Hitachi X200 Series instruction manual Remote Control Data Clears the Up/Down frequency memory

4−28

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).

See I/O specs on page 4–6.

•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.
