Dwell time in minutes

[JB7280]

Not MC related, but I am running a break-in procedure on a right angle head, and while I ended up just running it manually, it got me wondering, is there a way to set dwell time in minutes?  I tried writing a little program for the spindle to run at a set speed for 20 minutes, but it wouldn't handle that many digits.  I'm sure there's a way.  

 

fyi, it's a Fanuc GTech 31i

G4 X60. Is one minute

So g4x1200.

Crap!  I wasn't putting a decimal at the end so it was treating it as 60ms.  Stupid mistake.  Thank you

There's a parameter (#1015.7) that dictates behavior for dwell. Set at 0  = Depends on the increment System, set at 1 = does not depend on the increment system (always ms).

So decimal = seconds. No decimal = ms.

Does that affect only the dwell behavior, or does it affect feedrates and such as well?

Only dwell.
