2-speed Positioning
1.
Control requirements
y
Write K4 (H’4, i.e. b2 = 1) into CR#32 to enable 2-speed positioning.
y
Set up CR#23, #24 (target position I) and CR#25, #26 (target speed I).
y
Set up CR#27, #28 (target position II) and CR#29, #30 (target speed II).
2.
Devices
y
X0 = On: software starts
y
X0 = Off: stop the execution (controlled by the software)

Program Description
y
Read CR#33, #34 (current position) and CR#35, #36 (current speed).
y
Write K4 (H’4, i.e. b2 = 1) into CR#32 to set up the 2-speed positioning mode.
y
Set up CR#23, #24 (target position I) and CR#25, #26 (target speed I).
y
Set up CR#27, #28 (target position II) and CR#29, #30 (target speed II).
y
When X0 = On, write K256 (H’100, i.e. b8 = 1) into CR#31 to enter the 2-speed
positioning mode.
