Negative driving MX80L motor with ViX250IH

Alistair Newcombe
By  9 months ago

Hi,

Im attempting to use a Parker MX80L with a ViX250IH motor driver. Im interfacing it via LabVIEW by sending commands over the serial port. This was working fine for a period of time, but randomly the drive started to throw out an error when i attempted to drive it in the negative direction. I replicated this error when sending commands with the Easi-V software. 

Without any modification of the drive this error fixed its self, and then came back again. I've attempted to reset the drive setup a number of time, but this doesn't appear to have done anything. When I run the "Drive 1: Status" command I sometimes get an Error (PE) appearing, currently it is error code -1. Additional the user fault bit number 13 is set high ("End of travel limit hit"). 

I have successfully control the drive previously using the displacement control. Since I want to use this drive for preforming cyclic testing up to a specific position, I can only use displacement control.

Is there any easy method that can be used to fix this issue. There is another motor driver in my lab, which I might be able to borrow to see if the issue is with the driver.

Thanks for you help.

    The end-of-travel limits are normally closed and thus if you had an intermittent/loose connection for the limit sensor this could cause this symptom. A normally closed sensor is grounded (voltage low) and when active is voltage high, the same as an open connection. Can you check the connection?  Check the connector for bent or broken pins connecting into the ViX or any contamination inside the connector, and that the thumbscrews for the cable are tightened. 

    We can repair the MX80L stages. If you contact your local Parker ATC distributor with the model number and serial number, they can setup a repair Return Material Authorization (RMA) for the stage. If you don't know your local ATC or this was on a machine purchased, our ATCs are listed on our website here:
