Control And Status Word 1 - Siemens SINAMICS G120 Operating Instructions Manual

The telegrams use - with the exception of telegram 999 (free interconnection) - 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 adjust 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 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.
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.
