the inverter
2 0 = Quick stop (OFF3) Quick stop: The motor brakes with the OFF3
ramp-down time p1135 down to standstill.
p0848[0] =
r2090.2
The motor can be switched on (ON command).
3
Immediately switch-off motor (cancel pulses).
p0852[0] =
r2090.3
Switch-on motor (pulses can be enabled).
4 0 = Disable RFG The inverter immediately sets its ramp-function
p1140[0] =
r2090.4
The ramp-function generator can be enabled.
5 0 = Stop RFG The output of the ramp-function generator stops
p1141[0] =
r2090.5
1 = Enable RFG The output of the ramp-function generator follows
6 0 = Inhibit setpoint The inverter brakes the motor with the ramp-
down time p1121 of the ramp-function generator.
p1142[0] =
r2090.6
1 = Enable setpoint Motor accelerates with the ramp-up time p1120 to
7 0 → 1 = Acknowledge faults Acknowledge fault. If the ON command is still
active, the inverter switches to"closing lockout"
p2103[0] =
r2090.7
10
Inverter ignores the process data from the fieldbus.
p0854[0] =
r2090.10
1 = Control via PLC Control via fieldbus, inverter accepts the process
data from the fieldbus.
11 1 = Direction reversal Invert setpoint in the inverter. p1113[0] =
12 Not used
