Explanation
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 fol‐
lows 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 the "switching
on inhibited" state.
Inverter ignores the process data from the field‐
bus.
Control via fieldbus, inverter accepts the proc‐
ess data from the fieldbus.
Invert setpoint in the inverter.
Increase the setpoint saved in the motorized
potentiometer.
tentiometer.
Changes over between settings for different
operation 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 opera‐
tion" (STW1.3), the inverter switches on the
motor.
