Functions
Operation Frequency Function
•Two systems of frequency reference operation results are available for the frequency reference
and PID feedback value.
Note 1: When this function is enabled, the Up/Down function cannot be used. In addition, frequency cannot be
changed through key operations from output frequency monitor d001, frequency conversion monitor
d007, or output frequency setting F001.
Note 2: The same setting is available in A141 and A142.
•To use this function as a frequency reference, set frequency reference selection A001 to "10".
•To use this function as a PID feedback, set PID feedback selection A076 to "10".
Frequency Addition Function
•The value set in frequency addition amount 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.
The A145 value is added or subtracted with the ADD terminal turned on.
Note 1: If the sign of the frequency reference is changed ((-)  (+), or (+)  (-)) as a result of operation, the
rotation direction will be inverted.
Note 2: When the PID function is used, the frequency addition function is enabled for a PID target value.
(Note that A145 is displayed in % (in increments of 0.01%).)
