Note: If, after a braking operation, the „Ready“ LED flashes 2x (braking current
was not reached), it may be possible that the value adjusted for the braking
time was too small (0...1,5s). The braking time is then too short to build up a
flow of current in the motor. If this is the case, turn potentiometer „t“ slightly
clockwise.
11.4 Possible fault indications during commissioning
During commissioning, and in normal operation too, fault indications can occur. The following
explanation is to give you assistance in the localization and correction of faults.

Flashing 2x Adjusted braking
current was not
reached. Interruption in the braking
circuit. Possibly the motor is
started with star-delta
connection. Check circuit. Possibly the star
contactor has to be closed
during braking.
The braking time is adjusted
too short. The braking current
is switched off before the
adjusted value is built up in the
motor winding. Adjust a slightly longer time
with the potentiometer „t“ (turn
slightly clockwise).
The resistance of the motor
winding is too high for the
adjusted braking current Turn braking current back so
that the fault does not occur
any more.
