RE: MTS/Instron Load Frame Controller IOCs

[Tom Willemsen - STFC UKRI via Tech-talk <tech-talk at aps.anl.gov>]

Hi,

 

We have EPICS support for Instron 8800 load frames in two flavours: NI-GPIB for an older-style controller [1] which is almost certainly no longer manufactured, and via Arby.dll for a newer-style controller [2].

 

These controllers have a reputation at our facility for being somewhat fickle in terms of communications. The arby.dll approach [2] depends on a 32-bit Windows EPICS IOC with manufacturer software running in the background.

Please get in touch if you need further information.

Subject: MTS/Instron Load Frame Controller IOCs

 

Hi everyone,

 

Thanks for all your help so far, you’ve been fantastic!

 

Our facility is looking to implement a universal testing frame at one of our beamports, and we are looking to acquire an MTS or Instron load frame controller to control the motors on the frame. Are you folks aware of any IOCs/support modules that have been written for these controllers?

 

Suggestions for other kinds of epics-compatible controllers that would work for the purpose of driving these motors are also welcome!

 

Motor Specs:

Parker RX320E

DC Brushed Servo-electric motors

Permanent Current: 7.8A

Supply Voltage: 54V

Peak Current: 20A

Maximum Speed: 3000rpm

 

Thanks,
