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.
For additional details relating to freely interconnecting process data, refer to the List Manual,
function diagrams 2420 and 2472.

Explanation
The motor brakes with the ramp-down time
p1121 of the ramp-function generator. The
inverter switches off the motor at standstill.
The inverter goes into the "ready" state. If, in
addition bit 3 = 1, then the inverter switches on
the motor.
Switch off the motor immediately, the motor
then coasts down to a standstill.
The motor can be switched on (ON com-
mand).
Quick stop: The motor brakes with the OFF3
ramp-down time p1135 down to standstill.
The motor can be switched on (ON com-
mand).
Immediately switch-off motor (cancel pulses).
Switch-on motor (pulses can be enabled).
The inverter immediately sets its ramp-
function generator output to 0.
The ramp-function generator can be enabled.
The output of the ramp-function generator
stops at the actual value.
The output of the ramp-function generator
follows the setpoint.
The inverter brakes the motor with the ramp-
down time p1121 of the ramp-function genera-
tor.
