telegram, then the inverter automatically interconnects parameters r2050, r2060 and r2090
…r2093 with the appropriate signals.
If you wish to adapt a predefined telegram, then you must interconnect the send and receive
data with the appropriate signals. To facilitate manual interconnection of send and receive
data, you must first adapt parameters p0922 and p2079.
Extending the telegram (Page 129)
For additional details relating to freely interconnecting process data, refer to the List Manual,
function diagrams 2420 and 2472.

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 com-
mand).
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 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
