Third party software and hardware support forums. / Mach with a CNC4PC C19 frequency converter

« on: June 11, 2008, 11:06:41 AM »

Hi,
I have a frequency converter that I have purchased to control my router speed.
It is wired and configured as far as I can tell.
I am using a C11 BOB.
When I give a speed in Mach and turn on the spindle the LED for the  pin (#3) comes on so I think I am getting a signal.
I am trying to use PWM mode.
I have 120volts at my plug at this point.
I have a hand drill hooked to my plug to test this setup.
When I try to run the drill the voltage drops to zero at the plug.
No matter what speed I put into Mach the same thing happens.
Does anyone have an idea what I might be doing wrong?
When I go to the diagnostic screen in MACH it shows the output pin (#3) pulsing but not staying on full time.
Please help, I have been messing with this for several days and am having NO luck.
Thanks,
BigB

FAQs / Is 23655 pulse per second fast enough?

« on: February 02, 2008, 10:05:05 PM »

Hi,
 I new to Mach 3 and have a question.
I just put together a dedicated computer to run the Mach 3 program.
It is a Dual Core 2.3G processor with 1G of DDR2 667 ram.
The only thing running on the computer is Windows XP.
When I run the driver test the pulse per second is steady at 23655.
I read in the manual that I needed 24500.
Will this difference hurt me?
I have yet to hook my driver board up because of this speed difference.
Any help will be greatly appreciated.
