External brake control
The output for controlling the brake is switched 2 ways by a relay. The output
voltage is identical to the input voltage. When selecting the brake, care must
be taken to ensure the appropriate level of voltage endurance.
All the terminals must be fed via the shielded motor connecting cable.
The maximum load for the output is 1 A, and it is not short circuit-proof.
Caution
The converter is equipped with an internal fuse for the brake connection. Short
circuits can trip the internal fuse. If this happens, you have to send the frequency
converter in for repair.
!
Warning
When the parameter for the rated output of the motor is changed, the brake is
temporarily released (for up to 1 second).
What to do:
When you change this parameter, you must ensure that the brake remains applied
(by disconnecting the motor cable, for example).
