Title: PMDX-107 for SX3 with LMS PN 4645 spindle control upgrade PCB
Post by: Screener on May 03, 2016, 01:33:15 PM

Could anyone help me with some information or their experiences controlling the BLDC motor in the Grizzly G0619 (SX3) with a PMDX107 and the SX3 spindle control upgrade PCB.


Has anyone used the PMDX-107 under Mach3 to send signals to the upgrade SX3 spindle control PCB
the wiring specs of the spindle controller upgrade are here http://littlemachineshop.com/instructions/4213CNCSpindleControlUpgradeKit.pdf

thanks in advance

Looks like a straight forward match to the PMDX-107:

PMDX-107       SX3
AGND             GND
AOUT              AVI
AREF               No connection
COM               GND
Fwd/Run         START/STOP
Rev/Dir          F/R

And you need to set the DIP switches on the PMDX-107.  I am presuming you have the PMDX-107 installed on a PMDX-126 and that your ARE using the charge pump signal on pin 17 (which we highly recommend).  Let me know if you are not using a charge pump signal.  See the PMDX-107's User's Manual section 4.1 to 4.5 for these DIP switch settings.

CONFIG1, CONFIG2:  both "off" (normal mode)
CONFIG3: "On" (relay contacts act as "run" and "direction")
CONFIG4: "Off" (require "charge pump OK")
SLOW: either setting, start with "Off" for fast filter response.
5V/10V: "Off" (0 to 10V analog output - SEE NOTE BELOW!!!)

NOTE: you may need to adjust pot W1 on the SX3 board when the PMDX-107 is outputting 10V to set the max RPM on your spindle.

For the Mach3 configuration see our app note AN001 (http://www.pmdx.com/AppNotes).
