12.2 Digital readout error codes (Variable speed models)
Message Possible Cause Correction *
OCL Internal electronic overload has been tripped.
Do not overload motor; reduce pressure of
workpiece against wheels.
OH IGBT protection activated.
Inspect wire connections to U/V/W for possible
short circuits. Verify that motor rating
corresponds to AC motor drive output power.
OE
Excessive input voltage (exceeds AC driver
limits).
Use correct voltage.
LE1
Low voltage; AC motor driver detects that DC
bus voltage has fallen below minimum
threshold Make sure input voltage falls within range of AC
motor input voltage range. Check for abnormal
load in motor.
LP1 Low input voltage (below AC driver limits) Use correct voltage.
