I am using the EES and PMDX-122 BOB, C6 Spindle Variable spindle control..
When I start a program, M3 closes the relay on the C6 Variable speed control board and Starts the spindle, the program runs. , When it is time for a tool change, M6 tells relay to open and stop spindle for the tool change.
The problem is, that when M6 tool change occurs, or M9 at end of program occur, the relay on the BOB stays energized, and spindle only slows down to 860 RPM’s
What is keeping the relay energized?
Thanks,
Toad
