4.2 Parameters: 1-** Load and Motor

1-00 Configuration Mode
Option: Function:
Select the application control principle to be
used when a remote reference (that is analog
input or fieldbus) is active.
[0] Open Loop Enable speed control (without feedback signal
from motor) with automatic slip compen-
*
sation for almost constant speed at varying
loads. Compensations are active, but can be
disabled in parameter group 1-0* Load and
Motor.
[1] Speed Enable speed closed-loop control with
closed loop feedback. 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 Control.
[2] Torque Enable torque closed-loop control with speed
closed loop
feedback. Only possible when option [1] VVC
is selected in parameter 1-01 Motor Control
Principle.
[3] Process Enable the use of process control in the
Closed Loop frequency converter. The process control
parameters are set in parameter groups 7-2*
Process Ctrl. Feedback and 7-3* Process PID Ctrl.

1-01 Motor Control Principle
Option: Function:
NOTICE
[0] U/f
When running U/f, control slip and load
compensations are not included.
Used for parallel-connected motors and/or special
motor applications. Set the U/f settings in
parameter 1-55 U/f Characteristic - U and
parameter 1-56 U/f Characteristic - F.
NOTICE
[1] VVC+
*
When parameter 1-10 Motor Construction is
set to PM-enabled options, only VVC
is available.
Normal running mode, including slip and load
compensations.

This parameter cannot be adjusted while
the motor is running.
This parameter defines the term clockwise
corresponding to the LCP direction arrow. Used for
easy change of direction of shaft rotation without
swapping motor wires.
