DELTA ASDA-A2 DRIVES

[Median9]

Are the subject drives from Delta (http://www.delta.com.tw) compatible with any of the motion controller cards from NI? 4 Axis Acceleration, Velocity and Position control is desired.

What kind of drive or motor are you interested in using?  Our controllers use common signal standards, and are compatible with most drives.  For example, most stepper motor drivers use 2 lines for Step and Direction, and our cards support this interface.  If you could direct me to a specific drive or line of drives, it would be possible to offer more specific advice.

Thanks for your response. I am checking the links however, we have sized the motors already. One of the following can be considered depending on NI's compatibility with these drives:

DRIVES:

1-    ASDA-A2-04-21-L (Full-close Control)

2-    ASDA-A2-04-21-M (CANopen)

3-    ASDA-A2-04-21-F (DMCNET)

4-    ASDA-A2-04-21-U (Internal Position Control)

5-    http://www.delta.com.tw/product/em/motion/motion_servo/download/manual/DELTA_ASDA-A2_M_EN_20120913.p...

PAIRED MOTOR:

1-    ECMA-C10604ES

We are looking for optimal close loop control (4 Axis).

Median9,

You should be able to utilize either a 7344 or a 7354 with the drives as listed.  However, when doing this, you will need to ensure that they are set to torque mode, which is how our controllers best work with drives.  In that mode, the analog input range is (±)10V, which is exactly the same as our controllers' output range.  You could most likely use the speed control as well, but I would suggest torque control for use with our controllers.  This may take a bit of wiring to actually set up, but is completely possible.  For more information on what this may look like, feel free to check out page 3 on the following link (except replace the AKD with the Delta drive you are looking to use):

However, if you are only looking for position, velocity, and acceleration control, you may not need to use a controller at all.  The drives listed have the ability to internally control both speed and position, as is outlined on page 6-1 of the manual attached.  If you think you could configure the drive to output a set of commands in these modes, it would keep you from having to use a controller and would most likely save you a bit of money.
