Performance Parameters

Mechanical Dimensions and Features

The document provides detailed mechanical dimensions in millimeters for various shaft types (solid and hollow) and torque supports. Key dimensions include shaft diameters (5 mm solid, 8 mm and 14 mm hollow), tolerances (H7), and sealing plate thickness (1.5 mm). The hollow shafts are available with torque supports and sealing plates to ensure mechanical stability.

Bus Communication and Connectivity

• Supported protocols: CANopen, IO-Link, EtherNet/IP, EtherCAT, PROFINET
• Electrical connections: Standard 3 plugs/sockets; IO-Link devices use 1 plug
• Mounting: 4 x M3 screws with 4.5 mm depth

Ordering Information

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

• A: Type (e.g., PSD)
• B: Torque and output shaft (e.g., 0.25 Nm with 5 mm solid shaft or 8/14 mm hollow shaft)
• C: Rotation shaft / housing orientation (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)
• 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

• IP 65 protection is achieved when installed; motor shaft remains IP 50.
• Positioning accuracy depends on torque rating; higher torque models offer better precision.
• Mechanical limits do not restrict the positioning range, allowing extensive rotation capability.
• Shock and vibration resistance comply with international standards ensuring reliability in industrial environments.
• Torque supports and sealing plates are critical for hollow shaft configurations to maintain mechanical integrity.

Summary

The PSD 48x / 49x direct drives are versatile, high-precision motors suitable for industrial automation requiring accurate positioning and robust mechanical design. They offer multiple shaft options, communication protocols, and protection classes to fit diverse application needs. The detailed ordering key facilitates customization, while compliance with IEC/DIN standards ensures durability and reliability.
