4.1.2 Torque Mode - Setup
The factory preset potentiometer settings are adjusted for the torque mode operation.
To set up and run the DynaDrive 1525-BRS in the torque mode, perform the following:
1. Turn power off.
2. Remove J1.
3. Check all wiring connections. Verify that J3 jumper is installed.
4. Set the RMS, PEAK CURRENT LIMIT and SIGNAL pots to match the motor as
indicated in Table 2. For preliminary testing under no load, use the factory preset pot
settings.
5. Check that the TACHOMETER pot is full counterclockwise (CCW).
6. Check that the COMPENSATION pot is full clockwise (CW).
7. Replace J1.
8. Inhibit the DynaDrive by pulling pin 8 of J1 to common.
9. Turn power on.
10. Insure that the voltage at COMMAND + and COMMAND – is zero.
11. Enable the DynaDrive by removing the inhibit of step 8.
12. The green LED should be the only LED on. No other LEDs should be on at this point. If
any other situation exists, check the TROUBLESHOOTING section of this manual.
13. Adjust the BALANCE pot to give zero volts at CURRENT MONITOR OUT, J1 pin 9.
14. Apply a voltage (0 to +/- 10 VDC) at COMMAND + and COMMAND -. The motor
shaft should turn CW when COMMAND + is positive and should turn CCW when
COMMAND + is negative. At low COMMAND voltage, holding the shaft can stall the
motor. At higher COMMAND voltage, the torque is much greater and it should be
difficult to stall the motor.
