Setting value Lock selection

• Locks the setting value to prevent setting errors.

The setting item to be locked is dependent on the designation.

• PID auto-tuning cannot be carried out when Lock1 or Lock2

is selected.

•

(Unlock) : All setting values can be changed.

(Lock 1) : None of setting values can be changed.

(Lock 2) : Only main setting mode can be changed.

Unlock

(Lock 3) : All setting values can be changed except Controller/Converter

function selection. However, do not change each setting item of

Auxiliary function setting mode 2.

Changed data reverts to their former value after power is turned

off because they are not saved in the non-volatile memory. Lock

3 is suitable when our programmable controller (with SVTC) is

used together because it has noting to do with memory life.
