L1, L2, L3: Main Power Input Terminals
L1C, L2C: Control Power Input Terminals
U, V, W: Motor Power Output Terminals
CN1 / CN2: RJ45 Ports for Communication (e.g., RS485 or PC connection for configuration)
CN3 (Large Port): I/O Port for receiving Pulse/Direction signals from a Controller or PLC.
CN4 (Bottom Port): Encoder Port for receiving feedback signals from the motor, enabling precise position control.

Key Features

Features a digital display on top for monitoring status and setting parameters.
Includes a prominent “CHARGE” indicator light to signal residual voltage in the capacitors (exercise caution when disconnecting power if this light is active).
A popular model for small to medium-sized CNC machines, known for its ease of installation and configuration.
