1-speed Positioning Operation

By the 1-speed positioning operation start command, the operation starts at the operation speed I, and the
operation decelerates and stops at target address I.
→ For details on the approximate S-shaped acceleration/deceleration, refer to Section 6.8.
1. Operation
1) Set the operation speed 1 and target address 1.
2) When the 1-speed positioning operation start of the operation command is turned from off to on, the 1-
speed positioning operation in operation speed I starts. (The positioning completion flag turns off.)
3) The operation decelerates and stops at target address I. The positioning completion flag turns on, and the
operation ends.

Point
When the travel amount is 0, the positioning operation is not executed even when the 1-speed positioning
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 specification is possible.
With absolute address specified: Specifies the distance from the address 0.
With relative address specified: Specifies a travel distance from the current address.
3. Rotation direction
• With absolute address specified:
The rotation direction is determined according to the relationship between the current address and the
target address I.
- Current address < Target address Ι: Forward
- Current address > Target address Ι: Reverse
• With relative address specified:
The rotation direction is determined by the sign (positive/negative) of the target address I.
- Target address Ι > 0: Forward
- Target address Ι < 0: Reverse
