Synchroniza-
tion
N O T I C E
This option is only available with software version 48.XX.
Activates synchronization mode.
[11]
Cyclic sync. po-
sition
Activates cyclic synchronous position mode.
[12]
Cyclic sync. ve-
locity
Activates cyclic synchronous velocity mode.

Mode of opera-
tion DS402
DS 402 operation modes are selected by
parameter 1-09 Mode of Operation
. With this selection,
pa-
rameter 8-10 Control Word Profile
is automatically set to
[7] CANopen DSP 402
and the control word
bits are used according to the DS 402 profile based on the selection in
parameter 1-09 Mode of Opera-
tion
.

U/f
Special motor mode, for parallel-connected motors in special motor applications. When U/f is selected,
the characteristic of the control principle can be edited in
parameter 1-55 U/f Characteristic - U
and
param-
eter 1-56 U/f Characteristic - F
.
[1]
VVC+
Voltage vector control principle is suitable for most applications. The main benefit of VVC+ operation is
that it uses a robust motor model.
[2]
Flux sen-
sorless
N O T I C E
This option is only available in FC 302.
Flux vector control without encoder feedback, for simple installation and robustness against sudden load
changes.
[3]
Flux w/
motor
N O T I C E
This option is only available in FC 302.
High accuracy speed and torque control, suitable for the most demanding applications.
The best shaft performance is normally achieved using either of the 2 flux vector control modes
[2] Flux sensorless
and
[3] Flux with
encoder feedback
.
