Images are for illustration purposes only. E&OE Overview The MA860H is a high performance microstepping drive based on pure-sinusoidal current control technology. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drives on the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors Features Extremely cost-effective Good high speed performance Supply voltage up to 80VAC or +110VDC Output current up to 7.2A Self-adjustment technology Pure-sinusoidal current control technology Pulse input frequency up to 300 KHz TTL compatible and optically isolated input Automatic idle-current reduction 16 selectable resolutions in decimal and binary, up to 51,200 steps/rev Suitable for 2-phase and 4-phase motors Support PUL/DIR and CW/CCW modes Short-voltage, over-voltage, over-current and short-cicuit protection Specifications MA860H microstepping drive Input voltage : Up to +80VAC or +110VDC Output current : Up to 7.2A Pulse input frequency : up to 300 KHz Automatic idle-current reduction Over-voltage, over-current protection Suitable for : 2-phase and 4-phase motors Support : PUL/DIR and CW/CCW modes Operating Temperature : 70 C Power and Motor Terminal Assignments Terminal No. Terminal Name Description Terminal 1 +Vdc Power supply, 20~30 VDC, Including voltage fluctuation and EMF voltage.
