Product Description

The STD-840-S8M-40 is a high-performance stepper motor controller designed for precision motion control, compatible with S8M-40 NEMA 34 stepper motors. Part of the STD Series Motor Controller family, it integrates 4 digital inputs and 2 analog outputs, supporting direct connection to up to 8 expansion modules. Equipped with RS-485, CAN, and Ethernet interfaces, it operates within a wide voltage range of 12-48V DC and functions reliably in temperatures from -20°C to 70°C. Ideal for industrial automation, CNC machinery, and robotics, it features a compact 2.4-inch display for real-time monitoring, a built-in 2000mAh backup battery, and a sensor detection range of up to 5cm. Its advantages include rapid response and seamless integration with STD-840 Stepper Motors, though thermal management may be required under continuous high-load operation.
