Description of function
Control word 1 (STW1)
Control → Converter
Bit Drive function Explanation
00 0 = OFF1 The motor brakes with the ramp-down
time p1121 of the ramp-function gener‐
ator. The converter switches o󹪜 the mo‐
tor at standstill.
0→1 = ON The converter goes into "Ready" state. If,
in addition, bit3=1, the converter
switches on the motor.
01 0 = OFF2 Switch o󹪜 motor immediately, the motor
then coasts down.
1 = No OFF2 The motor can be switched on (ON com‐
mand).
02 0 = Quick stop (OFF3) Quick stop: The motor brakes to a stand‐
still with the OFF3 ramp-down time
p1135.
1 = No quick stop (OFF3) The motor can be switched on (ON com‐
mand).
03 0 = Inhibit operation Immediately switch o󹪜 motor (suppress
pulses).
1 = Enable operation Switch on motor (pulses can be ena‐
bled).
04 0 = Inhibit RFG The converter immediately sets its ramp-
function generator output to0.
1 = Do not inhibit RFG The ramp-function generator can be en‐
abled.
05 0 = Stop RFG The output of the ramp-function genera‐
tor stops at the current value.
1 = Enable RFG The output of the ramp-function genera‐
tor follows the setpoint.
06 0 = Inhibit setpoint The converter brakes the motor with the
ramp-down time p1121 of the ramp-
function generator.
1 = Enable setpoint Motor accelerates to the setpoint with
the ramp-up time p1120.
07 0→1 = Acknowledge faults Acknowledge fault. If the ON command
is still active, the converter switches to
"closing lockout" state.
