1-03 Torque Characteristics
Option:
Function:
Select the torque characteristic required.
VT and AEO are both energy saving operations.
[0]
*
Constant
torque
Motor shaft output provides constant torque
under variable speed control.
[1]
Variable
torque
Motor shaft output provides variable torque
under variable speed control. Set the variable
torque level in
14-40 VT Level
.
[2]
Auto
Energy
Optim.
Automatically optimizes energy consumption by
minimizing magnetization and frequency via
14-41 AEO Minimum Magnetisation
and
14-42 Minimum AEO Frequency
.
[5]
Constant
Power
The function provides a constant power in the
field weakening area.
The torque shape of motor mode is used as a
limit in generator mode. This is done to limit the
power in generatoric mode that otherwise
becomes considerable larger than in motor
mode, due to the high DC link voltage available
in generator mode.
Pshaft W = ωmech rad/s × T Nm
This relationship with the constant power is

1-04 Overload Mode
Option:
Function:
[0]
*
High torque
Allows up to 160% overtorque.
[1]
Normal torque For oversized motor - allows up to 110%
overtorque.
NOTE!
This parameter cannot be adjusted while the motor is
running.
1-05 Local Mode Configuration
Option:
Function:
Select which application configuration
mode (
1-00 Configuration Mode
), i.e., the
application control principle, to use when a
Local (LCP) Reference is active. A local
reference can be active only when
3-13 Reference Site
is set to [0] or [2]. By
default, the local reference is active in hand
mode only.

1-06 Clockwise Direction
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. (Valid from SW
version 5.84)
Option:
Function:
[0]
*
Normal
Motor shaft will turn in clockwise
direction when the Adjustable
frequency drive is connected U ->
U; V -> V, and W -> W to motor.
[1]
Inverse
Motor shaft will turn in counter
clockwise direction when the
Adjustable frequency drive is
connected U -> U; V -> V, and W -
> W to motor.
NOTE!
This parameter cannot be changed while the motor is
running.
