I'd allow myself to re-ask the same questions here:
Generic question. regarding this controller. If it is supposed to work
close to DVCS, etc. Does ramp controller need any programming when
changing speed and/or APC voltage?
Is it necessary to turn ramp on and off during the runtime?
No, it's a set-and-forget type of programming. Turning that on/off during
runtime is self-managed and, after the initial setting that this driver,
no further action is required - or at least not from Linux.
Cheers!
Angelo
