This is a Four axis micro-stepping bi-polar PWM current regulated stepper motor driver. It can be configured to
deliver up to ±2.5 Amps/phase up to a maximum of 35 Volts (including BEMF)
Each axis is independently jumper selectable to operate in either FULL, HALF, QUARTER or EIGHTH step modes. For
a typical 1.8° (200 spr) stepper motor, this means up to 1,600 steps per revolution (16,000 steps per inch
if driving a 10 tpi lead screw). The drive is shipped in 1/8th step mode. Additional jumpers required if lower
resolution wanted. Use this board for a 4 axis system, or a 3 axis system where you may want to add a fourth later
(it is OK to just have three motors hooked up).
Each axis has a potentiometer to allow maximum motor current drive adjustment.
The on-board IDC header accepts standard 26 pin IDC connectors for easy connection to IDC DB25 male connectors
which can be directly connected to a PC's parallel port to drive the boards STEP and DIRECTION input signals. Other
unused parallel port pin signals are routed to screw terminals for possible off-board use. (DB25 pin use -- (2) Step X (3) Dir X (4) Step Y (5) Dir Y (6) Step Z (7) Dir Z, (8) Step A, (9) Dir A (18-25) GND)
Each axis has an ENA# pin to allow enabling/disabling of the motor current-drivers.
PLEASE NOTE: Althought the driver board does provide unmodified/unbuffered
access to the unused parallel I/O through screw terminals, the board plays no other role in handling of home/limit
switches, E-STOP, or Spindle/Coolant relay control, etc. If you want a break-out board, look here:breakout
boards under hardware. To see a possible method of connecting switches to a drive board, look at the top of this
Please Read the DATASHEET for
These drive boards are Fully Assembled and Tested.
If you have more questions regarding
using the board with your application: Contact Xylotex
Before using the device, the potentiometers must be set for proper current output, which requires the use of your
voltage/multimeter! When running at High Current (generally 2.0A/phase or above), convective cooling (fan) required.
You get: XS-3525/8S-4 & the
IDC26-DB25 cable (IDC26-DB25 Cable is NOT a Parallel port Extension cable, it connects
the board to one though)
