SD digital stepper driver series

CATALOGUE OVERVIEW

About this component series

The SYNTRON SD family provides digital control for compatible stepper motors using a DSP-based architecture and microstepping. The model table separates supply voltage, phase count, maximum current and supported motor sizes.

For example, SD-20403 uses a 12–40 V DC supply with up to 2.6 A peak output. Select the exact driver by motor winding current and required pulse interface; the supply rating is not a motor output-power rating. Ask for wiring diagrams and alarm behaviour for your machine controller.

Selection priorities for Motor parts & accessories

Part names do not establish interchangeability. Provide a drawing, model reference and the relevant operating conditions.

• Motor model and drawing
• Critical dimensions
• Material and finish
• Electrical or mechanical rating
• Quantity and compatibility

Use the SD reference when requesting a datasheet from SYN-TRON. Confirm these requirements against the exact offered model before comparing quotations.

Send a specification the manufacturer can quote

1. Application and load: describe the machine, required torque or power, speed and operating cycle.
2. Electrical supply: provide voltage, frequency, phase and any inverter or controller.
3. Installation: share mounting, shaft dimensions, frame constraints and operating environment.
4. Commercial requirements: state quantity, destination, target date and required certificates or drawings.
