Driving 140V Baldor Servo with PMDX-126
« on: September 03, 2019, 03:09:58 PM »
Any and all...

I am thinking of using Advanced Motion Control (AMC) 30A20AC PWM servo drivers with the PMDX-126 for full power on this incomplete control retrofit:

OEM CNC mill factory retrofit (Eagle) where other owner stalled on PMDX-126 RevC for repair / replace of original Anilam controller.

Problem (?) I am trying to solve:

Three Gecko 320X drivers in place now have 80V out put max. Baldor (Anilam Elec.) servos rated for 140V, 5.9Amp continuous, 30 Amp max.

It seems to me that the Geckos on this machine are under rated for above Baldor servos.

PDMX-126 has Smooth Stepper and PDMX-107 Spreed Control on board as well.

Is this proposed configuration, AMC 30A20AC PWM servo drivers (or similar AMC driver) with the PMDX-126 possible? Compatibility?

Any and all help / guidance / suggestions / other resources would be appreciated!

The PMDX-126 can work with any motor driver that has step/dir input signals.  If the AMC servo drivers have a step/direction interface (like the G320X drivers), then you should be able to use them in the same manner as the G320X.
