Explanation
The output of the ramp-function generator
stops at the actual value.
The output of the ramp-function generator fol‐
lows the setpoint.
The converter brakes the motor with the ramp-
down time p1121 of the ramp-function gener‐
ator.
Motor accelerates to the setpoint with the ramp-
up time p1120.
Acknowledge fault. If the ON command is still
active, the converter switches to the "switching
on inhibited" state.
Converter ignores the process data from the
fieldbus.
Control via fieldbus, converter accepts the proc‐
ess data from the fieldbus.
Invert setpoint in the converter.
Increase the setpoint saved in the motorized po‐
tentiometer.
Reduce the setpoint saved in the motorized po‐
tentiometer.
Changes over between settings for different op‐
eration interfaces (command data sets).
Remarks
Power supply switched on; electronics initial‐
ized; pulses locked.
Motor is switched on (ON/OFF1 = 1), no fault is
active. With the command "Enable operation"
(STW1.3), the converter switches on the motor.
Motor follows setpoint. See control word 1,
bit 3.
The converter has a fault. Acknowledge fault
using STW1.7.
Coast down to standstill is not active.
