Appendix 3: Password Functions; Parameter Reading And Writing Restriction Level - Johnson Controls Penn VFD68D Series Technical Bulletin

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.
