EA350 High-Speed Closed-Loop Servo Drive Controll | RFQ Sourcing Details

The EA350 is a closed-loop servo drive controller intended for robotics and industrial automation systems. It supports SVPWM and vector control, with six operating modes: speed, position, torque, speed/position, torque/speed, and position/torque control. The front panel provides five keys and a five-digit LED display.

Available power configurations include single-phase 220–240 V at 0.1–1 kW, three-phase 220–240 V at 0.75–1.5 kW, and three-phase 340–460 V at 1.5–30 kW.

Cooling is Stated operating limits include a 0–40°C working temperature, up to 90% RH without condensation, altitude up to 1,000 m, and vibration up to 4.9 m/s² at 10–60 Hz, excluding operation at resonance.

For position control, the controller accepts differential pulse inputs up to 500 Kpps or open-collector inputs up to 200 Kpps. Supported pulse formats include pulse plus sign, A/B-phase orthogonal pulse, and CW/CCW.

Position commands can be Low-pass, FIR, and trapezoidal smoothing options are listed, together with ±1 command-pulse position accuracy. Speed commands may be provided through an external analog input, digital speed settings, multistage speed settings, or inching commands.

The analog command range is -10 to +10 V, with 10 kΩ input impedance and a 200 µs time constant. With a 23-bit encoder, the listed speed regulation ratio is 1:5000 and bandwidth is 3,000 Hz.

Torque control supports external analog or digital torque commands, a -10 to +10 V analog input, and digital or external analog speed limiting. Listed torque-control current repetition accuracy is ±1%. Modbus RTU communication is supported.

Feedback options listed are an RS485 serial communication encoder, RA-CODER, or FA-FORMAT protocol, including a supported non-standard FA-FORMAT version. Encoder outputs include differential A/B/Z signals and open-collector pulse outputs.

The controller also provides configurable digital inputs and outputs for functions such as drive disable, inching, servo-ready indication, brake output, zero-speed indication, limit states, warnings, and alarms.

Protective functions include listed responses for over-voltage, under-voltage, over-speed, overheat, overload, encoder alarms, excessive position error, and EEPROM faults. The alarm-tracking function records four groups of historical alarms and related data.

A regenerative brake unit is built in;only some specifications include a built-in brake resistor, while an external resistor can be connected.

Before procurement, confirm the exact voltage and power variant, compatible motor and encoder protocol, required feedback and I/O configuration, brake-resistor arrangement, and whether any optional hardware is needed.

Buyers should also verify the certification scope, dimensional drawing, connector and cable package, tuning requirements, environmental derating, warranty, lead time, and final customization details for the selected configuration.
