Output Calibration
Ensure the output of the supply is 56V DC.
There is a potentiometer on the top of the power supply that adjusts the 56 Volt
DC output for the power supply. Isolate the output of the power supplies;
multiple supplies in series will affect your measurements. With the control power
on and the output of the AC/DC Converter isolated from the drive control,
adjust the potentiometer until the output equals 56 volts DC. Perform this test
on each power supply. When all adjustments are complete, reconnect the power
supply to the circuit and re-measure the output. Readjust if necessary.
If it is not possible to maintain 56 V DC, the power supply may be faulty.
