The CRK series with built in controller couples a stepper motor with a compact, lightweight microstepping integrated controller driver.
  • Controller features RS-485 communications for easy programming and multi-drop capability.
  • The High Torque stepper motor features a Harmonic (HG) gear, highest permissible torque, high resolution, non-backlash (0 arc minutes) and smooth low-speed rotation.
  • Unit package includes - Motor, Driver, Motor lead wire and lead wire for driver connection to motor 24 in (600mm), Flat I/O connection cable 39.37 in (1m), Connector for power supply
  • USB to RS-485 converter not included. See Downloads for suggested converters.
