  • Easy to Use:
    • Setup through a simple PC program
    • Operate the motor through PC program or use stand-alone
  • Speed control: High-resolution for accuracy and precision with or without load (.02%-.08% depending on motor speed and number of poles)
  • Low Jitter: Typically <1uS
  • Motor speed: Maximum 30K RPM
  • Programmable motor power supply
    • 0-24V, 0-4A output
    • Better than +/-1% Voltage Output Adjustment Accuracy
  • Over-current and lock rotor protection: Virtually eliminates motor or driver damage
  • Unique design:
    • All-digital design. No pots to adjust.
    • Unidirectional motor quick start: No reverse motor rotation
    • Constant current ramp for short start time and motor protection
    • 200 kHz PWM current regulator for better speed control and efficiency
  • Communication with driver through RS232 port allows:
    • Motor Configuration for Speed; Motor poles; Max drive current; Over-current limit: start and run; Time limit expired: start, ramp, lock
    • Motor Control Commands for Run; Coast; Brake; Stop; Clear errors; Reset
    • Data Query for Run current; Speed; State: off, starting, ramping locking, locked, active brake, coasting, braking; Over-current limit error: start, run; Time limit expired error: start, ramp, lock
  • Easy integration into your test environment:
    • Communicate through a standard RS232 (USB adaptor available)
    • LabVIEW Library and example code
    • Windows DLL
  • Digital I/O motor control:
    • Input for controlling run/stop
    • Output to indicate speed lock/error
  • Instrumentation interface signals:
    • Current sense resistor: direct differential connection
    • Run-current voltage: amplified to 1Amp/Volt Scale with analog ground
    • Once-per-rev index digital output
