The cursor is then located on the polarity of either Input. Use the UP/DOWN arrows to position the cursor on the desired input to be changed. Use the LEFT/RIGHT arrows to toggle the polarity to "+" and "-". Once the desired polarity is shown, enter a carriage return to enter the polarity.

System Calibration

The System Calibration feature allows you to setup the calibration and loop gain of the 520 PMC/external drive combination to maximize system performance. Enter the Calibrate Velocity (maximum drive velocity) and the Calibrate Velocity Command Voltage (command voltage required to produce maximum velocity). With these two parametersyou, the 520 PMC calculates the proper command voltage needed to produce the desired motion profile. The Encoder Lines Per Revolution is currently fixed at 1024.

You can jog the motor at various velocities through the Calibrate Jog Velocity selection. By monitoring the Following Error when jogging at various velocities, you can "fine tune" the system so a perfect match between the 520 and the external drive is achieved. "Fine tuning" may consist of slightly altering the Calibrate Velocity or Calibrate Velocity Command Voltage on the 520 or by altering the command scaling or the offset adjustments on the external drive.

In addition, pre-programmed indexes may be executed to allow monitoring and adjustment of Position Loop Gain. Position Loop Gain should be set as low as possible to permit satisfactory operation while not creating an instability in the system. In some circumstances, modification of the external drive may be required to allow for proper operation.

Lastly, the Position Loop Gain Adjustment Range is setup. This parameter limits the amount of Loop Gain adjustment from the UP/DOWN switch located on the front of the 520 PMC. By setting this parameter to 0%, the UP/DOWN switch has no effect on Position Loop Gain. By setting this parameter to 100%, the UP/DOWN switch has full Position Loop Gain adjustment capabilities.
