1-0* General Settings
"
Determines whether the frequency converter should
be in speed mode or torque mode. Also whether the
internal PID control should be active or not.
1-00 Configuration Mode
Option:
*
Speed open loop
Speed closed loop
Torque
Process
Function:
Speed open loop[0]: 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.
Speed closed loop[1]: Enables encoder feedback
from motor. Obtain full holding torque at 0 RPM.
Increased speed accuracy: Provide a feedback
signal and set the speed PID control.
Torque [2]: Connect the encoder speed feedback
signal to the encoder input.
Only possible with "Flux with encoder
feedback", par. 1-01.
Process [3]: Enables the use of process control
in the frequency converter. The process control
parameters are set in par. groups 7-2* and 7-3*.
Par. 1-00 cannot be adjusted while the
motor is running.
1-01 Motor Control Principle
Option:
U/f
*
plus
VVC
Flux sensorless (FC 302 only)
Flux w/ motor feedback(FC302 only)
Function:
Determines which motor control principle to employ.
[0] U/f is special motor mode. Used for special
motor applications as parallel connected motors.
Generally, the best shaft performance is obtained
in the two Flux Vector control modes Flux w/
encoder feedback [3] and Flux sensorless [2]. Most
applications, however, are easily handled using a
Voltage Vector control mode VVC
benefit of VVC plus operation is a simpler motor model.
Par. 1-01 cannot be adjusted while the
motor is running.

1-02 Flux Motor Feedback Source
Option:
*
24 V encoder
MCB 102
Function:
24 V encoder [1] is a A and B channel encoder.
The encoder can be connected to the digital
inputs terminals 32/33 only.
MCB 102 [2] is selection of encoder module.
Par. 1-02 cannot be adjusted while the
motor is running.
This parameter only appears in FC 302.
1-03 Torque Characteristics
Option:
*
Constant torque
Variable torque
Auto energy optim.
Function:
Select the demanded torque characteristic. AEO and
VT are different kinds of energy saving operation.
Constant torque [0]: The motor shaft output will
provide constant torque by variable speed control.
Variable Torque [1]: The motor shaft output will
provide a variable torque by variable speed control.
Set variable torque level in par. 14-40.
Automatic Energy Optimizing function [2]:
Automatically adjusts the optimized energy
consumption by setting par. 14-41 and par. 14-42
1-05 Local Mode Configuration
Option:
Speed open loop
Speed closed loop
*
As conf. mode par. 1-00
Function:
Select which application configuration mode (par.
1-00) to use when a Local (LCP) Reference is
active. A Local Reference can only be active if
par. 3-13 is [0] or [2]. By default the Local
Reference is only active in Hand Mode.

1-10 Motor Construction
Option:
*
Asynchronous
PM, non salient SPM (FC 302 only)
Function:
Motor construction can either be asynchronous
or permanent magnet (PM) motor.
