1. POWER SUPPLY AND CURRENT: This stepper motor operates on DC 10V–45V. It is recommended to use a switching power supply with DC 32V and a current rating up to 4.5A to support various applications. 2. AUTOMATIC HALF CURRENT FUNCTION: The driver board features an automatic half-current mode for energy efficiency and includes output short-circuit protection for reliable operation. 3. OPTICAL COUPLING AND HEAT DISSIPATION: The stepper motor controller uses a 6N137 high-speed optical coupler to ensure accurate performance at high speeds without losing steps. Equipped with an extended heat sink for effective heat dissipation. 4. EASY CONNECTION: The driver board uses a common anode input configuration with dual input terminals for simplified wiring and convenient installation. 5. NOTE FOR USE: Subdivision setting instructions are printed on the back of the control panel. Avoid reversing the power supply polarity to prevent damage to internal components. Do not set the current higher than the motor’s rated value.
