5-6 Operation Functions
5
Frequency Addition Function
The value set in Frequency Addition Amount Setting (A145) can be added to or subtracted from the selected frequency reference value.
To use this function, allocate "50: ADD" to any of the multi-function inputs.
A145 is added or subtracted with the ADD terminal is turned on.

Note 1: If the sign of the frequency reference is changed (( −) → (+), or (+) → (−)) as a result of operation, the rotation direction will be reversed.
Note 2: When the PID function is used, this function is also enabled for a PID target value.
(Note that A145 is displayed in % (in increments of 0.01%).)
Remote Operation Function (UP, DWN)
This function changes the Inverter output frequency using UP and DWN terminals of the multifunction input terminal.
Allocate "27: UP" and "28: DWN" to Multi-function Input Selections (C001 to C007).
While the UP/DWN terminal is turned ON, the acceleration/deceleration time conforms to
F002, F003/F202, and F203. Switch between Controls 1 and 2 using the SET terminal which is a multi-function input terminal to which "08: SET" is allocated.
Also note that if "01: Store frequency data" is selected for C101, the set frequency value after
UP/DWN adjustment can be stored when the power is shut off.
