S403A-CA

The Danaher Motion SERVOSTAR S403A-CA is a compact digital servo amplifier engineered for precise multi-axis positioning, speed control, and torque regulation in high-demand automated machinery. Originally developed under the robust Kollmorgen/Danaher Motion platform, this drive provides high-performance motor commutation for brushless AC servo motors across assembly, material handling, packaging, and robotics applications.

Rated for a continuous output current of 3 A rms and peak current capacity up to 9 A, the S403A-CA delivers dynamic acceleration and smooth low-speed performance. It features an integrated CANopen interface for distributed fieldbus architectures, allowing streamlined commissioning, diagnostics, and parameter handling. Standard onboard monitoring circuitry defends against phase faults, overvoltage, short circuits, and thermal overload to protect both the amplifier and connected motor.S403A-CA
