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.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.The colors and styles of cables and CDs are random and cannot be specified, which will not affect their use.Colour:GreenMaterial:PlasticPackage Contents:1 x V3.25 5-axis control card1 x USB Cable1 x CDOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
