Operating modes
VFC 1 / 2
Default setting for asynchronous motors without encoder feedback. Suitable for general
applications, such as conveyor belts, trolleys, and hoists with counterweight. A flux-ori-
ented motor model is used. This model is optimally adapted to the motor after the startup
function in SHELL or in the DBG60B keypad has been carried out. It is necessary to en-
ter the motor type (SEW motor) or the nameplate data (motor from another manufactur-
er) as part of the startup function. The following parameters are preset (parameter set
1/2):
NOTE
For operating modes with encoder feedback, parameters must not be changed in
cycles faster than 2 seconds. This makes sure that the encoders can be initialized.

NOTES
•
SEW-EURODRIVE recommends using the P320 Automatic adjustment 1 / P330
Automatic adjustment 2 activated in the factory setting. The result is an automatic
setting during the pre-magnetization phase by calibrating the motor of P322 IxR
compensation 1 / P332 IxR compensation 2 .
•
SEW-EURODRIVE recommends keeping the parameters P321 Boost 1 / P331
Boost 2 at the factory setting (= 0).
