Function:
Select the application control principle to be
used when a Remote Reference (i.e. via
analog input or fieldbus) is active. A Remote
Reference can only be active when
3-13 Reference Site is set to [0] or [1].
Enables speed control (without feedback
signal from motor) with automatic slip
compensation for almost constant speed at
varying loads.
Compensations are active but can be
disabled in the Load/Motor parameter group
1-0*. The speed control parameters are set in
parameter group 7-0*.
Enables Speed closed loop control with feed-
back. Obtain full holding torque at 0 RPM.
For increased speed accuracy, provide a
feedback signal and set the speed PID
control. The speed control parameters are set
in parameter group 7-0*.
Enables torque closed loop control with feed-
back. Only possible with "Flux with motor
feedback" option, 1-01 Motor Control Principle.
FC 302 only.
Enables the use of process control in the
frequency converter. The process control
parameters are set in parameter groups 7-2*
and 7-3*.
Enables the use of torque open loop in VVC
mode (1-01 Motor Control Principle). The
torque PID parameters are set in parameter
group 7-1*.
Enables the wobble functionality in
30-00 Wobble Mode to 30-19 Wobble Delta
Freq. Scaled.
Enables the surface winder control specific
parameters in parameter group 7-2* and
7-3*.
Specific parameters in parameter group 7-2*
to 7-5*.
Specific parameters in parameter group 7-2*
to 7-5*.

The best shaft performance is normally achieved using
either of the two Flux Vector control modes [2] Flux
sensorless and [3] Flux with encoder feedback.
NOTE
This parameter cannot be adjusted while the motor is
running.

An overview of possible combinations of the settings in
1-00 Configuration Mode and 1-01 Motor Control Principle
can be found in 4.1.1 Conversion.
