Probably tachometer....

The W doesn't seem to stand for anything, "Drehzahlsignal" meaning
rotation count signal is completely W-free. But then a couple of
manufactureers use "61"
for the "L"-amp connection...

They're probably entirely arbitrary designations so I wouldn't bother
pursuing any further the idea that German translations of F for field and
G+ for Generator output terminal and the like will answer your question
any better than what's been arrived at in this thread by the usual
'detective/educated guesswork'. :-)
