17.17 Parallel operation of several motors on one inverter (group drives)
Such a dimensioning at present is not yet supported by the DSD.
[17-6] Group drives
Remedy
When entering the data in the DSD, divide the masses, moments of inertia, and tensile forces or
counterforces by the number of motors involved in the application (applies to the motor and gear-
box selection). The inverter in this case has to be selected manually, since it has to operate the sum
of the motors.
Note!
Relevant only for specific applications, e. g. hoists, winders, caterpullar take-offs, pumps
and power conveyors.
