Appendix 3: Password Functions (P.296, P.297)
Registering a four-digit password can restrict parameter reading and writing. You can set these parameters
when P.160 = 0.
Note:
When P.296 is set to something other than 9999, then P.297 is always available to enter a password,
regardless of the setting for P.160.
Parameter Reading and Writing Restriction Level
P.296 controls the level of reading and writing restriction.
