7-5. Solenoid Valve for Clamp and Unclamp 

For Pneumatic Clamping, a solenoid valve is equipped inside. 

Please refer to the specification drawn in outside view and wiring diagram. 

 

【 

Excitation Unclamp Spec.

 

】

 

Solenoid: ON 

  ･･･

 Unclamp 

Solenoid: OFF

  ･･･

 Clamp 

【 

Excitation Clamp Spec.

 

】

 

Solenoid: ON 

  ･･･

 Clamp 

Solenoid: OFF

  ･･･

 Unclamp 

 

Since there is polarity in the pressure switch by SMC 

CORP., a proximity switch

、

and a solenoid valve, please 

refer to the wiring diagram. 

 

8. Mounting the Workpiece 

Securely mount the workpiece to the unit. If this is not done 

properly, it may cause severe injury and/or accident as well 

as poor indexing accuracy. 

 

Avoid mounting a workpiece which has poor flatness or 

perpendicularity directly to a table face. This may strain the 

table and prevent smooth rotation, which may result in very 

poor indexing accuracy. Shimming may be required to 

prevent this problem. 

 

Clamp the work in equipartition on the rotary table as much 

as possible.
