Motor Cable Length Parameter
To achieve higher motor control performance, the WJ200 inverter has the Motor Cable
Length Parameter setting B033. Normally there is no need to adjust this parameter,
however in case of long motor cable and/or shielded cable, where there is a
comparatively higher earth capacitance, set this parameter higher to achieve better
motor control performance.
Note that the parameter is indicative and no formula to calculate the suitable value.
Normally, longer the motor cable, bigger the set value. Please adjust depending on your
system.
For 11 and 15kW inverter, it is not needed to set b033.
