Troubleshooting error messages

 

 

About this topic

The following tables list commonly encountered error messages, the causes of the errors, and ways to resolve the errors.

If you are still experiencing problems with the Labware MiniHub after trying the solutions, or if an error not on the list is displayed, contact Agilent Automation Solutions Technical Support.

For protocol-related errors, see the applicable automation control software user guide, such as the VWorks Automation Control User Guide.

Communication errors

The following error messages are caused by communication problems:

•	The command timed out.

•	Attempted to communicate without being connected, please connect and retry the operation.

•	Failed to connect.

•	TCP connection has not been established.

Check the following causes and try the corresponding solutions:

 

Cause	Solution
The Ethernet cable is not connected properly.	Verify that the Ethernet cable is in good condition and securely connected. Power cycle the device, and try to reconnect.
The device profile specifies the wrong device ID for this Labware MiniHub.	Verify that the device profile specifies the correct device ID. See Creating Labware MiniHub profiles. Reinitialize the profile. If the problem persists, power cycle the device.

Motor control errors

The following error messages are typically caused by an obstacle in the path of the Labware MiniHub rotation.

•	Axis timed out during commutation.

•	Axis timed out during homing.

•	Homing failed and the number of retries has been exceeded.

•	Motor has gone over I2T current limit either by a spike or for a length of time.

•	Move timed out.

•	Position is outside its limit range.

Check the following causes and try the corresponding solutions:

 

Cause	Solution
An obstacle outside the Labware MiniHub is preventing it from rotating.	Remove any obstacles that are preventing the Labware MiniHub from rotating. Try rotating the Labware MiniHub again.
The labware is not properly seated in the alignment features of the shelves and is preventing the Labware MiniHub from rotating. The robot teachpoints might be set incorrectly, the Labware MiniHub has moved after the teachpoints were set, or the shelves are bent.	Verify that all labware are properly seated within the alignment features of their respective shelves. Check for and replace bent shelves. Check the robot teachpoints at the Labware MiniHub to ensure that the robot is placing the labware in the shelves correctly. See Setting robot teachpoints. Retry the operation.
