Single-speed Positioning
1.
Control requirements
y
Write K1 (H’1, i.e. b0 = 1) into CR#32 to enable the single-speed positioning.
y
Set up CR#23, #24 (target position) and CR#25, #26 (target speed).
2.
Devices
y
X0 = On: software starts (and stops after the target position and operation speed
are reached)
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 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).
y
When X0 = On, write K256 (H’100, i.e. b8 = 1) into CR#31 to enter the
single-speed positioning mode.
y
When X0 = Off, stop the execution of single-speed positioning.
