1 Publication 1756-RN681A-EN-P - August 2010 ControlLogix Drive Module (v2.05) (Cat. No. 1756-DMD30) These release notes correspond to major revision 2, minor revision 5 of the SD3000 Interface (1756-DMD30) firmware. Use this firmware release with: Software Product: Compatible Version: RSLogix 5000 programming software 8.02.00 or later RSLinx software 2.30 or later RSNetWorx for ControlNet software 3.00 or later DriveExecutive programming software 1.01 or later
Changes Alternator Power Selection, P168 [Drive I/O Ctrl], B14 “AltrnatorPwr”
For cases where alternator power is used instead of utility power, this option has been added to allow the drive to better track the AC Line Frequency. The trade off is that the line frequency filtering is reduced when the Alternator Power option is selected.
The program defaults to selecting “Alternator Power,” to provide the best frequency tracking, whether connected to the Utility power or Alternator power. It is recommended to have “Alternator Power” selected.
The standard ControlLogix application software is being updated to link this parameter to the ControlLogix program with a default of “Alternator Power” being selected.
Note: The Field must be turned off when changing the state of this bit, otherwise the Field Power Module fuses will clear during the (Bit 14) setting or resetting process.
V2.05 Processor Memory Capacity Issue
When the PMI Rack is used for motor control, the O-60021-x PMI Processor must be used.
The O-60000-x processor lacks sufficient memory to load the Operating System.

Parameter 308 [Output Current] Scaling Corrected
Lgx00036565Parameter 308 [Output Current] has a scaling bug that causes the value to read low by a factor of 10. This is a result of the way the PMI OS scales hidden parameter 2128 [Arm Amps Fdbk]. P2128 [Arm Amps Fdbk] is scaled in amps rather than amps x 10 if P2182 [Motor NP FLA] x (P2184 [PMI Curr Lim] + 75%) is greater than 3000 amps.
Below are examples that illustrate how the scaling works.
Case 1, Lim=100, Solution to Equation, Less than 3000, V2.5_OS17_Bld_08, by_TGM_05_14_10I_burden = .264 A
P321, P324, and P327 bit 26/27 descriptions have been changed from “Drv Fault” and “Drv Warning” to “MC Fault” and “MC Warning”.
Fiber Optic Loop Back for Drive Module
Lgx00054159
To run the loop back test.
1. Select parameter 168 [Drive I/O Ctrl].
2. On the Link Source tab and choose “No Link”.
3. On the Value tab, select Bit 15 “DM Fiber Tst”.
4. Click OK.
To return to normal operation.
1. On the Value tab, deselect Bit 15 “DM Fiber Tst”.
2. On the Link Source tab and type 168 in the Find Parameter field.
3. Select (P 628 Integer In 14) in the list.
4. Click OK.
Parameter 129 [Atune Torq Ref] Minimum Value
Lgx00036999
The default value for parameter 129 [Atune Torq Ref] is 0.5. Down-loading a .dno file with parameter 129 set to 0.5 results in a “readback error”. If the .dno file is saved, parameter 129 is set to zero. Subsequent downloads result in a “out-of-range error”.
The parameter file was updated to change the minimum value of parameter 2203 [Out Volt Rating] from 1V to 10V.

Add Parameter 309 [Selected Trq Ref]
Lgx00059313
Added parameter 309 [Selected Trq Ref]
This parameter is required as a reference to torque helpers in multi-drive sections.
Note: The selection is made in P110. [Spd/Trq ModeSel]
P17 [Jog Speed 1] and P18 [Jog Speed 2] Not Retained During Power-Down
Lgx00036330
Parameters 17 [Jog Speed 1] and 18 [Jog Speed 2] were not retained during a power down. This has been corrected.
Setting P2154 [FML Crossover Freq] to Zero Causes PMI Comm Loss
Lgx00038494
When parameter 2154 [FML Crossovr Freq] is set to zero, parameter 2122 [MC FAults], bit 15 “PMI CommLoss” is set true and the PMI processor OK light extinguishes. Power cycling the PMI rack is required to reset faults.
This has been corrected.

Parameters Added in v2.001 Now Added to Parameter Groups
Lgx00034855
Parameters introduced in revision 2.001 were added to parameter groups.
The following parameters were added in firmware revision 2.001 but were not included in parameter groups. This has been corrected. The File and Group to which the parameters have been added are identified in the table below:
Parameter 304 [Limit Status] Bit Names Changed
Lgx00044343
Parameter 304 [Limit Status], bit 4, 9, 20, and 25 are now described as current limits (CLim) not power limits:
• P304, B4 - “P120 CLim +”
• P304, B9 - “P2184 CLim +”
• P304, B20 - “P119 CLim -”
• P304, B25 - “P2184 CLim -”

Incorporate the CCT (Continuous Current Threshold) Bit
P169 [Drive I/O Status], B10 “Ccz Thresh” is set when the motor control algorithm has determined that the system is in continuous conduction.
NVS Parameter Update, Parameters 664 and 2210
Parameter 664 [Lgx Comm Format] was NVS backed but should not have been. This has been corrected.
Parameter 2210 [Tick Per Scan] was not NVS backed and it should be, this has been corrected.

Field Power Module, Default to S2R (4 Quad) to Avoid Clearing FusesThe only field power modules for sale by Drive Systems are the S2R. If an S2R (4 Quadrant) Field Power Module is physically installed and S2 (non-regenerative, 2 Quadrant) Field Power Module is selected, the fuses will clear.
The program has been changed to default to the S2R (4 Quadrant) Field Power Module. The various power code configurations are shown below. In each case the S2R (4 Quadrant) Field Power Module is the default.

Torque/Current Limits Not Separately Adjustable
Lgx00053819
When the VPL Current Limit or the PMI Current Limit is reached, the Speed Loop PI (Integral Part) is held from moving in the direction of Limit. When parameter 153 [Control Options], B15 “Invt Mtr Cur” is set, the Speed Loop PI Integral Hold function is reversed.
Bumpless Transfer
Lgx00049873
Prior to v2.05, the presetting of the Integral occurred in the following manner:
• On a transition from Torque Control (P110 equals “2”, “3” or “4”) to Speed Control (P110 is equal to “1”) the Integral part is preset to Torque_Reference – (Kp * Error).
Where: Torque_Reference = P303
Change made in V2.05:
• On a transition from Torque Control (P110 equals “2”, “3” or “4”) to Speed Control (P110 equals “1”) the Integral part is preset to Selected Torque_Reference.
Where: Torque_Reference = P309
Resolver Rollover, When Resolver Feedback Not Selected
This was showing up as spikes in the resolver data sawtooth waveform when resolver feedback is not selected for feedback, but is used for monitoring purposes.
The set-up shown below provides an example where Motor Voltage is used as the feedback and the Resolver Feedback is monitored.

The trace is “clean” no signs of rollover problem.
CT, Imbalance Detection Too Low
Lgx00070679
The CT Imbalance Detection Threshold was increased from 3% to 25% due to nuisance “CT Reversed” Warnings. In addition there was an error found in the original calculation equation.

P354 Curr Rate Limit Minimum Value
Lgx00065311
The minimum value of Parameter 354 [Curr Rate Limit] has been changed from 10.0 [PU/sec] to 0.1[PU/sec].
P327, B27 “Drv Warning” Set after P2123 [MC Warning] is Cleared with P166, B19
Lgx00078417
Parameter 327 [Alarm Status 2], bit 27 “Drv Warning” should only be set when a bit in parameter 2123 [MC Warnings] is set.
If P2123 is cleared by setting parameter 166 [Motor Ctrl Cmmd], bit 19 “Clr Drv Wrn”, P2123 is cleared, however, parameter 327, bit 27 was not being cleared. This has been corrected.
Field Economy Counter Preset
Lgx00070729
It appeared that FieldOffDelayCounter was not being properly preset on power-up, after flash, or after DNO load. It appears that FieldOffDelayCounter would hold a large negative value and only reaches the FieldOffDelayCounts after a long time. Placing the drive in run briefly and stopping, sets FieldOffDelayCounter to zero and would restore proper field economy operation.
This has been corrected and the counter is preset properly.
1756-DMD30 P2150 thru P2163 cannot be linked
Lgx00095604
Corrected linking function for parameters 2150, P2153, P2154, P2157, P2158, P2159, P2160, P2161, P2162, P2163 and retain read/write attribute (green in DriveExec).
Disabled linking for parameters 2151, P2152, P2155, and P2156 and change to “read only in run” (black in DriveExec).
