Note
If an actual speed larger than the value at BRK-Nx is detected before the brake-open time (C0196)
has elapsed, the BRK-QSP and BRK-M-STORE signals are immediately reset. The drive can
immediately operate speed- or phase controlled. If the BRK-QSP output acts on the QSP control
word, the drive synchronizes to the actual speed and follows its setpoint.

7.6.12.3 Setting controller inhibit
Purpose
Controller inhhibit can be set e.g. in case of an interference (LU, OU, ¡).
Function
When controller inhibit (CINH) is set, the BRK-OUT signal is immediately set to HIGH. The drive is
then braked by its mechanical brake.
If the fault iseliminated quickly, i.e. ifthecontroller inhibit (CINH)is reset beforetheactual speed falls
below the threshold BRK-Nx, the BRK-OUT signal is immediately set to LOW. The drive
synchronizes itself to the momentary speed and follows its setpoint.
If the value falls below the threshold, the drive starts as described under ”Open brake”.
