13.1.1.3 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
625 has 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.

Flux formation

Field-oriented control in the configurations 2xx and 4xx are based on separate regulation of the flux-
forming and torque-forming current components. Upon startup, the machine is magnetized and a
current is impressed first. With parameter
current I is set. With parameter
sd
time is set.
The current impression is done until the reference value of the rated magnetizing current is reached
