Chapter 4 Explanation of Functions

4.2.13 Frequency addition function

The frequency addition function allows you to add or subtract the value specified as the frequency to be added (A145) to or from the frequency value of a selected frequency command.

To use this function, assign function "50" (ADD) to an intelligent input terminal.

When the ADD terminal is turned on, the inverter performs the addition or subtraction of the value specified as "A145".

Note 1: If the sign of the frequency value in the frequency command changes from minus (-) to plus (+), or vice versa, as the result of frequency addition, the motor operation direction will be inverted.

Note 2: When the PID function is used, the frequency addition function can apply to PID target data. (In such cases, the data display by function "A145" is in percentage [in steps of 0.01%]).
