625 Brake release time
In order to protect the motor holding brake against damage, the motor may only start after the brake
has been released. Startup to reference speed is effected only after the
elapsed. The time should be set such that it is at least as long as the time required for releasing the
holding brake. By using negative values for the parameter, release of the brake is delayed. This can
be done in order to prevent loads from falling down, for example.
