1 = No quick stop (OFF3) The motor can be switched on (ON com-
mand).
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
follows 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

Reserved
10 0 = No control via PLC Inverter ignores the process data from the
fieldbus.
p0854[0] =
r2090.10
1 = Control via PLC Control via fieldbus, inverter accepts the pro-
cess data from the fieldbus.
11 1 = Direction reversal Invert setpoint in the inverter. p1113[0] =
r2090.11
