PSD2505C is a 2-phase CANOpen closed-loop stepper driver with DC input, using a dedicated 32-bit DSP motor control chip. It features 16 microstep settings, intelligent current adjustment to reduce vibration, noise, and heat, and ensures low torque attenuation with speeds up to 3000 rpm. The driver combines high-speed performance with rigidity, leveraging both servo and stepper advantages. It supports up to 32 devices via an isolated CAN bus and includes a built-in single-axis controller for speed, position, homing, and multi-segment position control. Connectivity includes 2 high-speed differential optically isolated inputs, 5 optically isolated inputs, and 3 optically isolated outputs. Voltage range: DC 24–50 V.
