Vertical panel mounting style is adopted.Overall dimension is 140mm by 270mm by 50mm. Approximate unit weight is 3.9 kilogram.Heat dissipation relies on natural convection and internal heat sink.Operating ambient temperature is from 0 degree Celsius to 55 degree Celsius. Storage temperature ranges from minus 20 degree Celsius to 70 degree Celsius.Working humidity keeps between 5 percent and 90 percent without condensation.

COP10A and COP10B serve as FSSB optical fiber connection ports connecting with CNC system.CX30 port is used for motor encoder signal connection.CXA19A and CXA19B are terminals for 24V DC power and control signals.CZ7 is main three phase power input terminal.JX5 is power output terminal connecting servo motor U, V, W and PE lines.CX29 is emergency stop signal interface.

Applicable to all FANUC Beta i series 400V grade AC servo motors.

High voltage working design reduces operating current and wiring specification.Optical fiber communication effectively resists electromagnetic interference and ensures stable signal transmission.High response vector control realizes quick response and smooth running performance.Modular compact structure facilitates installation and daily maintenance.Status indicator lamps support rapid fault inspection and diagnosis.

Mount the amplifier vertically and reserve sufficient ventilation space around the device.Cut off all power supply before wiring work. Follow correct phase sequence during power connection.Apply shielded cables for motor and encoder wiring. Separate power lines and signal lines to avoid interference.Fasten all wiring terminals with proper torque and complete reliable grounding connection.

High voltage remains inside the device after power off, do not touch internal components casually.Use wires meeting 600V voltage insulation standard.Stop operation immediately once abnormal heating, noise or alarm occurs.Replace damaged cables and connectors in time to guarantee operational safety.
