Chapter 3: Operation
Operation Notes
When using the AS-3901-B or AS-3901-C modules, observe the
following operation notes:
•
If you change parameters within 16 seconds after the AS-3901
banner first appears on the VFD, your changes will not be saved.
Parameter changes that you make after this 16-second delay will be
saved and restored if the module loses power and must be restarted.
• Although the effect of a parameter change may appear to be
immediate, the module requires 20 seconds to save the latest
change. If another change is made during these 20 seconds, the first
parameter change and the second parameter change will not be
saved until 20 seconds after the second parameter change. There is
no limit to the number of changes that can be made within 20
seconds of each other. However, none of these changes will be
saved until 20 seconds after the last parameter change.
• When you set the FctryRcl (factory recall) parameter to Yes , the
module takes several seconds to reset all of the parameters. ( Setup
parameters are not affected by this factory recall mode.) The lists of
“Operator and All List Parameters” on page 24 and “Tree View
Parameters” on page 41 indicate parameter default settings that are
restored when FctryRcl is set to Yes .
• With some parameters, certain changes will cause additional
changes in other parameters. See
page 22 for more information on
these cross-functional parameter changes.
Note
If you do not observe these
“Operation Notes,” you may
accidentally change your
parameter settings.
