7.5.29.3 Setting controller inhibit
Purpose
Controller inhibit can be set e.g. in case of a fault (LU, OU, …).
Function
When the controller is inhibited (CINH) the BRK-OUT signal is immediately set to HIGH. The drive is
then braked via the mechanical brake.
If the fault is eliminated quickly, i.e. the controller inhibit (CINH) is reset before the actual falls below
the threshold value BRK-Nx, the BRK-OUT signal is set immediately to LOW. The drive is
synchronised to the actual speed and follows its setpoint.
If the value falls below the threshold, the drive starts as described under ”Opening the brake”.
