State shifts

RFG = Ramp Function
Generator in the speed
control loop (reference
handling).
State (Symbol
- NN: State name
- X/Y/Z: State outputs/operations
X = 1
Y = 1
Z = 1
State change conditions (Symbol
1) Brake control active 0 -> 1 OR Inverter is modulating = 0
2) Motor magnetised = 1 AND Drive running = 1 and Torque prove Ok
3) Brake Acknowledge = 1 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 Acknowledge = 0 AND Brake close delay passed = 1 AND Start = 0
Only if parameter
10) Brake Acknowledge = 0 AND Brake open delay passed =1
11) Brake Acknowledge = 0
12) Brake Acknowledge = 0
13) Brake Acknowledge = 1 AND Brake close delay passed. See

Open the brake. The relay output set to brake on/off control energises.
Forced start. The function keeps the internal Start on until the brake is closed in spite of the
status of the external Start signal.
Ramp in zero. Forces the used speed reference (internal) to zero along a ramp.
