Parameter Descriptions

3.3 Parameters: 1-** Load and Motor

3.3.1 1-0* General Settings
Define whether the frequency converter operates in speed
mode or torque mode; and whether the internal PID control
should be active or not.
1-00 Configuration Mode
Option: 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].
[0] Speed open Enables speed control (without feedback
*
loop 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*.
[1] Speed closed Enables Speed closed loop control with feed-
loop back. Obtain full holding torque at 0 RPM.
For increased speed accuracy, provide a
feedback signal and set the speed PID control.
[2] Torque Enables torque closed loop control with feed-
back. Only possible with "Flux with motor
feedback" option, 1-01 Motor Control Principle.
FC 302 only.
[3] Process Enables the use of process control in the
frequency converter. The process control
parameters are set in parameter groups 7-2*
and 7-3*.
[4] Torque open
Enables the use of torque open loop in VVC
loop
mode (1-01 Motor Control Principle). The torque
PID parameters are set in parameter group
7-1*.
[5] Wobble Enables the wobble functionality in
30-00 Wobble Mode to 30-19 Wobble Delta Freq.
Scaled.
[6] Surface Enables the surface winder control specific
Winder parameters in parameter group 7-2* and 7-3*.
[7] Extended Specific parameters in parameter group 7-2*
PID Speed to 7-5*.
OL
[8] Extended Specific parameters in parameter group 7-2*
PID Speed CL to 7-5*.

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

Function:
Select which motor control principle to
employ.
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 1-55 U/f Charac-
teristic - U and 1-56 U/f Characteristic - F.
VVC+ Voltage Vector Control principle suitable for
most applications. The main benefit of VVC
operation is that it uses a robust motor model.
Flux Flux Vector control without encoder feedback,
sensorless for simple installation and robustness against
sudden load changes. FC 302 only.
Flux w/ very high accuracy speed and torque control,
motor feedb suitable for the most demanding applications.
FC 302 only.
Function:
Select the interface at which to receive
feedback from the motor.
Motor feedb. P1-02
24V encoder 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.
MCB 102 Encoder module option which can be
configured in parameter group 17-1*
FC 302 only.
MCB 103 Optional resolver interface module
which can be configured in parameter
group 17-5*
