Thanks Lewis.
The version strings are the same "MM4006X Controller Version 6.03b date
02-18-2002"
Also the MSTA field is false only for the first axis of that controller.

Hi, Xiaoqiang.
Are the firmware versions of the three controllers the same?
I had a problem a while back with the Mclennan PM304 motor module driver
where it wasn't working right. The problem turned out to be that the
status bits from the controller had different meanings for different
firmware versions (motorApp/MclennanSrc/drvPM304.cc).
