8.1.5 3RW44 in an Inside Delta Circuit
Reversed direction of rotation in an inside delta circuit
1) For permissible main and control voltage values, refer to Technical Data, pages 9-7 to 9-11.
2) Caution: risk of restart!
The start command (e.g. by the PLC) must be reset before a reset command is issued, since an automatic
restart is executed when a start command is pending after the reset command is issued. This especially
applies to motor protection tripping.
For safety reasons it is recommended to integrate the group error output (terminals 95 and 96) into the
control.
