The left limit switch for CH0 (Y0, Y1) is X5; the left limit switch for CH1 (Y2, Y3) is X7.

Reverse pulse output direction
M1305
M1306
4. When
D
is specified as Y0, its direction signal output is Y1; when
D
is specified as Y2, its
direction signal output is Y3.
5.
When the instruction executes, the pulse output starts in the reverse direction. The ELC then
controls the direction based on the limit switch and DOG switch. The current position of the Y0
output: (D1030,D1031); current position of the Y1 output (D1032, D1033)
6.
When the pulse output reaches the zero point, the pulse output execution complete flag
M1029 (CH0), M1102 (CH1) is ON and the register indicating current position is reset to 0.
7.
When DZRN instruction executes, external interrupt I40x (Y0) or I60x (Y2) in program will be
disabled until DZRN instruction is complete. Also, if the left limit switch (X5 / X7) is enabled
during instruction execution, external interrupts will be disabled as well.
