Feature: 1. STABLE PERFORMANCE: The driver adopts 32 bit ARM chip with built in smoothing filtering function, so the external input can operate normally even without acceleration and deceleration. 2. COST SAVING: The drive has a built in microcontroller and point action mode, which can replace the PLC on most occasion and significantly reduce user costs. 3. SAFE USE: The driver is protected by over current, over voltage, over speed, over heat and tracking error, etc., which is safe to use. 4. SETTABLE CURRENT: The drive uses advanced vector current, speed and position closed loop control algorithms, and the current can be set at will. 5. HIGH RESPONSE FREQUENCY: The driver is an optocoupler isolated differential signal input, and the pulse response frequency can be up to 200KHZ, which can be set at any subdivision. Specification: Item Type: Stepper Motor Driver Material: Aluminum alloy Cooling Method: Natural cooling or additional radiator Use Environment: Use Occasion: Try to avoid dust, oil mist and corrosive gas Temperature: 0℃-50℃ Humidity: 40-90%RH Vibration: 10-55Hz/0.15mm Storage Temperature: -20℃-+65℃ Weight. Approx 300g / 10.6oz Parameter Minimum value Typical Value Maximum Value Unit Continuous output current 1 5.6 A Input supply voltage 18 24 80VDC VAC Logic input current 7 10 20 mA Total power 120 W Pulse frequency 0 200 kHz Insulation resistance 500 MΩ Digital output port logic current 100 mA Digital output port withstand voltage 24 V . Package List: 1 x Stepper Motor Driver Note: AC input voltage in AC18V‑80V, DC input DC24V‑110V can work normally, power supply power is not higher than 200W, the higher the voltage input, the greater the current setting motor torsion, high speed performance, but the motor heat more, in principle, as long as to meet the use, the smaller the current setting the better.
