N O T I C E
This option is only available with software version 48.XX.
Activates synchronization mode.
Activates cyclic synchronous position mode.
Activates cyclic synchronous velocity mode.
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.
Parameter 1-01 Motor Control Principle
Table 59: Parameter 1-01 Motor Control Principle
1-01 Motor Control Principle
Default value: Size related
Change during operation: False
Select which motor control principle to employ.
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.
Voltage vector control principle is suitable for most applications. The main benefit of VVC+ operation is
that it uses a robust motor model.
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.
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.
