SMD-4.2DIN Stepper motor driver SMD-4.2DIN SMD-4.2DIN is a new-generation stepmotor driver with high dynamic performance. It is designed by our engineers for medium size stepper motors, output current is under 4.2A per motor's phase. The driver provides pulse (STEP/DIR) position control, shaft angle regulation according to an analog signal and analog speed control operation modes. The driver is equipped with an internal brake resistor. External brake resistor can be connected as well if needed. The main parameters: • Max. current per phase: 0.42 - 4.2 Amp • Power supply: 24 - 48 VDC • Microstepping mode: 1, 1/2, 1/4,1/8, 1/16, 1/32, 1/64, 1/128 The controller provides 3 different control modes: • STEP/DIR pulse position control; • Analog speed control; • Analog position control. The controller provides two phases commutation modes - current and voltage: The voltage mode provides smooth motion at low speeds and accurate microstepping division. Another special feature of the voltage control mode - the controller can detect if the rotor is locked. The current mode provides better torque and higher speed.
