It is possible for the inverter to retain the frequency set from the [UP] and [DWN]
terminals through a power loss. Parameter C101 enables/disables the memory. If
disabled, the inverter retains the last frequency before an UP/DWN adjustment. Use
the [UDC] terminal to clear the memory and return to the original set output frequency.

This feature is available only when the frequency
command source is programmed for operator
control. Confirm A001 is set to 02.
•
This function is not available when [JG] is in use.
•
The range of output frequency is 0 Hz to the value
in A004 (maximum frequency setting).
Example (default input configuration shown—see
