I don't understand why you're mentioning pin 17. The charge pump uses O1, and page 28 of the AXBB-E manual shows O1 connected to a relay to disable power to the drivers.
So is this strictly an internal function of the board or do you have to wire a relay and a manual switch to it? In Mach its listed in the outputs, so do you just activate it there only and do not need a switch?
It is an internal function, so no external switch is required to trigger it.
If you're not already using O1 as a simple output, then you would configure the charge pump pins in Mach3 and disable Output 1. The relay on page 28 is used because the example turns off power to the drivers. It's one option for disabling the drivers, but not necessarily the only option.
If you are already using O1 for some other purpose, then you'll have to move that function to a different pin before you can use the charge pump function.
i am running open loop 32 bit dsp drivers.
That doesn't tell us very much.
