EA233 series servo drive is a high-performance small and medium power AC servo unit developed by Sine Electric. This series of products adopts advanced motor control dedicated DSP chips, large-scale programmable gate arrays (CPLD/FPGA) and PIM power modules, and has the characteristics of high integration, small size, perfect protection and high reliability. The optimized PID control algorithm realizes accurate full digital control of torque, position and speed with high precision and fast response. It provides advanced functions such as rigidity selection, real-time automatic gain adjustment, and automatic resonance suppression. It has a rich digital and analog interface and supports MODBUS communication protocol for easy networking. The two sub-series support motors using 2500-line incremental pulse encoders or 17-bit incremental magnetic encoders, Tamagawa's 17-bit incremental photoelectric encoders, and 23-bit absolute photoelectric encoders to meet different requirements for cost and performance. It can be widely used in automation fields such as CNC machine tools, printing and packaging machinery, textile machinery, robots, and automated production lines.

EA233 series servo drives also have models supporting EtherCAT bus (EA233E) to choose from.
