Holding brake control
8.12.6 Torque precontrol during starting
The motor is precontrolled by selecting the lower speed threshold for applying the brake.
When the upper speed threshold for brake release is reached, the motor is precontrolled for
200 ms with the lower threshold before the brake switches to the release mode.
If the servo control (SC) operating mode has been selected, an additive torque value in
[%] can be selected via the nBrkTorqueAdd_a input.
The direction of the precontrol value can be inverted by setting bit 2 under C02582
.
If bit 3 is set to "0" (hoist application) in C02582
, a quadrant-related feedforward
control method (feedforward control in motor mode and operation in generator mode
during lowering) will be used.
