9.7 Interrupt Stop Operation
By the interrupt stop operation start command, the operation starts with operation speed I. After detecting the
rise/fall edge of interrupt input 0, the operation decelerates and stops. In addition, when interrupt input 0 is not
detected, the operation decelerates and stops at the 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 approximate S-shaped acceleration/deceleration, refer to Section 6.8.
→ For details on the STOP command, refer to Section 6.5.
1. Operation
1) It sets the operation speed I and the target address I.
2) When the interrupt stop operation start of the operation command is turned from off to on, the interruption
stop operation starts with operation speed I. (The positioning completion flag turns off.)
3) When interrupt input 0 is detected, the operation decelerates and stops. Turn on the positioning
completion flag to end the operation.
Point
When the travel amount is 0, the positioning operation is not executed even when the interrupt stop operation
start is turned on. In addition, the positioning completion flag also does not change. The READY turns off only
for an instant.
2. Address specification
Both absolute address and the relative address can be specified.
With absolute address specified: Specifies the distance from address 0.
With relative address specified: Specifies the travel amount from the current address.
3. Rotation direction
• With specified absolute address:
The rotating direction is determined according to the relationship between the current address and target
address I.
- Current address < Target address Ι: Forward
- Current address > Target address Ι: Reverse
