Hello everyone,
I’m working on a project where I need to control a Maxon DC motor (with US Digital encoder) using a Copley Controls AccelNet BPL-090-14 servo drive. I’m trying to figure out if it’s possible to send signals directly from LabVIEW through NI DAQ USB 6221 to the drive for motor control.
So far, here’s what I understand:
-
The AccelNet drive can be configured to accept different command sources (analog ±10V, step/direction, etc.).
-
LabVIEW can generate signals through the DAQ (analog outputs, digital signals).
-
The encoder feedback would go directly to the drive, not to the DAQ.
What I’m trying to clarify:
-
Can I control the motor position/speed/torque by outputting the appropriate control signals from LabVIEW → DAQ → AccelNet drive?
-
Do I need to use Copley’s CME software for setup first, then switch to LabVIEW for real-time control?
-
Is there a recommended way (or better NI hardware) to interface LabVIEW with the AccelNet, rather than using a DAQ card?
My main concern is whether LabVIEW + DAQ is a feasible path for real-time motor control, or if I should instead look into fieldbus communication (e.g., CANopen, EtherCAT) with the drive.
Any advice or shared experiences with a similar setup would be greatly appreciated!
