com


20

Figure 5: Isolated DC Power Supply

In this case the isolation is achieved by the isolation transformer.

It is highly recommended to connect the network PE to the Return (negative terminal) of the Power Supply.

Figure 6: Isolated Power Supply

In this case the isolation is achieved by using a battery.

It is highly recommended to connect the PE to the Return (negative terminal) of the Power Supply.

3.5.1.2.b Operation with a Non‐Isolated DC power Supply:

The PE (Protective Ground of the AC network) must not be connected to the Negative Power Input (the VN‐ terminal) of the Cymbal.

www.elmomc.com


21

Figure 7: Non‐Isolated DC Power Supply

The Power Supply is directly connected to the AC line (The AC must be limited to 135 VAC not to exceed the max 190 VDC in case of 200 VDC drive).

The network PE must not be connected to the Return of the Power Supply.

Figure 8: Non‐Isolated DC Power Supply

The Power Supply is directly connected to the AC line through an Autotransformer.

The network PE must not be connected to the Return of the Power Supply.

Caution: Connecting the PE to the VN‐ with a non‐ isolated power supply will cause damages to the system (Any component that is connected to the system might be damaged).

www.elmomc.com


22

Notes for connecting the DC power supply:

• Be aware: The Cymbal can operate from either an:

isolated DC power supply or

non‐isolated DC power supply

• For best immunity, it is highly recommended to use twisted cables for the DC power supply cable. A 3‐wire shielded cable should be used. The gauge is determined by the actual current consumption of the motor.

• Connect both ends of the cable shield to the closest ground connection, one end near the power supply and the other end to the PE terminal on the Cymbal’s heatsink.

• For safety reasons connect the VN‐ of the power supply to the closest ground connection.

• To close the power supply cable into the drive, use the barrel connector, M6 spring washer and M6 nut (in the drive). The required torque is 3 to 4 Nm.

• To close the PE wire into the drive, use the barrel connector, M5 flat washer, M5 spring washer and M5 screw to the heatsink. The required torque is 3 to 4 Nm.

3.5.1.3. Connecting the Optional Backup Supply Cable

Power to the Cymbal is provided by a 12 to 195 VDC source (depending on model type). A “smart” control‐supply algorithm enables the Cymbal to operate with the power supply only, with no need for an auxiliary supply voltage. If backup functionality is required for storing control parameters in case of power‐outs, an external 12 to 195 VDC power supply can be connected, providing maximum flexibility and optional backup functionality when needed.

Note: In the 400 V product line (CYM xx/400), there is no internal connection to enable the

main input to power the internal SMPS for low logic voltages. Therefore, a 24 VDC auxiliary power supply must be connected in order to activate the 400 V drive’s internal SMPS. For the xx/400 model, the 24 VDC auxiliary power supply can also carry out the backup functionality described above.

To connect the backup supply to the Auxiliary port, use the Cymbal's J1 connector (Back up supply connector). Remember, you are working with DC power so be sure to exercise caution.

Notes for backup supply connections:

• Use a 24 AWG twisted pair shielded cable. The shield should have copper braid.

• The source of the backup supply must be isolated.

• For safety reasons, connect the return of the backup supply source to the closest ground.

• Connect the cable shield to the closest ground near the power source.

• Before applying power, first verify the polarity of the connection.

3.5.2. Control, I/Os and Halls Cable Assemblies The Cymbal features easy‐to‐use D‐Sub type connections for all Control, I/Os and halls cables. Below are instructions and diagrams describing how to assemble these cables.

• Use 24, 26 or 28 AWG twisted‐pair shielded cables (24 AWG cable is recommended). For best results, the shield should have aluminum foil covered by copper braid.

• Use only a D‐Sub connector with a metal housing.

• Attach the braid shield tightly to the metal housing of the D‐type connector.

• On the motor side connections, ground the shield to the motor chassis.

• On controller side connections, follow the controller manufacturer’s recommendations concerning the shield.

3.6. DC Power Supply The DC power supply can be at any voltage in the range defined in the technical specifications (Chapter 5 of this guide). The supply source must comply with the safety aspects of the relevant requirements, in accordance with the most recent version of the standard EN60950 or equivalent Low Voltage Directive Standard, all according to the applicable over‐voltage category. If the power source to the power supply is the AC line (through an isolated or a non‐isolated transformer), safety margins must be considered, in order to avoid activating the undervoltage/overvoltage protection due to line variations and/or voltage drop under load.

In addition to the above, the transformer must comply with the safety aspects of the relevant requirements in accordance with the most recent version of the standard EN 60742 (Isolating and Safety Isolating Transformers). The nominal DC bus voltage should be in the following range:

1.2 Vdcmin < Vdc < 0.9 Vdcmax

Where: Vdcmin is the minimum DC bus

Vdcmax is the maximum DC bus

The transformer power should be calculated such that it will be able to deliver power to the amplifier (including peak power) without significant voltage drops.

The power supply should be located as close as possible to the amplifier. While driving high‐inertia loads, the power supply must be equipped with a shunt regulator; otherwise, the amplifier will be disabled whenever the capacitors are charged above the maximum voltage, during motor break down.

3.6.1. Powering Up After the Cymbal is connected to its devices, the Cymbal is ready to be powered up.

Caution: Before applying power, ensure that the DC supply is within the specified range and that the proper plus‐minus connections are in order.

3.6.2. Initializing the System After the Cymbal has been connected and mounted, the system must be set up and initialized.

3.7. Heat Dissipation For full power output capability the Cymbal is designed to be mounted on an external heatsink. It is highly recommended that the “Wall” on which the Cymbal is mounted will have heat dissipation capabilities. The Cymbal at “free air convection” (without an additional heatsink)

can dissipate around 12 W for 40 °C ambient temperature and not exceeding 80 °C on the heatsink.

When “Free Air Convection” is sufficient for the application it is recommended to leave approximately 10 mm of space between the Cymbal's heatsink and any other assembly.

3.7.1. Cymbal Thermal Data

• Free air convection thermal resistance (θ): Approximately 3.6 to 4 °C/W.

• Thermal time constant: Approximately 40 minutes/ 2400 seconds (thermal time constant means that the Cymbal will reach 2/3 of its final temperature after 4 minutes).

• Self heat dissipation capability (no external heatsink): 12 W for 40 °C/W temperature rise.

• Shut‐off temperature: 86 °C to 88 °C (measured on the heatsink).

• The thermal resistance when connecting to an external heat sink:

The surface of the external heatsink is 50 μm: 0.18 °C/W. Thermal conductive compound. By proper Smearing of the surface a significant

improvement of the thermal resistance is achieved: 0.13 °C/W

3.7.3. How to Use the Charts The charts above are based upon theoretical worst‐case conditions. Actual test results show 30% to 50% better power dissipation.

To determine if your application needs a heatsink:

1. Allow maximum heatsink temperature to be 80°C or less (shunt down is 6 °C to 8 °C higher).

2. Determine the ambient operating temperature of the Cymbal as ≤ 40 °C.

3. Calculate the allowable temperature increase as follows:

For an ambient temperature of 40°C, ΔT= 80 °C – 40 °C = 40 °C

4. Use the chart to find the actual dissipation power of the drive. Follow the voltage curve to the desired output current and then find the dissipated power.

5. If the dissipated power is below 12 W the Cymbal needs no additional cooling.

Note: The chart above shows that no heatsink is needed when the heatsink temperature is

80 °C, ambient temperature is 40 °C and heat dissipated is 4 W.

Chapter 4: Servo Control Operation

4.1. Cymbal Connected to DC Motors In order to connect the Cymbal to a DC motor, connect Hall A (J4 pin 5 of the drive to Hall return (J4 pin 3 of the drive). The motor should be connected to M2, M3.

4.2. Current Command Input The Cymbal has a single differential input. The input operating voltage range is ±10 V, meaning that a 10 V signal will result in a fully rated peak current. The current limit circuits will override this signal if the peak duration exceeds 2.7 seconds and/or the required current exceeds the values set by the ECLC and ECLP signals. If the input command voltage exceeds 10 V, input scaling must be implemented by adding a pair of external resistors, according to the following formula:

Rin (KΩ) = (5.33 * Vin) – 53.6

Be careful not to apply input voltage above the maximum allowed input voltage as this will cause the input operational amplifier to operate beyond its limits (±20 V) and in extreme cases, may even damage it.

4.3. External Current Limit - Continuous (ECLC) The continuous current limit of the Cymbal amplifiers can be scaled down by an external voltage or by an external resistor connected from pin J2/13 (ECLC) to pin J2/8 (ECLRET).

4.3.1. External Voltage

VECLCIC(new) =

3.75V* Ic(nom)

VECLCIC(new) =

3.75V* Ic(nom)

An external positive voltage (0 to 3.75 V) to terminal J2/13 (ECLC) in reference to terminal J2/8 (ECLRET) will control the continuous current limit from zero to Ic (nom).

The voltage is internally clamped to 3.75 V whenever the external VECLC is greater than 3.75 V.

The external voltage source must be able to source/ sink at least ±0.2 mA.

The maximum absolute VECLC allowed to be connected is 5 V.

4.3.2. External Resistor Connect an external resistor between terminal J2/13 (ECLC) and terminal J2/8 (ECLRET).

The resistor value is given by:

(Kohm) = 37.4 * Ic(new)

Ic(nom)- 1RECLC (Kohm) = 37.4 * (Kohm) = 37.4 *

Ic(new)

Ic(nom)- 1RECLC RECLC

0 < RECLC < 36.4 K (1/8 Watt)

At RECLC greater than 36.4 K, the current limit will be internally clamped to the nominal value. Ic (nom) is the nominal continuous current limit of the amplifier.

4.3.3. External Current Limit Peak (ECLP) The peak current limit of the Cymbal amplifiers can be scaled down by an external voltage or by an external resistor connected between pin J2/12 (ECLP) and J2/7 (ECLRET).

4.3.4. External Voltage An external positive voltage (0 to 3.75 V) to terminal J2/12 (ECLP) in reference to terminal J2/7 (ECLRET) will control the peak current limit from zero to Ip(nom).

VECLPIp(new) =

3.75V* Ip(nom)

VECLPIp(new) =

3.75V* Ip(nom)

The voltage is internally clamped to 3.75 V whenever the external VECLP is higher than 3.75 V. The external voltage source must be able to source/sink at least ±0.2 mA. The maximum absolute VECLP allowed to be connected is 5 V.

(Kohm) = 37.4 * RECLP Ip(new)

Ip(nom)- 1(Kohm) = 37.4 * RECLP (Kohm) = 37.4 * RECLP

Ip(new)

Ip(nom)- 1

4.3.5. External Resistor Connect an external resistor between terminal J2/12 (ECLP) and terminal J2/7(ECLRET). The resistor value is given by:

0 < RECLP < 36.4 K (1/8 Watt)

At RECLP greater than 36.4 K, the current limit will be internally clamped to the nominal value. Ip(nom) is the nominal peak current limit of the amplifier.

4.3.6. Latch Mode (LM) By connecting J2/5 to J2/10, the amplifier is latched to disable mode whenever a Short, Commutation or Over Temperature failure occurs. Disabling the amplifier temporarily by removing the power from Enable pin J2/14 resets the latch. Be sure to restore the Enable connection when the reason for the event no longer exists.

Table 10: Cymbal Status Indications

Notes:

• Without latch mode: The status indications are reset when the fault disappears.

• With latch mode: The Short, Over Temperature and Commutation Failure status indications are reset when the enable signal is temporarily removed from the enable input.

• Multiple faults: Only the reading of the first fault is reliable. Additional faults add on to the status outputs and the indication is therefore meaningless.
