Hollow structure
 The wirings and pipings for rotating components are made easy by having the hollow in large diameters.
|
|
|
High precision
 Realizes a high precision of ±0.005 degree by adoption of grinding type hypoid gear and high resolution(0.0015～0.0007 degree/P) encoder.
Also usable as index table where a high precision was needed.
|
|
|
Multiple rotative motion
 The maximum operatable motion range(※) can be ±9999 degree from origin.
Unlimited rotative motion, which continuously rotates against a single direction, is enabled.
(※Vary through models)
|
|
|
High rigidity
Realizes a high rigidity by adopting large diameter table and cross rollers for the main guide bearing.
The 3 types of body can be selected from small/middle/large size.
|
|
|
No origination required
Absolute encoder types, which does not require originations, are lined up.
Even if it stopped by emergency stops, it can start its motion from the same position.
|
|
|
Built-in brake(optional)
Brake equipped specification is selectable on option, enabling preservation of arms and table positions whenever the power source was turned OFF, or in an emergency stops.
