Spindle help to EDING CNC

[D-man]

The black wire appears to be linking the CM and FWD terminals, as well as providing a common feed (probably to provide the common for switching the inputs).

You'll have to go through the settings menu (F3.0 - Pg32 in the manual) to see what X1, 2, & 3 have been configured to do.
The TA/TC is an output, again you'd have to check the settings to see what it's set to (F3.8 - Pg 32 again).

I'm not sure what Eding outputs, but you may want to reconfigure the drive so it uses an analogue 0-10V input to set the speed.

OK Before i report with the Parameter settings i do know (thanks to google translate on the phone, AWESOME!), that the following wires were plugged into the old board for:

RED: spindle Low
GREEN: Spindle in
YELLOW: Spindle High
BLACK: was into 5v
