Stuart,
The GV3000 drive plate shows V6.04 but when I checked P.098 it shows V4.42.
I downloaded Manual D23323 from Reliance and the parameters for V4.42 do not include

Brrrrrr...

I do not have a P.054 in remote or local. The parameters skip from P.051 to P.060.
Must read the manual and find out why.
