Flashing 3x Braking device is
overloaded.
Braking frequency is
too high.
The specified max. braking
frequency is exceeded. Reduce braking current or
braking frequency.
During commissioning,
5 braking operations in
succession can be initiated
without an overload being
indicated.
Flashing 4x
Program- or
controller-error Program- or main-memory of
the controller is defective. If, after several disconnections
from the mains voltage, the
fault is still indicated, return the
device to the producer.
Malfunction
without fault
indication
Braking current
switches off,
although the motor is
still rotating Braking time adjusted too short. Adjust a slightly higher braking
time.
Braking current adjusted to a
too small value. Adjust a slightly higher braking
time.
Motor cannot be
started After a braking interrupt, the
contact on X3-X4 was not
reclosed. Make sure that the contact on
X3-X4 is closed.
When switching the
mains voltage on,
the pre-fuses of the
braking device blow During braking, the power
section ot the braking device
became defective.
Possibly, after a mains reset
caused by overload, the
recovery time of 15 min was not
waited out?
Return the device to the
producer.
Important! Prior to installing a
replacement device, it is
absolutely necessary to check
the contacts of the motor
contactor (contact welding).
During braking, the
pre-fuses of the
braking device blow Fuse rating of pre-fuses is too
low. Select fuse/s in compliance
with the dimensioning rules.
During braking, the power
section ot the braking device
became defective.
Possibly, after a mains reset
caused by overload, the
recovery time of 15 min was not
waited out?
Return the device to the
producer.

Sporadic malfunction, for which there is no comprehensible explanation, may be caused
by an EMC environment largely exceeding the permissible interference levels. The
reason for this may be frequency inverters that are not interference-suppressed or a not
optimal earthing concept.
