Explanation
Switch off the motor immediately, the motor then
coasts down to a standstill.
The motor can be switched on (ON command).
Quick stop: The motor brakes with the OFF3 ramp-
down time p1135 down to standstill.
Immediately switch-off motor (cancel pulses).
Switch-on motor (pulses can be enabled).
The inverter immediately sets its ramp-function gener‐
ator 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 generator.
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 "switch-on inhibit" state.
Inverter ignores the process data from the fieldbus.
Control via fieldbus, inverter accepts the process data
from the fieldbus.
Invert setpoint in the inverter.
Increase the setpoint saved in the motorized potenti‐
ometer.
Reduce the setpoint saved in the motorized potenti‐
ometer.
Remarks
Power supply switched on; electronics initialized;
pulses locked.
Motor is switched on (ON/OFF1 = 1), no fault is
active. With the command "Enable operation"
(STW1.3), the inverter switches on the motor.
