The rotational direction for ZRN is 
clockwise (CW). 
The dog for ZRN deceleration is mounted 
under the table and it cannot be found 
except when the dog position is adjusted. 
Though the dog can be mounted on the 
optional periphery position under the 
table, the table reference slot has been set 
so that it is parallel for the reference plane 
for vertical installation. 
Fine adjustment of the ZRN position may 
be required at the customer at the time of 
interface with the NC controller of the 
machine.
