Group 26: Motor Control
This group defines variables used for motor control.
Code Description
2601
FLUX OPTIMIZATION
Changes the magnitude of the flux depending on the actual load. Flux Optimization can reduce the total energy
consumption and noise, and it should be enabled for drives that usually operate below nominal load.
0 =
OFF
– Disables the feature.
1 =
ON
– Enables the feature.
2602
FLUX BRAKING
Provides faster deceleration by raising the level of
magnetization in the motor when needed, instead of
limiting the deceleration ramp. By increasing the flux in
the motor, the energy of the mechanical system is
changed to thermal energy in the motor.
0 =
OFF
– Disables the feature.
1 =
ON
– Enables the feature.
2603
IR COMP VOLT
Sets the IR compensation voltage used for 0 Hz.
• Keep IR compensation as low as possible to prevent
overheating.
• Typical IR compensation values are:
IR Compensation
• When enabled, IR Compensation provides an extra
voltage boost to the motor at low speeds. Use IR
Compensation, for example, in applications that require a
high breakaway torque.
2604
IR COMP FREQ
Sets the frequency at which IR compensation is 0 V (in
% of motor frequency).
