As shown in the diagram, we recommend selecting stepper motor drivers based on motor size and current rating. For current specifications, should you match the stepper motor driver's PEAK or RMS value?
Based on our engineering experience:
- Standard Operation: Match the stepper motor driver's RMS current to the motor's rated current for optimal performance
- Overheating Conditions: Switch to matching the stepper motor driver's PEAK current with the motor rating
- Duty Cycle Guidance:
- Short-term operation: Use RMS values
- Continuous operation: Use PEAK values
For detailed configuration instructions, please refer to: How to Set the Current on Stepper Driver, RMS or Peak?
