Brief Product Description

FEC AFC1500 SAN4-40M is an AC servo axis controller belonging to the AFC1500 multi-axis precision bolt tightening system. Designed for industrial assembly torque control, it drives the servo tightening spindle to realize closed-loop control of torque, angle and rotation speed. Powered by 3-phase AC200~220V input, this unit features high-speed response and multi-loop control algorithms to guarantee consistent bolt fastening quality. It supports production data logging and fault waveform recording for quality traceability, and communicates with host controllers, PLC and HMI for line integration. With industrial anti-vibration and EMI suppression design, it runs stably 24/7 on automated assembly lines. Fully tested surplus and refurbished FEC AFC1500 SAN4-40M controllers are available for legacy tightening system maintenance, servo axis controller replacement and assembly line retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Tightening torque instability or servo alarm after installing SAN4-40M?
  A: Check encoder wiring and motor cable integrity, verify parameter recipe settings, inspect 3-phase power supply balance, and eliminate grounding and electromagnetic interference.
• Q: Does FEC AFC1500 SAN4-40M support hot-swap replacement?
  A: Hot swap is not allowed. Lock out the machine, cut off the controller and motor power, perform lockout-tagout before replacement to prevent accidental spindle rotation and safety hazards.
• Q: What system is SAN4-40M used for?
  A: It is a servo axis controller for FEC AFC1500 multi-axis precision bolt tightening control system.
• Q: What power supply does SAN4-40M require?
  A: It uses three-phase AC200~220V 50/60Hz industrial power supply.
• Q: Is FEC AFC1500 SAN4-40M available for new assembly projects?
  A: This legacy servo axis controller is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing tightening system maintenance and retrofits.
