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 to a standstill with the
OFF3 ramp-down time p1135.
Immediately switch-off motor (cancel pulses).
Switch-on motor (pulses can be enabled).
The converter immediately sets its ramp-function gen‐
erator 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 to the setpoint with the ramp-up
time p1120.
Acknowledge fault. If the ON command is still active,
the converter switches to the "switching on inhibited"
state.
Converter ignores the process data from the fieldbus. p0854[0] =
Control via fieldbus, converter accepts the process
data from the fieldbus.
Invert setpoint in the converter.
Increase the setpoint saved in the motorized potenti‐
ometer.
Reduce the setpoint saved in the motorized potenti‐
ometer.
