Aluminium Profile Type Router - Initial questions

[AndyUK]

Vfd powered up on bench to check settings, most were factory set, such as 400 frequency and earth pin connected to body .
Quick question on pd007 , factory is set to 0.5 and 1.2 recommended , minimum frequency . Can anyone confirm this is correct as some forums etc use very different values here.
Spindle is a gdz80 2.2
Thanks

I use 1.2 on my 2.2kW 400Hz generic Chinese water cooled spindle.

Ignore the below sentence, I was remembering information about PD011, which is similar. Might still be the reason?
I believe the variation on this one is between if its water or air cooled. You shouldn't run the air-cooled version below a certain RPM (i'll probably miss quote it here if I try to remember) without it overheating, so that might be the cause of the variation in recommendations you see.

One thing Jazz recommended when he saw my settings which were mostly coppied from the sticky, was to increase the acceleration and deceleration times, PD14=5 PD15=10.
