6.10.4 Setting of frequency with the input from an external logic
 : External logic input - UP response time
 : External logic input - UP frequency steps
 : External logic input - DOWN response time
 : External logic input - DOWN frequency steps
 : Initial value of UP/DOWN frequency
 : Change of the initial value of UP/DOWN frequency
 Function
These parameters are used to set an output frequency by means of a signal from an external device.

● This function is valid when the parameter fmod (Frequency setting mode selection 1) = 5 is set.
■ Input terminal settings
Assigning the following functions to the input terminal will allow you to change (up/down) or clear the output
frequency by using the terminal's ON/OFF.
