Control function reversing starter

Description
This control function allows the motor starter to control the direction in which motors rotate.
Simultaneous activation of both directions of rotation is prevented by the internal logic.
Delayed switching from one direction of rotation to the other is implemented by means of the
lock-out time.
Note
To reverse the direction of rotation, a mechanically-switching reversing contactor is
integrated in reversing starters with electronic switching. The preferred position of this
contactor after power-up is "CW rotation". When the direction is changed to "CCW rotation",
the reversing contactor is activated first, followed by the electronic contacts after an 80 ms
delay.
Lock-out time
The lock-out time results in delayed switching of the direction of rotation. The rotating mass
of a drive must come to a standstill during the lock-out time before the next switching
command can be executed.
Note
A lock-out time set to 0 is set internally to 150 ms for safety purposes.
