• With the specified relative address:
The rotation direction is determined by the sign (positive/negative) of the target address I and the target
address II.
- Target address Ι, Target address ΙΙ > 0: Forward
- Target address Ι, Target address ΙΙ < 0: Reverse
Caution
An abrupt change in the rotation direction may cause damage to the machine. It may also cause an error
through motor overload.
If the operation in a different direction requires stop time, use the 1-speed positioning operation.
Point
When the traveling direction to the target address I and target address II is not the same as shown below, the
motor decelerates and stops at the target address I, and then starts rotation in the reverse direction within 1
ms in the case of forward pulse/reverse pulse output or within 2 ms in the case of pulse/direction output.
• With the specified absolute address: When the relationship between "the current address and the target
address I" and "the target address I and the target address II" is different
• With the specified relative address: When the target address I and the target address II signs (positive/
negative) are different
4. 1-speed completion flag
• Conditions to turn on
- When the operation reaches target address I
- When the operation exceeds target address I during deceleration by an error or by STOP
• Conditions to turn off
- When the positioning completes
- When the operation stops by an error
- When the operation stops by the STOP command (only when the remaining distance operation is
invalid)
- When the remaining distance operation is cancelled (only when the remaining distance operation is
valid)
5. Positioning completion flag
The positioning completion flag turns off when the operation starts.
The positioning completion flag turns on when the operation reaches target address II.
