Program Description
y
Read CR#33, #34 (current position) and CR#35, #36 (current speed).
y
Write K1 (H’1, i.e. b0 = 1) into CR#32 to set up the single-speed positioning mode.
y
Set up CR#23, #24 (target position) and CR#25, #26 (operation speed V(I)).
y
Set up CR#12 ~ #19 to complete the parameter settings for zero return.
y
When X0 = On, write K256 (H’100, i.e. b8 = 1) into CR#31 to enter single-speed
positioning mode.
y
When X1 = On, write K64 (H’40, i.e. b6 = 1) into CR#31 to enable the zero return.
y
When X0, X1 = Off, stop all the executions and set the current position to 0.
