Pulse Train Frequency Input; Pulse Train Frequency Processing Block - Omron 3G3RX User Manual

Pulse Train Frequency Input

This function allows you to use a pulse train input to the SAP-SAN terminals as frequency reference
or PID feedback value in each control mode.
(This function can be used in all control modes.)
Set the input frequency at the maximum frequency in pulse train frequency scale P055.
The analog input start/end function cannot be used. To limit the input frequency, use pulse train fre-
quency bias amount P057 and pulse train frequency limit P058.
