DGII series < Standard > equipped with closed-loop stepper motors αSTEP AR series
Both the rotary actuator and the motor unit use high-performance products.
The Closed-loop Type has excellent performance in load capacity, rigidity, and accuracy, and can be used for a wide range of purposes.
●Maximum Permissible Torque: 50 N・m
●Maximum Permissible Axial Load: 4000 N
● Repetitive Positioning Accuracy ±15 arcsec (±0.004°)

Structure of Closed-loop Type

High Power and High Rigidity

The hollow output table is integrated with a high rigidity cross-roller bearing.
< Rigidity >
Maximum Permissible Axial Load: 4000 N
Maximum Permissible Moment: 100 N・m
The permissible moment increases as the frame size increases, but the displacement caused by the load moment decreases.
< Output >
Maximum Permissible Torque: 50 N・m

High Positioning Accuracy with Non-Backlash

・ Non-Backlash
・ Repetitive Positioning Accuracy ±15 arcsec (±0.004°)
Note* The repetitive positioning accuracy is measured at a constant temperature (normal temperature) under a constant load.

Large-Diameter Hollow Output Table

Equipped with Closed Loop Stepping Motor Unit αSTEP AR Series

The DG Series Closed-loop Type comes equipped with the motor unit of the AR Series. This type uses the same control method as the AR Series, so the same drive and maintenance methods can be applied during startup. The built-in positioning function type, , can be connected to a network or multiple axes.

Energy Saving

Reduced Generation of Heat, Continuous Operation Possible

Alarm Signal Output in Case of Abnormality

If an overload is applied continuously, an alarm signal is output. When the positioning is complete, an END signal is output. This ensures the same level of reliability achieved by a servo motor.
