(3) If the motor stalls during acceleration
The motor stalls during
acceleration.
YES
NO
Is the acceleration time
too short?
Prolong the time.
Is the inertia moment of the
motor or the load excessive?
Is a special motor used? Contact GE Drives.
Use a thicker cable between
the drive and the motor or
shorten the cable length.
Has the motor terminal
voltage dropped?
Reduce the inertia moment
of the load or increase the
drive capacity.
Is the torque of the load
excessive?
Reduce the torque of the
load or increase the drive
capacity.
Is the torque boost
set correctly?
Faulty drive or error due
to noise, etc.
Contact GE Drives.
Increase the torque boost.
The motor generates
abnormal heat.
Is the torque boost
excessive?
Reduce the torque boost.
Has the motor been
operating continuously at a
very low speed?
Use a motor exclusive
to the drive.
Is the load excessive?
Reduce the load or increase
motor capacity.
Is the drive output voltage.
Terminals (U, V, W)
balanced?
Faulty motor.
Faulty drive or error
due to noise, etc.

Note: Motor overheating following a
higher frequency setting is likely the
result of the current wave form.
