1. Comaptible with software. 2. Support XP, WIN7, WIN8, WIN10, support tablet computers, as well as 64-bit systems. 3. External wide voltage input, 12-24V, and anti-reverse connection function. 4. All input signals are isolated by optical coupling, which can be connected to emergency stop, tool setting, limit, return to zero, etc., to computer safety. 5. It provides 0-10V analog voltage output isolated by optocoupler, and can control the frequency converter input by 0-10V analog voltage to control the spindle speed.<br><br>Provide PWM output (5V level) isolated by optocoupler to control other PWM controlled spindle speed controllers. Provide 4 output ports (5V level), which can be connected to a relay module with optocoupler to control water cooling, , etc. It can be connected to a stepping motor driver with a common anode or common cathode input, a level of 5V, and an optocoupler input. At the same time, a 5-axis interface cable socket (HX2.54) is provided, which is convenient for connecting the stepper motor driver. Set inverter: 1. Set the inverter to external terminal start. 2. Set the frequency control mode of the inverter to analog (0-10V) input control. Caution! Please mind the power polarity and drivers direction. Please don't put the drivers or motors on/off when power on. Please disconnect all motors when adjust driver current.
