Performance Parameters

Mechanical Dimensions and Features

The document provides detailed mechanical dimensions in millimeters for various shaft types:

• Solid Shaft: 5 mm diameter with flattening
• Hollow Shafts: 8 mm and 14 mm diameters with torque support
• Shaft Tolerances: H7 tolerance class
• Maximum Axial and Radial Loads: Axial 15 N (20 N with housing), Radial 40 N
• Sealing Plates: 1.5 mm thick for hollow shaft variants

Bus Communication Interfaces

The PSD series supports multiple industrial communication protocols for integration:

• CANopen
• IO-Link (with E-Ident function)
• EtherNet/IP
• EtherCAT
• PROFINET

Order Code Structure

The order key is structured with multiple fields to specify the exact configuration:

• A: Type (e.g., PSD)
• B: Torque and output shaft type (e.g., 0.25 Nm with 5 mm solid shaft, 1 Nm with 8/14 mm hollow shaft)
• C: Rotation shaft orientation and housing position (horizontal, vertical, angles 0°, 90°, 180°, 270°)
• D: Bus communication protocol (CANopen, IO-Link, PROFINET, EtherCAT, EtherNet/IP)
• E: Electrical connections (standard or IO-Link specific)
• F: Protection class (IP 50 or IP 65)
• G: Software modules (standard, modulo function, parameter set changeover, target speed in process data)
• H: Certifications (CE/UKCA standard, NRTL optional)

Key Recommendations and Notes

• Positioning accuracy depends on torque rating; higher torque models offer better precision.
• IP 65 protection is achieved only when installed; motor shaft remains IP 50.
• IO-Link devices include additional software functions such as modulo and parameter set switching.
• Mechanical limits do not restrict the positioning range, allowing extensive rotation capability.
• Shock and vibration resistance ensure suitability for industrial environments.

Summary

The PSD 48x / 49x direct drives are compact, precise, and versatile motors suitable for industrial automation requiring accurate positioning and robust communication options. Their modular order code allows customization of torque, shaft type, communication interface, and protection level to fit diverse application needs.
