2 0 = Quick stop (OFF3) Quick stop: The motor brakes with the OFF3
ramp-down time p1135 down to standstill.
p0848[0] =
r2090.2
1 = No quick stop (OFF3) The motor can be switched on (ON command).
3 0 = Inhibit operation Immediately switch-off motor (cancel pulses). p0852[0] =
r2090.3
1 = Enable operation Switch-on motor (pulses can be enabled).
4 0 = Disable RFG The inverter immediately sets its ramp-function
generator output to 0.
p1140[0] =
r2090.4
1 = Do not disable RFG The ramp-function generator can be enabled.
5 0 = Stop RFG The output of the ramp-function generator
stops at the actual value.
p1141[0] =
r2090.5
1 = Enable RFG The output of the ramp-function generator fol‐
lows the setpoint.
6 0 = Inhibit setpoint The inverter brakes the motor with the ramp-
down time p1121 of the ramp-function genera‐
tor.
p1142[0] =
r2090.6
1 = Enable setpoint Motor accelerates with the ramp-up time p1120
to the setpoint.
7 0 → 1 = Acknowledge faults Acknowledge fault. If the ON command is still
active, the inverter switches to"closing lockout"
state.
p2103[0] =
r2090.7
8, 9 Reserved
10 0 = No control via PLC Inverter ignores the process data from the field‐
bus.
p0854[0] =
r2090.10
1 = Control via PLC Control via fieldbus, inverter accepts the proc‐
ess data from the fieldbus.
11 1 = Direction reversal Invert setpoint in the inverter. p1113[0] =
r2090.11

1 = MOP down Reduce the setpoint saved in the motorized po‐
tentiometer.
