The
Final Torque Reference
(04.003) is converted into the
Final Current Reference
(04.004) by applying a torque to current conversion and by applying
the
Final Current Limit
(04.018). The torque to current conversion is applied as follows:
|
Output Frequency
(05.001)| ≤
Motor Rated Frequency
(05.006)
Current reference =
Final Torque Reference
(04.003)
|
Output Frequency
(05.001)| >
Motor Rated Frequency
(05.006)
Current reference =
Final Torque Reference
(04.003) x |
Output Frequency
(05.001) | /
Motor Rated Frequency
(05.006)
It is possible to disable the flux compensation by setting
Flux Control Compensation Disable
(05.028) to 1.

The
Motoring Current Limit
(04.005) limits the current when the motor is being accelerated away from standstill. The
Regenerating Current Limit
(04.006) limits the current when the motor is being decelerated towards standstill. If the
Symmetrical Current Limit
(04.007) is below the
Motoring Current Limit
(04.005) then it is used instead of the
Motoring Current Limit
(04.005). If the
Symmetrical Current Limit
(04.007) is below the
Regenerating Current Limit
(04.006) then it is used instead of the
Regenerating Current Limit
(04.006).
The maximum possible current limit (VM_MOTOR1_CURRENT_LIMIT [MAX]) varies between drive sizes with default parameters loaded. For some
drive sizes the default value may be reduced below the value given by the parameter range limiting.
