• Function
These parameters can be used as brake sequences for lifts and similar equipment.
To ensure smooth operation, the motor produces enough torque before the brake is released.

Starting procedure
At the run command, the inverter makes the motor produce the torque specified with parameter . As soon
as a torque output command is issued, a brake release request signal is put out through the brake output terminal.
Upon expiration of the brake release time set with , the motor starts to accelerate.
