Product Description
The ELAU C400/10/1/1/1/00 VCA07AAAA0AA00 is a high-performance servo drive designed for precision motion control in industrial automation, particularly in high-speed and high-accuracy applications such as packaging machinery, printing presses, and robotic systems. As part of Schneider Electric’s ELAU range (now integrated into the Lexium Motion portfolio), this drive combines robust power delivery with advanced control algorithms, making it ideal for driving servo motors in complex multi-axis systems where synchronization and dynamic response are critical.
The model designation “C400/10/1/1/1/00 VCA07AAAA0AA00” breaks down its key specifications: “C400” indicates the base model with a 400V AC power rating, “10” denotes a 10A current capacity, and the subsequent codes define communication options, feedback compatibility, and hardware variants. The “VCA07AAAA0AA00” suffix specifies the motor interface and cooling configuration, optimized for seamless integration with ELAU’s servo motor ranges. This drive supports advanced control modes such as vector control and servo regulation, enabling precise torque, velocity, and position control—essential for applications like label alignment, die cutting, and robotic pick-and-place operations. Its compact design and modular architecture allow easy integration into existing control cabinets, while built-in safety features ensure reliable operation in industrial environments.

Usage Methods
- Installation:
-
- Mount the drive on a vertical surface or DIN rail in a control cabinet, ensuring adequate airflow (minimum 100mm clearance above and below) for cooling.
-
- Install in a clean, dry environment away from direct sunlight, corrosive gases, and high-vibration equipment.
-
- Use a heat sink if operating at continuous current above 8A to prevent overheating.
- Wiring and Connection:
-
- Connect 3-phase 400V AC power to the L1, L2, L3 terminals, using a circuit breaker rated for 16A and twisted-pair cable with appropriate gauge (min. 2.5mm²).
-
- Wire the servo motor to the U, V, W output terminals, ensuring correct phase sequence to avoid reverse rotation.
-
- Connect feedback devices (encoder/resolver) to the dedicated feedback port, using shielded cable with the shield grounded at both ends.
-
- Link digital/analog I/O to sensors and actuators, configuring input type (PNP/NPN) via DIP switches.

- Configuration and Programming:
-
- Use Schneider Electric’s SoMove or MotionWorks IEC software to configure drive parameters (motor type, feedback type, control mode).
-
- Calibrate the motor using the auto-tuning function to optimize PID gains for the mechanical load.
-
- Set up safety parameters (STO activation threshold) and communication baud rate (default 125 kbps for CANopen).
-
- Test the drive in jog mode to verify motor rotation direction and feedback functionality before full operation.
- Operation and Maintenance:
-
- Power on the drive and check the status LED (green for ready; red for faults). Use the software to diagnose faults if indicated.
-
- Monitor key parameters (current, voltage, temperature) via the software dashboard during operation.
-
- Perform monthly inspections: check for loose connections, clean dust from cooling vents, and verify that STO functions correctly.
-
- Replace the cooling fan (if equipped) every 3-5 years to maintain thermal performance.
-
- Update firmware annually via software to access new control features and safety enhancements.
System Introduction
The ELAU C400/10/1/1/1/00 VCA07AAAA0AA00 operates as a critical power and control interface between motion controllers and servo motors, integrating four key layers:
- Power Conversion Layer: Converts 3-phase AC input to DC bus voltage, then to variable-frequency AC output to drive the servo motor, with high-efficiency (up to 96%) power conversion.
- Control Layer: Executes high-speed current, velocity, and position loops to maintain precise motor performance, using advanced algorithms to minimize settling time and overshoot.
- Safety Layer: Implements STO and protective functions to disable motor torque safely during emergencies, preventing unexpected motion.
- Communication Layer: Exchanges real-time setpoints and status data with the motion controller via CANopen, enabling synchronized multi-axis operation.
In a high-speed packaging line, the drive controls a servo motor that positions a film-cutting mechanism. The motion controller sends position setpoints via CANopen, and the drive adjusts motor torque and velocity to maintain ±0.1mm cutting accuracy at speeds up to 300 cuts per minute. Digital inputs from a photoeye trigger position corrections, while the analog output monitors motor current for predictive maintenance. The STO function integrates with the line’s emergency stop system, ensuring safe shutdown within 20ms of activation.
