4.2 Parameters: 1-** Load and Motor
4.2.1 1-0* General Settings
1-00 Configuration Mode
Option:
Function:
Select the application control principle to be
used when a remote reference (that is, via
analog input or fieldbus) is active.
[0]
*
Open Loop
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
and Motor
. The speed control parameters are
set in parameter group
7-0* Speed PID Control
.
[1]
Speed
closed loop
Enables speed closed-loop control with
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
closed loop
Enables torque closed-loop control with speed
feedback. Only possible when option
[1] VVC
+
is selected in
parameter 1-01 Motor Control
Principle
.
[3]
Process
Closed Loop
Enables the use of process control in the
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:
[0]
U/f
NOTICE
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
.
[1]
*
VVC+
NOTICE
When
parameter 1-10 Motor Construction
is
set to PM-enabled options, only VVC
+
option
is available.
1-01 Motor Control Principle
Option:
Function:
Normal running mode, including slip and load
compensations.
1-03 Torque Characteristics
Option:
Function:
Select the torque characteristic
required. VT and AEO are both
energy-saving operations.

1-06 Clockwise Direction
Option:
Function:
NOTICE
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.
[0]
*
Normal The motor shaft turns in clockwise direction when
frequency converter is connected U
⇒
U; V
⇒
V; and
W
⇒
W to motor.
[1]
Inverse The motor shaft turns in counterclockwise
direction when frequency converter is connected
U
⇒
U; V
⇒
V; and W
⇒
W to motor.
1-08 Motor Control Bandwidth
Option:
Function:
[0] High
Suitable for high dynamic response.
[1] Medium
Suitable for smooth steady-state operation.
[2] Low
Suitable for smooth steady-state operation with
lowest dynamic response.
[3] Adaptive 1 Optimised for smooth steady-state operation,
with extra active damping.
[4] Adaptive 2 This is an alternative to Adaptive 1, which
focuses on low-inductance PM motors.
