PDC1 series miniature stepper motor controllers with RS232 interface can be mounted onto NEMA17/23/24/34/42 series stepper motor through adapting flanges. Embedded 64-bit calculating precision DSP controller guarantees the real-time processing of the motion control and change notifications. Entire control process is finished within 1 millisecond. User device can command these controllers through RS232 protocol using ASCII coded instructions. Instructions are simple, intuitive and fault-tolerating.

PDC1 series controllers can realize open-loop and encoder-based closed-loop control. The architecture includes communication system, basic motion control system, absolute position counter, quadrature encoder interface and real-time event-based change notification system. Furthermore, three optional modules are available: Advanced Motion Control Module (linear/non-linear acceleration/deceleration, S-curve PT/PVT displacement control), Encoder-based Closed-loop Control Module and Sensor Input Control Module.
