![Industrial 3-Phase Open-Loop Stepper Driver [3S8A]](/static/upload/image/20230915/1694760801889554.webp)
Brand-new 32-bit DSP technology
Backlash compensation and circular-interpolation compensation for laser cutting and engraving machines
Supply voltage DC 24–80 VDC (24/36/48 V recommended), withstands up to 110 V, reverse-polarity protected
Ultra-low vibration and noise
Built-in high microstepping for smooth low-speed operation
Automatically matches motor parameters at power-on
Variable-current control greatly reduces motor heating
Standstill current automatically halved, reducing motor heating
Drives 3/6-lead three-phase 42/57/60/86 three-phase open-loop stepper motor
Pulse, direction, enable (free) signals and alarm output are optically isolated
Maximum pulse frequency up to 1000 kHz (factory default 350 kHz)
Supply voltage DC 20–80 V (24/36/48/60 VDC recommended); protected against reverse polarity and miswiring.
Current is easy to set, selectable from 1.5–9.0 A, also settable via serial port
Microstep range 200–51200, higher values customizable, any value settable via serial port
Over-voltage, under-voltage and over-current protection
IO pulse generation, dual pulse, single pulse and self-test
Serial port configuration
