Operating modes
Parameters
VFC n-control &
Group
VFC n-control & group (only with MCV, MCH) in parameter set 1 only.
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, rated frequency and rated pow-
er. One motor of the group must be operated with speed control and be equipped with
an incremental encoder that is connected to X15. The other motors of the group follow
the speed controlled motor depending on the slip. The following encoders can be used
as incremental encoder:
•
Hiperface
®
encoder
•
TTL sensors with negated tracks, encoders with signal level to RS422
•
High-resolution incremental encoder with sine shaped tracks 1 V
SS
SEW-EURODRIVE recommends the use of encoders with 1,024 increments/revolution.
The startup function of SHELL not only supports motor startup (VFC) but also the addi-
tional controller setting of the speed controller. The following parameters relevant for n-
control are set:
Setting the parameter P820 4-quadrant operation 1 will be ignored; 4-quadrant opera-
tion is always active.
VFC n-control &
IPOS
VFC n-control & IPOS (only with MCV, MCH) in parameter set 1 only.
Must be set if IPOS

positioning commands are to be processed. Refer to the
"IPOS

Positioning and Sequence Control System" manual for detailed descriptions
of IPOS
plus
. This manual can be obtained from SEW-EURODRIVE.
