1-02 Flux Motor Feedback Source
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
The options 12 and 13 are only available
for software version 48.XX.
Select the source of the feedback for flux
closed loop motor control. Set
parameter 1-01 Motor Control Principle
to
[3] Flux
with motor feedback option
.
The feedback device is typically mounted
directly on the motor shaft. The feedback
device can also be mounted in the application
provided the gear ratio between motor and
encoder is fixed and accurate.
Configure the gear ratio between motor and
encoder in
parameter 7-94 Position PI Feedback
and
without any
rounding error.

1-03 Torque Characteristics
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
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
[2] Auto
Energy
Optim.
Automatically optimizes energy consumption by
minimizing magnetization and frequency via
parameter 14-41 AEO Minimum Magnetisation
and
parameter 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 the generator mode. This is done to limit
the power in generator mode that otherwise
becomes considerably larger than in motor
mode, due to the high DC-link voltage available
in generator mode.

Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
Use this parameter to configure the frequency
converter for either high or normal overload.
When selecting the frequency converter size,
always review the technical data in the
operating guide
or the
design guide
to know the
available output current.
