IACDRIVE I5000 Series Operation Manual page 50

The value of torque boost should be determined by the load. The heavier the load, the larger the
value.
Notice: P4.01 should not be too large, otherwise the motor would be over-heat or the
inverter would be tripped by over-current or over-load.
If P4.01 is set to be 0, the inverter will boost the output torque according to the load automatically.
Please refer to following diagram.
Function
Code
P4.03
compensation limit
The slip compensation function calculates the torque of motor according to the output current and
compensates for output frequency. This function is used to improve speed accuracy when
operating with a load. P4.03 sets the slip compensation limit as a percentage of motor rated slip,
with the motor rated slip taken as 100%.

Code
P4.04 saving selection
When P4.04 is set to be 1, while there is a light load, it will reduce the inverter output voltage
and saves energy.
