Technical Advantages & Materials
1. Intelligent Servo Controller Features
-
Real-time Display: Built-in digital display shows actual stroke percentage and fault codes for easy troubleshooting.
-
High-Precision Control: Features an imported high-speed CPU and hybrid circuit design. Electronic braking eliminates motor inertia, ensuring Zero Oscillation and high positioning accuracy.
-
High Frequency Operation: SCR (Silicon Controlled Rectifier) output allows for high-frequency switching (up to 1200 times/hour).
-
Robust Protection: The circuit board is fully resin-potted for vibration resistance, dust-proofing, and moisture isolation. Optoelectronic isolation ensures strong anti-interference against PLC/DCS systems.
2. Premium Hardware Components
-
Feedback System: Uses a Japanese Sakae conductive plastic potentiometer. Its unique spring-loaded mechanism eliminates gear backlash, providing continuous and stable real-time sampling.
-
Mechanical Strength: ADC12 aluminum housing with a 150°C heat-resistant powder coating. Output shafts made of heat-treated 40Cr steel with spline connections to prevent torsional failure.
-
Superior Sealing:IP68 Protection Class (Report No: C16040-WT) using German Oberst TC oil seals.
-
Lubrication: Lifetime Mobil synthetic grease ensures smooth transmission and wear resistance.
