Operating modes
Parameters
VFC 1 / 2 & Group
Set this mode if a group of asynchronous motors is to be operated on one inverter. All
motors of the group must have the same rated voltage and rated frequency. The brake
is controlled via P730 Brake function 1 / P733 Brake function 2 . Set the data for the larg-
est motor in the group during startup. Following startup, P303 Current limit 1 / 313 Cur-
rent limit 2 have to be set to the total current of all connected motors. We recommend a
basic setting of P321 Boost 1 / P331 Boost 2 to the same value as P322 IxR compen-
sation 1 / P332 IxR compensation 2 .

NOTES
•
Do not use this operating mode for hoist applications.
•
The premagnetization current is adapted to the largest motor in the group during
startup. If motors are removed from the group by switching them off, it may be
necessary to reduce the current limit to a current that matches the actual combina-
tion of motors.
•
Slip compensation is not effective. Motor speeds are therefore dependent on the
load.
