• Winding Configuration: Optimized for low inductance (4.9 mH) and high overload capacity (36.3 A peak current).
• Shaft Design: Plain shaft with shaft sealing ring for compatibility with gearboxes or direct-drive systems.
• Connector System:
  • Power: INS0481 connector for secure high-current transmission.
  • Encoder: Angular or straight cables (e.g., IKS4042/002.5) for flexible feedback integration.
• Mounting: Flange-mounted per DIN 42948, with M6 screws tightened to 10 Nm torque.

5. Installation & Commissioning

Step 1: Mounting

• Align the motor flange with the drive system using a 4-point M6 screw pattern.
• Tighten screws to 10 Nm ±10% using a torque wrench.

Step 2: Electrical Connections

• Connect the power cable (e.g., IKG4055/005.0) to the INS0481 terminal.
• Attach the encoder cable to the Hiperface DSL port, ensuring IP65 sealing.

Step 3: Parameterization

• Configure the drive controller (e.g., HDS02) with motor-specific parameters:
  • Rated voltage: 163 V
  • Pole pairs: 3
  • Torque constant: 0.74 Nm/A (RMS)

6. Maintenance & Service

• Cooling System: Clean cooling ribs monthly with compressed air to prevent thermal derating.
• Bearing Service: Replace bearings every 30,000 hours (L10h) or if abnormal noise occurs.
• Connection Audit: Inspect cables biannually for wear, particularly in high-flex applications.
• Brake Testing: Verify holding brake functionality quarterly using the controller’s diagnostic interface.
