Bit Significance
Explanation
Signal inter‐
connection in
the converter
0
0 = OFF1
The motor brakes with the ramp-down time p1121 of
the ramp-function generator. The converter switches
off the motor at standstill.
p0840[0] =
r2090.0
0 → 1 = ON
The converter goes into the "ready" state. If, in addition
bit 3 = 1, then the converter switches on the motor.
1
0 = OFF2
Switch off the motor immediately, the motor then
coasts down to a standstill.
p0844[0] =
r2090.1
1 = No OFF2
The motor can be switched on (ON command).
2
0 = Quick stop (OFF3)
Quick stop: The motor brakes to a standstill with the
OFF3 ramp-down time p1135.
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 converter immediately sets its ramp-function gen‐
erator 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 converter brakes the motor with the ramp-down
time p1121 of the ramp-function generator.
p1142[0] =
r2090.6
1 = Enable setpoint
Motor accelerates to the setpoint with the ramp-up
time p1120.
7
0 → 1 = Acknowledge
faults
Acknowledge fault. If the ON command is still active,
the converter switches to the "switching on inhibited"
state.
p2103[0] =
r2090.7
8, 9 Reserved
10 0 = No control via PLC
Converter ignores the process data from the fieldbus. p0854[0] =
r2090.10
1 = Control via PLC
Control via fieldbus, converter accepts the process
data from the fieldbus.
11 1 = Direction reversal
Invert setpoint in the converter.
p1113[0] =
r2090.11
12 Reserved
13 1 = MOP up
Increase the setpoint saved in the motorized potenti‐
ometer.
p1035[0] =
r2090.13
14 1 = MOP down
Reduce the setpoint saved in the motorized potenti‐
ometer.
p1036[0] =
r2090.14
15 Reserved
