Digital Signal Synthesizer
(clean Megahertz range pulse stream)
SwapAxis function
(switches the InTurn™ from Indexing to Turning)
Line Driver
(creates differential signals for Step and Dir)
PRE-WIRED CONNECTIONS:
InTurn™ controller to combo board
See the attached wiring diagram
Connect wires to Your Servo Drive:
Step+ and Step- differential pairs. Use twisted pair wire.
Dir and Direction - Shielded CAT6 wire recommended.
Note: some drives do not support differential pairs.
For those drives use only the
+
signals.
Leave the
–
terminals unconnected
Wire with both foil and braided shielding is recommended.
NOTE: Do NOT run power and signal wires in the same cable.
Example: the two twisted pairs that are used for the STEP and DIR should be in a separate shielded
cable. This is especially important with 24V industrial drive electronics.
NOTE: Operation of the high power 24V signals in the same cable as differential signals will induce a
spike in the STEP/DIR wires that will disable the Digital Signal Synthesizer on the
InTurn™
Controller’s interface combo board.
Connect wires to Your
Break Out Board
:
‘A’ Axis STEP
(color choice and Pin number choice by User)
Select any available OUTPUT pin on your BOB
Set MACH to output the A axis Step on this pin.
Wire from this BOB Pin TO the A Step pin on the Combo Board
‘A’ Axis DIRection
Connect in the same way as the Step Pin above
Connect wires to a 5 Volt DC power supply.
The InTurn™ motor controller draws more power than early USB ports can supply, so it must be fed
separately. The power supply wire in the
InTurn™ USB cable is severed to prevent an overdraw
which will shut
down your PC’s USB port(s).
