11. ZRN device
******************************************************************************************************
The contents of this item are unnecessary for the NC rotary table of Kitagawa's controller
spec. and 4th axis spec. which don't have a dog for ZRN deceleration.
Machine zero position of this unit which set at shipment from factory is memorized due to
the specification of servo motor with absolute encoder. Accordingly this unit does not have
machine zero position device like as proximity SW and Dog. When changing machine zero
position, instruction manual of controller (article for setting of machine zero position) would
be referred.

11-1. ZRN device on table
The ZRN device rotates clockwise (CW) on the standard specification.
The table datum groove comes to position at a right angle to the motor when connected to
the NC unit. The dog, which activates the table speed reduction, is located inside the unit.
The ZRN deceleration dog is mounted in the table and it can be mounted on the optional
position of outer periphery. When shipping a product, the flank of the guide block fitted on
the table has been positioned parallel to 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.
11-2. ZRN device Adjustment [See Fig.4]
When the zero position is changed or when the rotation direction for return is changed to
counterclockwise, adjust the ZRN position through the following procedures.
1) Remove the flange plug
①
located on the top surface of the NC Rotary Table.
2) Rotate the table and, thorough the hole made by removing the hexagon socket flange
head screw plug
