5. “Ed05” IGBT Overcurrent Error (Sheet 1 of 2)
CHM540S
IGBT Overcurrent error: the drive detects
an overcurrent shunt condition.
Replace motor.
If problem persists, replace inverter control board.
Replace motor.
Yes
Yes
Power down machine for a
minimum of two minutes. Check the
motor phase to phase windings.
Continuity should be uniform
between:
Are windings uniform?
1. L1 and L2 (Black to White)
2. L2 and L3 (White to Red)
3. L1 and L3 (Black to Red)
No
A
Yes
Check the motor phase
to ground checks.
There should be continuity between:
Is there continuity between
phase to ground checks?
1. L1 to ground (Black wire to Green/Yellow wire)
2. L2 to ground (White wire to Green/Yellow wire)
3. Check L3 to ground (Red wire to Green/Yellow wire)
No
Repair or replace bad valve.
No
B
Check the drain and
fill valves. Are they functioning
correctly with no leaks?
