00 0 = OFF1 The motor brakes with the ramp-down time
p1121 of t
he ram
p-function generator. The con‐
verter switches o the motor at standstill.
0→1 = ON The converter goes into the "ready" state. If, in
addition, bit 3
= 1, the converter switches on the
motor.
01 0 = OFF2 Switch o the motor immediately, the motor
then coas
ts down to a standstill.
1 = No OFF2 The motor can be switched on (ON command).
02 0 = Quick stop (OFF3) Quick stop: The motor brakes to a standstill with
t
he OFF3 ram
p-down time p1135.
1 = No quick stop (OFF3) The motor can be switched on (ON command).
03 0 = Inhibit operation Immediately switch o mo
tor (cancel pulses).
1 = Enable oper
ation Switch on motor (pulses can be enabled).
04 0 = Inhibit RFG The converter immediately sets its ramp-func‐
tion g
enerat
or output to0.
1 = Do not inhibit RFG The ramp-function generator can be enabled.
05 0 = Stop RFG The output of the ramp-function generator stops
at t
he curr
ent value.
1 = Enable RFG The output of the ramp-function generator fol‐
lows t
he setpoint.
06 0 = Inhibit setpoint The converter brakes the motor with the ramp-
down time p1121 of the r
amp-function genera‐
tor.
1 = Enable setpoint Motor accelerates to the setpoint with the ramp-
up time p1120.
07 0→1 = Acknowledge faults Acknowledge fault. If the ON command is still
activ
e, the con
verter switches to the "switching
on inhibited" state.
