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.
1. Ensure control power has been isolated and locked out.
2. Disconnect the terminals at the unit.
3. Remove the four M6 bolts per
4. Extract the power supply complete with bracket from the drive.
5. Remove the bracket(s) from the failed power supply (four M4 screws and
nylon shoulder washers).
6. Attach bracket to replacement power supply. Ensure the Black
Insulation(s) is between the AC/DC power supply and the mounting
plate(s).
7. Repeat Steps 5, 4, 3, 2 and 1 in this order to replace the unit.
