How to Program
" Parameters: Load and Motor
" 1-0* General Settings
1-00 Configuration Mode
Option:
*
Speed open loop [0]
Speed closed-loop [1]
Torque [2]
Function:
Speed control, open loop: Enables speed control
(without fe edback sig n al from motor) with automatic
slip compensation for almost constant s peed at
varying loads. Compensations are active, but can
be disabled in the Load / Motor parameter group.
Speed control, closed loop: Enables encoder
feedback from motor. Obtain full holding torque
at 0 RPM. Increased spe ed accuracy: Provide a
feedback signal and set the spe ed PID controller.
Torque control, speed feedback: Connect the
encoder speed feedback signal to the encoder input.
Only possib le with "Flux wit h encoder
feedback", par. 1-01.
1-01 Motor Control Principle
Option:
U/f [0]
VVC
plus
[1]
Flux sensorless [2]
Flux w/ motor feedback [3]
Function:
Determines which m otor control princ iple to e mploy.
[0] U/f is spec ial m otor mode. Used for specia l
motor applications as parallel connected motors.
Generally, the best shaft performance is obtained
in the two Flux Vector control m ode s Flux w/
encoder feedback [3] and Flux sensorless [2]. Most
applications, however, are easily handled u sing a
Voltage Vector control mode VVC
plus
[1]. T
he main
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 [1]
MCB 102 [2]
Function:
24 V encoder [1] is an 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.
1-03 Torque Characteristics
Option:
*
Constant torque [0]
Variable torque [1]
Auto Energy Optim. [2]
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.
Setvariabletorquelevelinpar. 14-40.
Automatic Energy Optimizing function [2 ]:
Automatically adjusts the optimize d energy
consumption by setting par. 14-41 and par. 14-42
1-05 Local Mode Configuration
Option:
Speed o pen-loop [0]
Speed closed-loop [1]
*
As conf. mode P. 1-00 [2]
Function:
Select w h ich 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 L ocal
Reference i s only active in Hand Mode.

Function:
Motor construction can either b
