"Diff Code Type" Error Message

"Diff Code Type" Error Message

A "Diff Code Type" error message may pop up when trying to copy parameters from the LCD keypad (loader) into the VFD. The error means that the parameter backup was read from a VFD with different firmware than the VFD we are trying to write to.  Check CNF10 to verify version matches.

Example:
A copy keypad operation cannot be performed between a VFD with firmware 1.00 and another VFD with 1.20.
