Here are the lines to look at from the Victor manual:
Quote:
Brake / Coast Guidelines:
1. Always install jumper to prevent loss. If you lose
the jumper, a standard computer jumper will work.
2. The Coast condition (Jumper on Inner two Pins) sets
the output to an open circuit during neutral.
3. The Brake condition (Jumper on Outer two pins)
sets the output to a short across the motor leads
during neutral.

If the jumper is missing, that is an open condition which means "Coast"
Note #1. It just says to install the jumper to "prevent loss" There is no functional reason to do so if you desire a coast configuration.
