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.
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
f268 settings
Each of the following numbers (89, 91, 93) are reverse signals.
