Functions
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 multi-
function 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.
