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 parallel 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.
