4.6 Motor operators
Connection diagram for control of the motor operator MO320
Note
An EMERGENCY-STOP circuit is implemented by means of shunt trips (Page 146).
For further circuit diagrams, see chapter "Circuit diagrams" (Page 423).
The M0320 motor operator is edge-controlled, i.e. it reacts only to the positive edge of an ON
or OFF command at the relevant terminals 3 and 4. In this case, the OFF signal is dominant,
i.e. the motor operator will be switched off in response to an OFF edge even if an ON signal
is applied.
The MO320 requires a pause period of 80 ms between the end of an OFF signal and the
edge of an ON signal. Since the OFF signal is dominant, it does not require a pause period.
