Control word 1 (STW1)
Control word 1 (bits 0-10 in accordance with PROFIdrive profile, bits 11-15 specific to the
inverter).
Bit
Significance
Explanation
Signal intercon-
nection in the
inverter
0
0 = OFF1
The motor brakes with the ramp-down time p1121 of the ramp-function
generator. The inverter switches off the motor at standstill.
p0840[0] =
r2090.0
0
→
1 = ON
The inverter goes into the "ready" state. If, in addition bit 3 = 1, then the
inverter 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 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 opera-
tion
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 generator.
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
1 = Jog 1
The inverter switch on the motor, speed = jog 1
p1055[0] = r2090.
8
9
1 = Jog 2
The inverter switch on the motor, speed = jog 2
p1056[0]= r2090.9
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 process data from the fieldbus.
11
1 = direction rever-
sal
Invert setpoint in the inverter.
p1113[0] =
r2090.11

Reserved
13
1 = MOP up
Increase the setpoint saved in the motorized potentiometer.
p1035[0] =
r2090.13
14
1 = MOP down
Reduce the setpoint saved in the motorized potentiometer.
p1036[0] =
r2090.14
