Hello Graham and all.
I'm from German and this is my first Post in this great Forum. I read your Posts to the Problem with the Spindle Drive.
I have the same Drive (it's an Lenze 534) on a Boxford 160TCL CNC-Lathe, it works with a Lenze DC-Motor 180 Volts.
I use Mach3 and i have the same Problem: How can i change the direction of the drive?.
I use this Board:
http://www.campbelldesigns.com/breakout-board.php and the Spindle Control
http://www.campbelldesigns.com/mach-spindle-speed-control.php. With the second Board i can control the
Spindle Speed with an analogue 0-10V input. It works well, but i have no Idea how to change the direction.
The Spindle Control Pcb have the same
N/O COM N/C pins like the DigiSpeedXL. Did i need two relais
with 24 Volts (one for Fwd and one for Rwd) ore can i do it with one relais? Please excuse my bad English and i
hope you understand what i mean. I have no Problems to read in English but it's difficult to writhe in English.
Best regards, Dietmar.
