General Mach Discussion / Step Active Low works, board specifies Active High
« on: October 29, 2014, 05:22:10 PM »
I am converting mill that has a MN400 driver board to a parallel board. Everything seems to be working great, however, I had to set the motors step signals to Active Low. The board specifies Active Low.
The board I'm using is a DM8010
http://microkinetics.com/pdfmanuals/DM8010.pdf
From the manual:
Step input signal ............................................... TTL compatible positive edge trigger
And:
Step - used to step the motor. The stepping frequency range is from 0 to 300
KHz. The driver updates the motor position after a LO-to-HI transition
occurs. The minimum pulse width (LO level) should be 2uS
Should I worry or try to correct this. TIA
