Motor damage caused by overheating
The motor can overheat if it is braked for long periods of time or frequently using DC
braking. This may damage the motor.
• Monitor the motor temperature.
• If the motor gets too hot during operation you must select another braking method or
give the motor more time to cool down.
With DC braking, the inverter outputs an internal OFF2 command for the time that it takes to
de-energize the motor p0347 - and then impresses the braking current for the duration of the
DC braking.
The DC-braking function is possible only for induction motors.
DC braking when falling below a start speed
Precondition: p1230 = 1 and p1231 = 14
DC braking when a fault occurs
Precondition: Fault number and fault response
are assigned using p2100 and p2101
DC braking initiated using a control command
Precondition: p1231 = 4 and p1230 = control
command, e.g. p1230 = 722.3 (control command
via DI 3)
DC braking when switching off the motor
Precondition: p1231 = 5 or p1230 = 1 and p1231
= 14
