Parameter set switchover
This function serves for operating two motors on one inverter using two different para-
meter sets.
Parameter sets are switched using a binary input. For this purpose, a binary input must
be set to “PARAM. SWITCHOVER” (
→
P60_/P61_). You can then change from para-
meter set 1 to 2 and vice versa in INHIBITED inverter status.

NOTES
•
For operation with encoder feedback, do not change parameter sets in cycles fast-
er than 2 seconds. This makes sure that the encoders can be initialized.
•
A changeover contactor should be provided for each of the two motor cables when
two motors are operated alternately on the same inverter with the parameter set
switchover function in use ( P60
→
P61_/ PARAM. SWITCHOVER). Only switch
changeover contactors when the unit is inhibited!
•
Parameter set 2 allows for VFC operating modes without speed control only. Speed
control or CFC and SERVO operating modes are not possible.
