Function Parameter name
code
This function is mostly used in textile and chemical industry and some application such as traversing and winding
so it is used for balancing the workload allocation when multiple motors are used to drive the same load. The
output frequency of the frequency inverters decreases as the load increases. You can reduce the workload of the
motor under load by decreasing the output frequency for this motor, implementing workload balancing among
multiple motors.P01.44 or P01.46=0,This function disable
