Have any of you fine users run into a problem of a PIDA controller  not 
pushing to reach the setpoint?  This has occurred a few times recently  on 
newly 
configured (copied) PIDA blocks where no matter what I do, the  controller acts 
as though it has a setpoint deadband, and doesn't try to zero in  on the 
setpoint.  This is with MODOPT of 4 or 5, with SPLLAG at 0 or 1;  after 
deleting/undeleting the block; running the INT down to ridiculously low  
values, etc.  On 
Windows/MESH, I/A 8.2 using ZCP270's and FCP270's.   Any ideas?
