Set value lock selection Unlock
• Locks the set value to prevent setting errors
The setting item to be locked depends on the selection.
• PID auto-tuning or auto-reset does not work if Lock 1 or Lock 2 is selected.
• When selecting Lock, select Lock 1, Lock 2 or Lock 3 after setting the
necessary items in the status Unlock.
• (Unlock): All set values are changeable.
(Lock 1): None of the set values can be changed.
(Lock 2): Only main setting mode can be changed.
(Lock 3): All set values except input type can be changed. However,
they return to their previous value after the power is turned off because
they are not written in the non-volatile memory. Be sure to use
Lock 3 when changing the set value frequently via communication.
(When Lock 1 or Lock 2 is selected, if the value changed by the
communication function is the same as the previous one, it is not
written in the non-volatile memory.) Do not change any setting item
in Auxiliary function setting mode 2. If any item in the mode is changed,
it will affect other setting items such as SV and Alarm value.
