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,
re-connect the power supply to the circuit and re-measure the output. Adjust
if necessary.
If it is not possible to maintain 56 V DC, the power supply may be faulty.
