10.15 Reversing starter control function
Description
This control function can be used by the RSe motor starter to control the motor
rotation directions. An internal logic prevents both contactors being switched on
at the same time.
The time-delayed switchover from one rotation direction to the other direction is
realized by the interlock time.
10.15.1 Device parameters
Interlock time (can only be parameterized with high feature motor starters)
The ’interlock time’ effects the time-delayed switchover of the rotation direction.
Within the interlock time, the centrifugal mass of a drive should come to
a standstill before the next switching command can be executed.
Range: 0 to 60 seconds
Caution
An interlock time of 0 means 150 milliseconds for safety reasons.
