4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used 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 frequency bias amount P057 and pulse train frequency limit P058. •This function requires the PG Board (3G3AX-PG01).
