Introduction
The following section describes startup of synchronous operation for a two-column hoist
(
→
following figure).
Both drives are equipped with identical gear units with identical ratios; the rated power
of the motors and inverters are the same. For both drives, clockwise rotation on the
motor stands for upward movement on the hoist. Therefore, the prefabricated
master/slave cable (part number 818 166 7) from SEW-EURODRIVE can be used to
connect master X14 to slave X42.
