Group 40 MOTOR CONTROL
Motor control settings, such as
• flux reference
• drive switching frequency
• motor slip compensation
• voltage reserve
• flux optimisation
• IR compensation for scalar control mode.
Flux optimisation
Flux optimisation reduces the total energy consumption and motor noise level when
the drive operates below the nominal load. The total efficiency (motor and drive) can
be improved by 1% to 10%, depending on the load torque and speed.
Note: Flux optimisation limits the dynamic control performance of the drive because
with a small flux reference the drive torque cannot be increased fast.

Firmware block:
MOTOR CONTROL
(40)
This block defines motor control
settings such as
• flux reference
• drive switching frequency
• motor slip compensation
• voltage reserve
• flux optimisation
• IR compensation for scalar control
mode.
The block also shows the flux and
torque reference used.

40.01 FLUX REF FW block: MOTOR CONTROL (see above)
Defines the flux reference.
0…200% Flux reference.
40.02 SF REF FW block: MOTOR CONTROL (see above)
Defines the switching frequency of the drive.
When switching frequency exceeds 4 kHz, the allowed drive output current is limited. See switching
frequency derating in the appropriate Hardware Manual.
