Stepper Motor Driver – PoStep60-256

Product Description

The PoStep60-256 stepper motor driver incorporates advanced stepper motor controller and external N-channel MOSFETs. Because of great flexibility, it can drive a bipolar stepper motor or two brushed DC motors. An integrated micro-stepping indexer is capable of step modes from full step to 1/256 step. Adaptive blanking time and various current decay modes, including an auto-mixed decay mode, are available in the settings. Thus ultra-smooth motion profile can be achieved.

A standard step/direction or PWM interfaces allow for easy interfacing to controller circuits. All running parameters (output current (torque), micro stepping, step mode, decay mode…) can be set over USB. Furthermore, storing of all parameters for standalone operation is possible to onboard non-volatile memory. It features over current protection, short circuit protection, under voltage lockout and over temperature internal shutdown to protect the stepper motor driver and the motor. These fault modes are indicated using the fault LED, while additional information is available in configuration software for detailed fault analysis.
