Software lock mode

NOTE: To disable parameter editing when using  lock modes  and , assign the

[SFT] function to one of the intelligent input terminals.

See "Software Lock" in chapter 4

Motor Cable Length Parameter

To achieve higher motor control performance, the WJ200 inverter has the Motor Cable

Length Parameter setting . 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

For 11 and 15kW inverter, it is not needed to set b033.

"b" Function

Prevents parameter changes, in five

options, option codes:

all parameters except  are

locked when [SFT] terminal is ON

all parameters except  and

output frequency  are locked

when [SFT] terminal is ON

all parameters except  are

all parameters except  and

output frequency  are locked

High level access including 

See appendix C for the accessible

parameters in this mode.
