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] Linked to Hand/Auto or [1] Remote.
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 parameter group 1-0* Load/Motor. The speed
control parameters are set in parameter group
7-0* Speed PID Ctrl.
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* Speed PID Ctrl.
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*
Process Ctrl. Feedb. and 7-3* Process PID Ctrl.
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*
Torque PI Control.
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* Process Ctrl.
Feedb. and 7-3* Process PID Ctrl.
Specific parameters in parameter group 7-2*
Process Ctrl. Feedb. to 7-5* Ext. Process PID Ctrl.
Specific parameters in parameter group 7-2*
Process Ctrl. Feedb. to 7-5* Ext. Process PID Ctrl.

1-01 Motor Control Principle
Option:
[0] U/f
[1] VVC+
[2] Flux
sensorless
[3] Flux w/
motor feedb
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.
NOTICE
An overview of possible combinations of the settings in
1-00 Configuration Mode and 1-01 Motor Control Principle
can be found in 4.1.3 Active/Inactive Parameters in
Different Drive Control Modes.
1-02 Flux Motor Feedback Source
Option:

Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
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 1-55 U/f Charac-
teristic - U and 1-56 U/f Characteristic - F.
Voltage Vector Control principle suitable for
most applications. The main benefit of VVC
operation is that it uses a robust motor model.
Flux Vector control without encoder feedback,
for simple installation and robustness against
sudden load changes. FC 302 only.
Very high accuracy speed and torque control,
suitable for the most demanding applications.
FC 302 only.
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select the interface at which to receive
feedback from the motor.
A and B channel encoder, which can be
connected to the digital input terminals
32/33 only. Terminals 32/33 must be
programmed to No operation.
Encoder module option which can be
configured in parameter group 17-1* Inc. Enc.
Interface,FC 302 only.
Optional resolver interface module which can
be configured in parameter group 17-5*
Resolver Interface.
