Industrial Control System

All,

Please note that the content of the attached e-mail.

The effect of this (for firmware versions V1.30, and later) is that the
HOME flag is 'lost' when in PSE or PSM mode when the QA and EA commands
are executed as a pair (as done in the ALL_INFO message) in drvMAXv.cc,
lines 101, 304. And the problem code is at lines 643...645, where the
HOME flag gets over-written with a ','.

Austen,

The investigation revealed that all our command responses terminate with
a <LF> (0x0A). There is no tailing NULL.

 

In FW 1.29 and older a bug added a NULL after the <LF> for the commands
RA, QA, EA and RL.

In FW 1.30 and newer this NULL was removed for RA, QA and EA.
Unfortunately the RL command has still that problem. We intend to fix
this for the next firmware release.

 

I am not sure if this connects to your original problem of not seeing
encoder at home. Have you hardwired the encoder signal and issued the
query?
