3.6 I/O Link β MANUAL HANDLE INTERFACE
Overview
This function controls manual handle feed for FANUC servo unit β
series with I/O Link option ( I/O Link β) by using a manual pulse
generator on the host (CNC). Pulses from manual pulse generator are
transferred from the host (CNC) to I/O Link β through I/O Link. Still
further, this function can control the magnification of pulses by
changing the parameter. This function is available on the peripheral
control interface.
Explanation
After the manual handle mode of I/O Link β
(MD1(Y0#0)=0),MD2(Y0#1)=0,MD4(Y0#2)=1)is selected, the
host informs the magnification of the manual handle generator
(MP1(Y7#4),MP2(Y7#5)), and changes the manual pulse counter.
After reading the varied amount of the manual pulse counter, I/O Link
β operates the motor.
Actual pulses are that calculated pulses multiplied by the parameter
(No.10809-10811).
CAUTION
Please be sure to transfer 16 bytes signals from the
host (CNC) to I/O Link β.
