Signal Amplification: Takes low-level control signals and boosts them to the high power levels needed to drive the motor effectively.
Power Conversion: Typically converts incoming AC line voltage (single-phase or three-phase) into the precisely controlled DC voltage (or synthesized AC waveforms) required by specific servo motors (DC brushed, DC brushless, AC synchronous).
Closed-Loop Control: Continuously compares the commanded motion profile (position, velocity, torque) with the actual motor state reported by the feedback device. This is the foundation of servo precision.
Error Correction: Uses advanced control algorithms (like PID - Proportional, Integral, Derivative) to calculate and output the exact power needed to minimize any tracking error and achieve the desired motion performance.
Communication & Configuration: Interfaces with the higher-level controller via protocols like CANopen, EtherCAT, Ethernet/IP, Modbus TCP, RS-485, Pulse & Direction, or Analog signals. Allows parameter tuning for performance optimization and diagnostics.
Protection & Monitoring: Safeguards the motor and drive system by monitoring critical factors (overcurrent, overvoltage, undervoltage, overheating, feedback loss) and triggering faults/shutdowns when necessary.
Regenerative Braking Handling: Manages the energy generated by the motor when decelerating or holding a load against gravity, either dissipating it as heat through braking resistors or feeding it back to the power source (regeneration).
