Transporting work pieces from machine to machine for processing
High speed transport is possible (straight section: Max. 2,000 mm/s; curve section: Max. 1,500 mm/s).
Work pieces can be stopped at multiple locations (repeatability ±0.5 mm).
Soft starting and soft stopping are possible.
The combination of straight sections and curve sections allows you to create the pathway you want.
Pathwaycanbemodiedaftersetup.
Maintaining the conventional pathways, work pieces can be transported from machine to
machine.

• Transporting distance: 3200 mm
• Belt length: 6590 mm
Calculate the belt length based on the unit combination given above. (Refer to page 8 for details.)
1. The belt length for the motor drive unit and the tension unit is 1170 mm (xed length).
2. Double the stroke length of the straight section.
(stroke length of [ESM-ST-500] + stroke length of [ESM-ST-1000] + stroke length of [ESM-ST-300]) × 2
= (500 + 1000 + 300) × 2
= 3600 mm
3. Belt length for the 90-degree curve unit is 910 mm.
Since there are two of them, the total will be: 910 × 2 = 1820 mm
4. "Add the belt lengths obtained in steps 1, 2, and 3."
"Belt length for the motor drive unit and the tension unit" + "Double the belt length for stroke length of straight section" +
"Belt length for the curve section × quantity"
= 1170 mm + 3600 mm + 1820 mm
= 6590 mm
Hence, the belt length is 6590 mm
