- IP67-rated sealed connectors for dust and water resistance
- Reinforced bearing design to handle high radial loads
Working Principle:
The motor operates as a three-phase AC synchronous servo. The drive supplies precisely controlled current to the stator windings, creating a rotating magnetic field that interacts with the permanent magnet rotor. The integrated encoder continuously feeds position data back to the drive, enabling closed-loop control of position, speed, and torque. The holding brake is spring-applied and electrically released — when the drive is enabled, the brake disengages to allow free rotation; when power is lost, the spring mechanism clamps the brake disc to hold the shaft stationary.
Installation Requirements:
- Mount on a rigid, flat surface using the standard flange interface to ensure proper alignment
- Connect the single cable system securely, ensuring proper shielding for EMC compliance
- Wire the brake control circuit to the designated drive outputs with correct voltage
- Ensure adequate ventilation around the motor housing for thermal management
- Verify the drive is configured for the P1/S1 encoder type
Usage Notes:
- The holding brake (B1) is designed for static load retention only — do not use it for dynamic braking or deceleration
- Verify the brake release voltage matches the drive output specification before commissioning
- Monitor motor temperature during continuous heavy-load operation
- Check brake gap and wear periodically if the brake is engaged frequently
- Do not exceed the permissible radial and axial shaft loads specified in the technical manual
- Handle with care to avoid electrostatic discharge damage to the encoder electronics
