Description
The Rtelligent R42 is a digital stepper driver designed for 2-phase hybrid stepper motors, particularly suitable for motors with a flange size below 42mm (NEMA 17). It operates with a DC input voltage range of 18V to 48V and offers a peak current output of up to 2.2A. The driver utilizes a 32-bit DSP platform, implementing micro-stepping technology and a PID current control algorithm to enhance performance. This design results in reduced noise, vibration, and heat generation, while delivering high-speed and high-torque output.
Key Features
- Voltage Range: Operates with an input voltage range of 18V to 48V DC.
- Current Regulation: Adjustable peak current from 0.3A to 2.2A via convenient DIP switches.
- Micro-Stepping: Supports 16 micro-stepping resolutions for ultra-precise motion control.
- Advanced Control Algorithms: Features advanced PID current control algorithms for efficient power usage.
- Resonance Suppression: Minimizes mechanical noise and vibration with built-in resonance suppression.
- Thermal Efficiency: Compact physical size paired with effective heat dissipation channels.
- Robust Protections: Includes comprehensive overvoltage, undervoltage, overcurrent, and overtemperature protections.
- Signal Flexibility: Fully compatible with pulse/direction signals ranging from 3.3V to 24V.
Benefits
- Whisper-Quiet Operation: DSP-powered PID current control and resonance suppression drastically reduce motor noise and vibration.
- Reliable Thermal Stability: Efficient heat dissipation and wide current adjustability prevent overheating during prolonged operational runs.
- Easy Configuration: Onboard DIP switches allow quick, solder-free tuning of micro-stepping and current parameters.
