Page 7: Io6 General Description
IO6 General Description MachMotion’s IO6 breakout board provides a flexible, plug-in-play interface for CNC controls using PC based parallel port control software. The breakout board interfaces to the servo drives and spindle relay outputs with RJ45 mod jacks and Phoenix screw terminals for flexibility. -
Page 8: Description Of The Interface Assemblies
Description of the interface assemblies 1. Charge pump circuit and enable signals When there is no E-stop condition and the Mach3 software based control is running properly, Mach3 outputs a steady pulse stream to the IO6 breakout board. The IO6 receives this pulse stream and sends an enable signal to every axis mod jack connector, on mod jack pin #4. -
Page 9: Digital (Pulse And Direction) Interface For 6 Axis Motion Control
2. Digital (pulse and direction) interface for 6 axis motion control The IO6 breakout board provides differential and single ended step and direction both of which may be employed at the same time. a. Differential step and direction interface The first 6 jacks of the 8 jack module provide differential step and direction outputs for servo drives. -
Page 10: Spindle Control Overview
**************WARNING************** All Servo drive fault signals should be connected together so that a failure in one drive shuts down every servo drive at the same time. Failure to configure the servo drives in this manner can cause DEATH, INJURY or serious PROPERTY DAMAGE. Do not install drives that do not share the same fault line. -

either the appropriate M-code or the operator turns on the spindle with the “button” on the control screen. The hardware control sequence is as follows: The Mach3 control turns on either a CW or CCW relay. Then the IO6 sends an appropriate 0-10 volt analog signal out to the Variable Frequency Drive (VFD) which controls the spindle motor speed. -
Page 12: I06 Inputs For Measuring Spindle Rpm
MachMotion’s R2210 converter and then interfaced to the IO6 through a shielded CAT5 cable and Mod Jack #7 mentioned in the previous paragraph. The inputs to this mod jack are expected to be based on 5v differential signals, as are provided by a 26C31 Differential driver. -
Page 13: Opto-Isolated Digital Inputs Terminals
Phoenix Auxiliary terminal connections described in Parallel Port I/O Interface connections below. The speed measuring input is used in Lathe threading operations. The most reliable spindle speed sensing and position sensing is obtained by employing a differential incremental encoder mounted to the spindle. Alternatively, a 5V NPN optical sensor can be mounted on the spindle which would provide one pulse per spindle revolution. - Page 14 LED indicator below the corresponding input below the Primary terminal block. See page 17 figure 13 and 14. These seven inputs can be connected to a number of different types of devices and configured as described in the next section (10) entitled, OPTO-Input Connection Guide.
- Page 15 The example drawings have terminals with representative labels. The top row of terminals above the opto-isolated input terminals on the Primary Terminal Block has three terminals labeled GND and three terminals labeled +24 Volts. These labels correspond to the example drawings and are provided as voltage sources for the opto-isolated inputs.

and 15) can be configured as general purpose inputs through the phoenix terminals so labeled. For example, inputs 12, 13 and 15 can be used for spindle control as described under the section of this manual entitled Spindle control.
