Interrupt 2-speed Positioning
1.
Control requirements
y
Write K8 (H’8, i.e. b3 = 1) into CR#32 to enable interrupt 2-speed positioning
y
Set up 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)
