RE: [CAD_CAM_EDM_DRO] Which controller card for EMC?

Jim,

The Vital board is preferred as it is pci and has more dio.
I have been using the stg2 for several years however.

Emc in servo mode can be used to drive a simple torque, velocity,
or voltage mode servo amplifier with an analog voltage.

Emc does not support dual loop encoding. The cards do not
have sufficient encoder inputs anyway.

But that could be changed...

Subject: [CAD_CAM_EDM_DRO] Which controller card for EMC?


I am in the stages of a 5-axis mill and I'm to the point of picking a
controller for EMC.

Here's the specs:
- X,Y,Z,A, and C axes
- Parker Compumotor SM232B servos on all five axes
- Parker Compumotor TQ10 servo drivers for all servos
- NC generated by Pro/NC
- Class 3 or better ballscrews on X,Y, and Z
- Dual worm anti-backlash drive on A and C

As I am using more than four axes, I have narrowed my choices down to two
cards so far:

- Vital Sytems MOTENC
- Servo2Go Model 2 card

I would eventually like to add linear encoders (possibly absolute) on the
X,Y, and Z and
additional rotary encoders on the A and C coupled directly to the driven
axis.

Does anyone know if dual loop encoding (encoder fusion) has been used with
EMC thus
far?

What recommendation do any of you have for the cards? Other thoughts?

Jim
