The 241 is a miniature stepper motor controller with a RS-232 interface that can be commanded using ASCII coded instructions. Instructions are simple, intuitive and fault-tolerating. User is not required to have advanced knowledge on stepper motor driving.

RS-232; 4A; 2 Sensor

Motor Driving Characteristics

  • Wide supply voltage range 12 ~ 40VDC
  • Output current 4A, instruction adjustable
  • Full to 1/16th micro-step resolution
  • Dual full H-bridge with PWM constant current control


RS232 Interface

  • RS232 three-wire serial communication

Embedded DSP Microprocessor

  • Based on a 64bit DSP
  • Quadrature encoder based closed-loop control
  • Linear and non-linear acceleration and deceleration, S-curve, PT/PVT displacement control
  • Power-failure position protection
  • 2 sensor input ports, 1 analog input (12Bits)
  • 8 programmable real-time event-based change notifications
  • 9 programmable actions triggered by 6 sensor events

The 241’s architecture includes a communication system, a basic motion control system, an optional Quadrature encoder interface and a real-time event-based change notification system.

The embedded 64-bit DSP controller guarantees the real-time processing of the motion control and change notifications. The entire control operates within 1 millisecond.

242 controllers can be mounted onto NEMA17/23/34/42 series stepper motor through adapting flanges. Total thickness of the controller is less than 16.5mm. Enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation.
