Title: Mach 3 enable
Post by: ABHELI on March 25, 2010, 09:04:35 AM: Hi All

Does Mach 3 have the capability to send an enable signal to my drive board. What I want is for my drivers to be powered down before and after I run a program. My drivers are a unipolar with power resistors that are always on. the boards do have an enable pin. the addition of 5 volts shuts the boards down. I searched the Mach settings and could not figure it out. Is it possible?

If you use them the drives will be disabled when you go into reset.

I knew about the enable /disable with the reset. Is it possible that when the program is finished that it will automaticly disable the drives

I tried the setting you suggested it did not work. do I need to configure an output port for this setting other than my enable pin.

thanks ABHELI
