7.4.4.2 Example 2: Home Return in a Backward Direction (-)
When XA (XA_bGoHomeStart_CH0) turns to TRUE, pulses are output from CCW output Y1
of the specified channel 0 and the return to home begins. When X0 (X0_bNearHome_CH0)
turns to TRUE, deceleration begins, and when X2 turns to TRUE, home return has been
completed. At this point, the elapsed value area (sys_diPulseChannel0ElapsedValue) is
cleared to 0. (Y1 and X2 are used implicitly by
F171_SPDH .)
The wiring diagram shown above applies to this program. See page 137.
