| Have a Xylotex XS-3525/8s-1 (Single axis controller card, one for each axis.) Pin No. 9 VCC (shown in drawing with a "?") is described as Logic Power Supply (+5V). Does this mean that I need to apply +5V at that point? Is there any meaning to "VCC"? Thanks |

| Gary is incorrect. You supply 5V to the VCC pin, and the ground from the 5V supply needs to go to the first pin labeled Gnd, where you have labeled 2. This is required to power the board. The top right of the data sheet says that: A single 9 pin Molex header contains all of the logic signals necessary to operate the drive 1) GND Logic Power Return (Ground) 2) SLEEP# Shuts down entire drive 3) MS1 Sets up microstepping mode. See Table Below Left 4) MS0 Sets up microstepping mode. See Table Below Left 5) HOME# Motor Position Indicator 6) ENA# Disables Motor drives. 7) DIR Motor Direction Signal 8) STEP Motor Step signal 9) VCC Logic Power Supply (+5V) The MS0 & MS1 inputs may also be selected via onboard umpers. The ENA# input may also be enabled via an onboard umper. The minimum connections would be GND, STEP, DIR, and VCC. See schematic (last page) for actual onnection assignment. Also: Logic Requires < 50 mA at +5.0V on the 9 pin Molex connector

| The newer boards get there 5V from the motor supply through a built in converter. The older boards needed a seperate 5V power supply to run the boards.

Thanks Gerry. This puts me one step closer to spinning these motors. In trying to understand the Pinout information provided by Xylotex, how did you know it should be +5V going in. Does VCC indicate a voltage going into that pin? |

| See above 9) Logic Power supply (+5V) I have one of these boards, but mine gets power from the 3 Axis I also have.

| I understand that Pin 9 requires that +5 V be applied to that pin, in my situation. My below question doesn't have anything to do with the current board I am working on, just trying to understand some simple (or not so simple) electrical terms: What is the definition of "VCC"? If I see that on another wiring diagram, will it always indicate voltage going in? And what is the definition of "VBB"? Will this always indicate voltage going out? Thanks Gerry Hager |
