P2.15.3 Brake Frequency limit Closed Loop ID1555
This parameter defines the frequency limit to release the brake.
This value also applies as the maximum frequency reference limit while the brake is
closed. In closed loop control it is recommended to use zero value so that the brake is
released while the drive has zero speed at start. If torque is needed to avoid position
change at the moment the brake mechanically opens use the start-up torque function.
P2.15.4 Closing frequency from forward direction ID1539
Output frequency limit to close the brake when the speed approaches zero speed from
positive direction. Lifting direction must be given as positive frequency.
P2.15.5 Closing frequency from reverse direction ID1540
Output frequency limit to close the brake when the speed approaches zero speed from
positive direction. Lowering direction must be given as negative frequency.
P2.15.6 Brake On/Off Current limit ID1085
If motor current is below this value the brake is closed immediately.
It is recommended to set this value to approximately 25 % of the magnetization current
from the maximum used frequency.
