high-performance single-axis servo drive designed for precise motion control of brushless three-phase permanent magnet motors. Belonging to the
SCE900 series, it combines advanced digital control algorithms with rugged industrial design to deliver reliable positioning, velocity, and torque control in demanding applications. The
-002-01 suffix denotes a
factory-configured variant with standard firmware and voltage settings
The SCE905AN-002-01 serves as a critical component in industrial automation systems, translating control commands into motor motion while ensuring accuracy and dynamic response. Key functionalities include:
Digital Control Architecture:
- DSP-based platform with current loops and digital auto-tuning for simplified setup and predictable performance
- 24-bit resolver-to-digital converter (RDC) provides high-resolution position feedback (±0.005% accuracy)
- Sinusoidal current control minimizes torque ripple and ensures smooth operation across all speed ranges .
Modular Configuration:
- Removable option cards enable flexible expansion of I/O, communication protocols (e.g., Modbus RTU), or encoder interfaces .
- EEPROM memory stores system parameters (up to 1,000,000 write cycles), with optional card removal to prevent unauthorized modifications .
Power & Compatibility:
- Wide input voltage range: 90–264 VAC (single-phase) supports global power standards .
- High-current output: 15.9 A continuous / 31.8 A peak (convection-cooled) for driving medium-power motors .
- Compatibility: Works seamlessly with Pacific Scientific’s brushless motors (e.g., PSM series) and third-party actuators
