Explanation
The motor brakes with the ramp-down time
p1121 of the ramp-function generator. The
inverter switches off the motor at standstill.
The inverter goes into the "ready" state. If, in
addition bit 3 = 1, then the inverter switches
on the motor.
Switch off the motor immediately, the motor
then coasts down to a standstill.
The motor can be switched on (ON com-
mand).
Quick stop: The motor brakes with the OFF3
ramp-down time p1135 down to standstill.
The motor can be switched on (ON com-
mand).
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
follows the setpoint.
The inverter brakes the motor with the ramp-
down time p1121 of the ramp-function gen-
erator.
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 lock-
out" state.
Inverter ignores the process data from the
fieldbus.
Control via fieldbus, inverter accepts the pro-
cess data from the fieldbus.
Invert setpoint in the inverter.
Increase the setpoint saved in the motorized
potentiometer.
Reduce the setpoint saved in the motorized
potentiometer.
