The ELAU MC-4/11/22/400 is a higher-current single-axis servo drive for PacDrive machine automation systems. It is designed for servo axes that require more motor current than compact MC-4 versions while retaining the same integrated PacDrive drive architecture.
The unit combines the mains supply section, DC link, inverter output stage, internal braking circuit, and servo regulator in one cabinet-mounted module. With a rated output current of 22 Aeff and a one-second peak current of 55 Aeff, it is suitable for demanding positioning, indexing, synchronized conveying, and machine-axis applications.
Real-time drive commands are transmitted through the integrated SERCOS fiber optic interface from a compatible PacDrive controller. The drive also supports electronic motor nameplate recognition and single-turn or multi-turn encoder processing when used with matching PacDrive servo motors.
This model is a servo amplifier, not a motion controller, PLC, VFD, or energy-management device. Its function is to power and regulate one compatible servo motor axis within an established PacDrive system.

Installation Notes
Install the MC-4/11/22/400 inside a grounded control cabinet with adequate airflow.
Confirm that the three-phase mains supply is within the 380 to 480 VAC range and that the 24 VDC control supply is correctly wired.
Use compatible PacDrive fiber optic cables, servo motor cables, encoder connections, and inverter-enable wiring before commissioning.
At ambient temperatures above 45°C, output power must be reduced. Provide sufficient cabinet ventilation for stable operation.
