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 command).
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 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"closing lockout" state.
Inverter ignores the process data from the fieldbus.
Control via fieldbus, inverter accepts the process data from
the fieldbus.
0 = Direction Invert setpoint in the inverter.
reversal
1 = MOP up Increase the setpoint saved in the motorized potentiometer.
1 = MOP down Reduce the setpoint saved in the motorized potentiometer.
Reserved Changes over between settings for different operation
interfaces (command data sets).
