Anyone ever try this? Since the PMDX-106 is a PWM type board can it drive the KBLC as a speed controller?
If so how did you set it up?
I'm using Mach3.
I've skimmed through the PMDX-106 Application Notes but not sure they will work together.
Thanks in advance,
Yes, the PMDX-106 can control a KBLC motor driver.
The PMDX-106 does the analog control by simulating
the speed pot normally connected to the KBLC. The
PWM signal will control the analog voltage and will
also turn on and off a small relay on the PMDX-106
for commanding Forward run. We do not recommend
using the Inhibit function on the KBLC or KBIC drivers
as a way to stop the motor because it is not failsafe
when wiring breaks. We recommend using the small
Forward relay on the PMDX-106 to control a larger
relay the removes the AC mains power from the KBLC
when the motor should stop. The basic KBLC cannot
reverse the motor, so no direction signal is needed.
The PMDX-106 has an on board inverter to provide
the isolated power needed to safely interface with
drivers like the KBLC whose interface signals ride
at AC mains voltage potential.
