MK Products COBRATURN Rotary Adapter Installation Tips


When using the MK Products COBRATURN Rotary Adapter Kit you will be able to control the rotation of the COBRATURN positioner using a simple plug-and-play adapter.

Kit Contents

  • ASM-1103 Adapter, MK Products COBRATURN T-260/T-30 Positioner

  • 6’ Ethernet Cable

  • 1m M8 3-pin cable

  • 1m M12 5-pin cable

  • Photoelectric sensor, adjustable

Connecting the Adapter to the Positioner

Using the supplied Ethernet cable you can plug the adapter into the positioner at the same port where the foot pedal would plug in. On the adapter plug the cable into the port labeled Rotary Unit. If you want to continue to be able to use the foot pedal plug it into the port labeld Foot Pedal

Connecting the Adapter to the Robot

Using the supplied 5 pin cable, connect the cable to the port on the adapter labeled Robot and then connect the other end into one of the (4) IO ports on the side of the robot cabinet. The Red port is the default port that is used in the Rotary Weld step in the Beacon Welding application but any of the 4 ports can be used and then just selected when setting up the weld. You can connect up to (4) rotary positioners to the robot.

Connecting Sensor to Adapter

In the KIT-1108 is a photoelectric sensor that has an adjustable sensing range using the small screw that is on the sensor you can adjust the range of detection. This sensor will be used to determine when the rotary has rotated the full 360 degrees. Most customers simply add something to the rotary table that the sensor can use to detect the rotation point. You can see in the image below that the customer added a long bolt in one of the table slots and then the sensor is picking up that bolt when it revolves. The red spot on the bolt is from the sensor.

To connect the sensor simply plug the supplied cable into the sensor and then to the adapter at the port labeled Sensor.

You can adjust the sensing range of the sensor using the screw as shown in the image below. The two LED’s will turn on when the sensor is detecting an object, the amber light turns on when the sensor initially detects and the green LED turns on when the sensor fully detects the object. The output from the sensor will turn on as soon as the amber LED is triggered.

You have now completed the installation of the KIT-1108 MK Products COBRATURN Rotary Positioner Adapter Kit.
