the ATV 312 worked perfectly. sans programming software and manual
their 320 replacement doesn't. can't follow a 1.27 sec decl ramp.
customer is against ABB and AC Tech.
Any suggestions?
 
From your post, I gather that the ATV312, software and cables worked.
you now have an ATV320 replacement.
Can you manually program it and does it work?
is there a new software version and software drivers?
different interface cables?

have you tried installing the software on another pc?

just making suggestions based on experience and hope this helps.
