• Power feedback and storage

• Speed, position and torque control with excellent andresponsive control characteristics

• Throttle-free coupling and energy transmission from as manyindependently working motor or generator driven machinesas required, to a common supply line with quasi-constantoperating pressure

Secondary unit Type A4VSO250DS1 Control and monitoring electronics VT 12000 withfrequency/voltage converter VTS 0102

Functional descriptionSecondary controlled hydrostatic machines connected to apower network with quasi-constant operating pressure meanhigh response, energy saving drives for speed, position andtorque control with power feedback.

No throttling is required for either power take up or feedback, thedisplacement of the machine adjusting itself to the relevantloading. This means that any number of units, operating asmotors or pumps, may be connected in parallel. Four quadrant

operation is even possible in open loop operation, the units usedfor speed and torque reversal being swivelled over the "Zero".This also reverses the direction of flow .

If required an accumulator may be fitted between the primaryand secondary units.

This accumulator is used to cover rapid flow peaks and also tostore energy returned by pump from the secondary unit to thehydraulic circuit, where this energy is not required by any otheractuators. The pre-load pressure and loading condition of theaccumulator, together with the pressure compensated primaryunit and degree of loading on the secondary unit, determine thequasi-constant high pressure in the system.

The specific characteristics of secondary control such as reducingthe amount of equipment required in primary control, combinedwith the possibility of power feedback, the storage of brakingenergy and virtually load-independent speed and positioningaccuracy, open up a wide range of applications.

For further information see "Hydraulic Trainer Vol. 6"(RE 00 293).

Component parts of a secondary unit

The DS1 speed controller is used to control the swivel angle anddisplacement of a secondary unit at quasi-constant operatingpressure so that the correct torque is made available to maintainthe required speed.In a quasi-constant pressure system the torque is proportionalto the swivel angle or displacement of the axial piston unit. Theswivel angle is fed back by means of an inductive positionaltransducer and the rotational speed by means of a tacho-generator.The unit is supplied complete with a servo valve and flushingplate. Please note the commissioning instructions in RE 07 700and RE 29 586. For less demanding applications the servo valvemay be replaced by a proportional valve.

The control and monitoring electronics VT12000 to RE 29 775and the frequency/voltage converter and monitoring electronicsto RE 29 761 are not included. The system is electronicallyprotected against excessive speeds.

Speed controller DS1

Pilot operated check valve RVE (hydraulic isolator), mounted onthe high pressure port, is returned to the closed position in theevent of an emergency. The secondary unit is then separatedfrom the pressure line to effect braking with power feedback.

In order to prevent cavitation due to the motor running on (orbackwards) during an emergency stop, anti-cavitation valvesmust be used and mounted onto port B1. These valves, checkvalves without spring, must be mounted vertically and are to beordered separately.

Technical data: Torque controller card MD 1, RE 29 797

The MD 1 torque controller card is used in conjunction with theVT 12000 amplifier for secondary control drives (see RE 29 775).It makes possible the mainentance of a pre-set torque in open orclosed loop operation as well as calculation of the torque for thesecondary unit and its output as an analogue voltage.

Characteristics:

– Analogue pre-setting of the command value by way ofdifferential inputs for voltages of 0 to ± 10 V or currents of 0 to± 20 mA or 4 to 20 mA.

– Analogue signal output for calculated torque

– PID torque regulator, optionally as disturbance variableregulator

– Analogue pressure compensation for correcting performancecurves taking into account actual pressure value

– Loss compensation through internal pressure compensationor by means of an externally pre-set correction value

– Internal speed limiting when used with VT 12000

– May be connected to a PLC via opto-decoupled and short-circuit protected inputs and outputs

– DIL switch for implementing various types of circuit
