Before starting on setup parameters, there is a parameter called LOC.
- 0: No key lock
- 1: May not change settings other than target values in the operation screen
- 2: May not change any parameters
- -1: If switching to the setup parameter setting screen, set "-1".
If setting the key lock (when LOC=1 or 2), if you set LOC to "-1" then parameter settings cannot be changed. Set "0" and press the SET/ENT key to clear the key lock. Next, set LOC = -1 again, and then move on to the setup parameters.
