Explanation
Quick stop: The motor brakes with the
OFF3 ramp-down time p1135 down to
standstill.
command).
Immediately switch-off motor (cancel
pulses).
Switch-on motor (pulses can be ena‐
bled).
The inverter immediately sets its ramp-
function generator output to 0.
The ramp-function generator can be
enabled.
The output of the ramp-function gener‐
ator stops at the actual value.
The output of the ramp-function gener‐
ator 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 com‐
mand is still active, the inverter
switches to "closing lockout" 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 mo‐
torized potentiometer.
Reduce the setpoint saved in the mo‐
torized potentiometer.
