MP22 Star Robot Operational Update

We had a service tech from Star Automation in here yesterday on a courtesy call to help us out on some issues we have been seeing with the TW1200 robot on MP22.  Listed below are some corrections that were made that I wanted everyone to be aware of.

 

1)     Insert Arm L5 Home Limit Switch-

We were having an irritating problem with the robot not wanting to reference or return to the home position without the L5 Limit Switch being made.  Since we’re not currently using the Insert Arm, we corrected this by moving the L5 Limit Switch closer to the traverse beam and set the “Avoid Position” for the Insert Arm to 0.  Now the Insert Arm should never move off of the L5 Limit Switch and cause this problem.  Also because we moved the Insert Arm closer to the Traverse Beam, we were able to move the Product Arm Limit Switch closer to the Traverse Beam to give us more Crosswise stroke on the Product Arm.  Now we should not have to open the mold as far to remove parts.

2)     Part Grip Circuit-

The Part Grip circuit was not functioning because the robot’s previous owner had wired the valve output down to a plug at the EOAT.  The valve was rewired and now functions correctly.

 

Also, if you’re like me, then you have been having problems getting this thing to reference when you first power it up.  I would get an alarm saying “To make sure there is no interference with the Traverse Beam and to perform Posture/Rotate in Free Operation Mode”, or something like that.  What I learned yesterday about referencing the robot and homing the robot both is that it works a whole lot better to exit all the way out to the initial screen first before homing/referencing the robot.  There are two ways to home the robot-  First you can hold the “Dead Man” button until the bar at the top of the screen turns yellow and then hold the home button, or secondly you can turn the switch on the pedestal to “Origin” and then press the green “Start” button on the pedestal.  The light on the “Start” button will blink until homing operation is complete.

 

Call or email with any other questions.

Thanks
