Using Intelligent Input Terminals
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 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). | See I/O specs on page |
|
•The minimum ON time of [UP] and [DWN] is 50 ms.
•This setting modifies the inverter speed from using F001 output frequency setting as a starting point.
