PDC2 series miniature stepper motor controllers with CAN network interface can be mounted onto NEMA17/23/24/34/42 series stepper motor through adapting flanges. Total thickness of the controller is less than 16.5mm.

With PDC2 series controller, it is simple to construct a control system. Users can control the whole “motor-sensor-third party actuator” system through their own CAN based host by using “SimpleCAN” protocol. Users also can control the system through a gateway provided by PrimoPal, by using RS232 based string or “SimpleCAN” protocol. One gateway can network with up to 100 pieces PDC2 controllers. PDC2 series controllers can realize open-loop and encoder-based closed-loop control. Its architecture includes communication system, basic motion control system, advanced motion control module (linear/non-linear acceleration/deceleration, S-curve PT/PVT displacement control), sensor input control module, TTL output control module and user programming module.

Embedded 64-bit calculating precision DSP controller guarantees the entire control process finish within 1 millisecond. Instructions are simple and intuitive. PrimoPal provides free Microsoft Windows based VB/VC demo software and corresponding source code. Enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation.
