Control And Status Word 1 - Siemens SINAMICS G120C Operating Instructions Manual

The telegrams use - with the exception of telegram 999 (free interconnection via BICO) - the
word by word transfer of send and receive data (r2050/p2051).
If you require an individual telegram for your application (e.g. for transferring double words),
you can adapt one of the predefined telegrams via parameters p0922 and p2079. For
details, please 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 puls-
es).
Switch-on motor (pulses can be enabled).
The inverter immediately sets its ramp-
function generator output to 0.
The ramp-function generator can be ena-
bled.
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 gen-
erator.
Motor accelerates with the ramp-up time
p1120 to the setpoint.
Acknowledge fault. If the ON command is
still active, the inverter switches to"closing
lockout" state.
