Internal malfunction
Disconnect motor power cable
from drive and enable drive
with current limit set to 0. If
fault remains, call your A-B
representative. If fault clears,
a wiring error or an error
internal to the motor exists.
35 Soft-Starting Fault
ON indicates a soft fault at
startup. Low AC input voltage
Internal malfunction
Check AC input voltage on all
phases.
Call your A-B representative.
36 Power Module
Overtemperature ON indicates an
overtemperature condition
in the power module. Excessive heat in power
circuitry. Reduce acceleration rates.
Reduce duty cycle (ON/OFF)
of commanded motion.
Increase time permitted for
motion.
Use large Ultra3000 and
motor.
Check motor tuning.
37 AC Input Phase Loss
ON indicates incorrect
power phasing.
Loss of one or more phases of
power.
Check AC input voltage on all
phases.
39 Self-sensing
Commutation Startup
Error ON indicates a self-sensing
commutation error was
encountered during startup
Motion required for self-
sensing startup commutation
was obstructed. Verify that there are no
impediments to motion at
startup, such as hard limits.
Increase self-sensing current if
high friction or load conditions
exist.
Verify the line count, pole
count, or electrical cycle
length motor parameters.
Swap any two motor
connections and verify the
motor feedback counts in the
correct direction during
positive motor movement.
