Sumitomo Drive Technologies Cyclo 6000 - 5. COUPLING TO DRIVEN MACHINE; 5.1 Check Direction of Rotation; 5.2 Mounting Connector

•
Conrm the rotation direction before coupling the unit to the driven machine. Incorrect rotation
direction may cause personal injury or damage to the equipment.
•
When operating the product alone (uncoupled), remove the key that is temporarily attached to the
slow speed shaft; otherwise the key could fall o resulting in injury.
•
Cover rotating parts; otherwise, it may result in injury.
•
When loading the unit and the unit is coupled with pulleys, check that the centering, the belt
tension and parallelism of the pulleys are within the specied limits. When the unit is directly
coupled with the driven machine, check that the direct coupling accuracy is within the specied
limits. When a belt is used for coupling the unit with the driven machine, check the belt tension.
Correctly tighten bolts on the pulley and coupling before operation; otherwise, it may result injury
or damaged equipment due to misalignment.

5.1 Check Direction of Rotation
5. COUPLING TO DRIVEN MACHINE
When wiring is performed as shown on Pages 27 to 30, the motor shaft rotates to the right as seen from the Low
Speed Shaft side. In the following diagrams, arrows show the direction of slow speed shaft rotation in this case.

•
When mounting a connector to the unit, do not apply impact or excessive radial and/or axial load to the shaft.
The bearing could be damaged, or the collar could come o.
•
Interference t is recommended for slow-speed shafts.
