Output Calibration
Ensure the output of the supply is 56V DC
(a)
.
There is a potentiometer on the top of the power supply that adjusts the
56V DC
(1)
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 56V DC
(1)
. 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 56V DC
(1)
, the power supply may be faulty.
