Protect Parameters with a Password
Factory parameter values are password protected using Parameter F.000
(setting password). But, even after the password has been set, some factory
parameters cannot be modified. Such parameters must be set after operation
has stopped.
Parameter F.018 (version information) is a read-only parameter, and therefore,
cannot be modified.
Display and Change Parameter Values
To display or change parameter values, the operation panel must be in Program
mode. Use the procedure described in the following sections to change
parameters in Program mode. For calling out the error log and resetting faults,
refer to
