Explanation
Quick stop: The motor brakes with the OFF3
ramp-down time p1135 down to standstill.
The motor can be switched on (ON command).
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 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"closing lockout"
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.
