Possible cause
Do a check of the loading.
Do a check of the motor.
Do a check of the cables and con-
nections.
Make an identification run.
a sudden heavy load
Set the acceleration time longer
increase
(P3.4.1.2 and P3.4.2.2).
a short circuit in the
motor cables
the motor is not the
correct type
the parameter settings
are not properly made
Set the deceleration time longer
(P3.4.1.3 and P3.4.2.3).
Use the brake chopper or the
brake resistor. They are available
too short a decelera-
as options.

Activate the overvoltage controller.
high overvoltage spikes
Do a check of the input voltage.
in the supply
Do a check of the motor cables and
the motor.
Do a check of the filters.
an insulation malfunc-
tion in the cables or the
motor
a filter (du/dt, sinus)

Reset the fault and restart the
drive.
Do a check of the feedback signal
