Pushing operation 

The table move to the target position and hold a work piece with the set pushing force. 
The figure shows setting items and operation.The setting items and values are described below. 
 

< Confirmation of reaching the target value during the pushing operation> 

The 

“target position reaching signal” INP (in position) is generated when the target pushing force 

(Trigger LV) is achieved. 
Also, if the actual pushing force exceeds the Trigger LV, the INP signal is turned on.   

 
 
 
 
 
 
 
 
 

 

 
 
 

 

 
 
 

 

 
 
 
 
 
 
 
 
 
 
 

 
 
 

 
 
 
 
 

 
 
 
 
 

Caution 

When the table is to be 

stopped by an external object, utilize the “pushing operation”. 

If  the  product  is  used  in  the  positioning  operation,  there  may  be  galling  or  other  problems  when  it 
comes into contact with the external object. 

 

Note) When it is not possible to operate the table, move it with manual override screws.
