Explanation
The motor brakes with the ramp-down time p1121 of the ramp-
function generator. The converter switches off the motor at
standstill.
The converter goes into the "ready" state. If, in addition bit 3 = 1,
then the converter 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 converter 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 converter 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 the fault. If the ON command is still active, the
converter switches to"closing lockout" state.
Converter ignores the process data from the fieldbus.
Control via fieldbus, converter accepts the process data from the
fieldbus.
Invert setpoint in the converter.
Increase the setpoint saved in the motorized potentiometer.
Reduce the setpoint saved in the motorized potentiometer.
Changes over between settings for different operation interfaces
(command data sets).
