 This function is valid when the parameter (frequency setting mode selection) =  is set.
■ Input terminal settings
Assign the following functions to the input terminal, you can change (up/down) or clear the output frequency
by using the terminal's ON/OFF.
Input terminal function ON OFF
88 Frequency UP Frequency setting increase Clear
90 Frequency DOWN Frequency setting decrease Clear
92 Clear frequency UP/DOWN
OFF  ON: External logic up/down
frequency Clear settings
 settings
Each of the following numbers (89, 91, 93) are reverse signals.
