9.8 Interrupt 2-speed Positioning Operation
By the interrupt 2-speed positioning start command, the operation starts with operation speed I. After
detecting the rise/fall edge of interrupt input 0, the operation speed changes to operation speed II. Then, after
the rise/fall edge of interrupt input 1 is detected, the operation decelerates and stops at target address I.
→ For change of the operation speed, refer to Section 6.6.
→ For change of the target address, refer to Section 6.7.
→ For details on the STOP command, refer to Section 6.5.
1. Operation
1) Set operation speed I, operation speed II, and target address I.
2) When the interrupt 2-speed positioning operation start of the operation command is turned from off to on,
the interrupt 2-speed positioning operation in operation speed I starts. (The positioning completion flag
turns off).
3) When interrupt input 0 is detected, the speed changes to operation speed II.
4) When interrupt input 1 is detected, traveling is executed for the amount set to the target address I with
operation speed II, and the operation completes by turning on the positioning completion flag.
Point
• When interrupt input 1 is detected before interrupt input 0 is detected, interrupt input 1 is ignored.
• The current address is cleared by interrupt 2-speed positioning operation start command. After detecting
interrupt input 1, the current address starts changing.
• When the travel amount is 0, the positioning operation is not executed even when the interrupt 2-speed
positioning operation start is turned on. In addition, the positioning completion flag also does not change.
READY turns off only instantaneously.
