State (Symbol )
- NN: State name
- X/Y/Z: State outputs/operations
X = 1 Open the brake. The relay output set to brake on/off control energizes.
Y = 1 Forced start. The function keeps the internal Start on until the brake is closed in
spite of the status of the external Start signal.
Z = 1 Ramp in zero. Forces the used speed reference (internal) to zero along a ramp.

State change conditions (Symbol )
1) Brake control active 0 -> 1 OR Inverter is modulating = 0
2) Motor magnetised = 1 AND Drive running = 1
3) Brake is open AND Brake open delay passed AND Start = 1
4) Start = 0
5) Start = 0
6) Start = 1
7) Actual motor speed < Brake close speed AND Start = 0
8) Start = 1
9) Brake is closed AND Brake close delay passed = 1 AND Start = 0
