The original PacDrive MC-4 documentation identifies MC-4/11/22/400 V, order number 13 13 02 54, as the 22 A version. It specifies 380–480 VAC input, 24 VDC control supply, 530–680 VDC DC circuit voltage, 22 Aeff continuous current, 55 Aeff peak current for one second, and 15.2 kVA rated output.
The same technical documentation specifies a 42 Ω internal bleeder resistor, 150 W continuous bleeder power, and 15 kW peak bleeder power. The unit uses temperature-controlled internal fan cooling and is rated IP20 at the enclosure.
MC-4/11/22/400
Product Introduction
The ELAU MC-4/11/22/400 is a PacDrive MC-4 servo drive designed for three-phase servo motor control in ELAU PacDrive motion systems. Its 380–480 VAC power stage generates a 530–680 VDC internal bus and delivers up to 22 Aeff continuous motor current, with a documented 55 Aeff one-second peak rating. The drive is therefore a substantial motor power component rather than a low-power motion interface or PLC output module.
The MC-4 platform was used in machine automation applications where coordinated servo motion was handled through the PacDrive architecture. The exact drive-to-motor combination matters: motor parameters, feedback arrangement, controller configuration, firmware, and application settings all affect commissioning. The MC-4/11/22/400 is also identified by the material/order number 13 13 02 54, which is useful when cross-checking older machine documentation.
Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
The biggest replacement mistake with the MC-4/11/22/400 is matching only the 22 A current rating. The drive is part of a complete PacDrive motion system, so the replacement must also match the machine’s motor, feedback, control architecture, DC-bus arrangement, and stored drive parameters. A mechanically compatible drive can still require substantial commissioning work if its firmware or configuration does not match the original installation.
Typical Applications
- Multi-axis packaging machinery using ELAU PacDrive motion control.
- High-speed filling, labeling, pick-and-place, and material-handling equipment.
- Printing and converting machines requiring coordinated servo axes.
- Legacy machine platforms using PacDrive MC-4 servo amplifiers.
Technical Pitfalls to Avoid
- Do not confuse 22 A continuous current with motor horsepower. The documented rating is 22 Aeff and 15.2 kVA; actual motor compatibility depends on motor voltage, current, feedback, and the application duty cycle.
- Check the DC bus before servicing. The drive operates with a 530–680 VDC internal DC circuit. The documentation also specifies an 820 VDC bleeder-on threshold and 860 VDC excess-voltage level. This is high-energy equipment, not a low-voltage servo controller.
- Verify the braking/bleeder arrangement. The internal bleeder is specified at 42 Ω, 150 W continuous and 15 kW peak. Regenerative energy and braking behavior should be checked against the machine’s actual deceleration profile.
- Check the control supply separately from the motor supply. The MC-4 uses a 24 VDC control supply rated at 1 A. A correct mains connection does not compensate for an incorrect or unstable control supply.
- Verify cooling and cabinet airflow. The MC-4 uses an internal temperature-controlled fan. A blocked cabinet filter, failed fan, or excessive ambient temperature can cause problems even when the drive’s electrical ratings are within limits. The documented operating range is +5 to +45°C, with reduced-power operation permitted up to +55°C.
- Do not assume every MC-4 is equivalent. The MC-4 family includes different current and voltage configurations. Match the complete designation, not simply “MC-4.”
- Preserve drive parameters before replacement whenever possible. Motor identification, current limits, feedback configuration, acceleration/deceleration values, and controller communication settings can be just as important as the hardware number.

Procurement and Replacement Note
For procurement, specify ELAU MC-4/11/22/400, order number 13 13 02 54, and the installed drive’s hardware and firmware information. The electrical baseline to verify is 380–480 VAC, 48–62 Hz, 24 VDC control supply, 22 Aeff continuous output, 55 Aeff one-second peak, and 15.2 kVA.
Before installing a replacement, record the motor model, encoder/feedback type, PacDrive controller model, drive firmware, machine parameters, braking configuration, and cabinet cooling condition. For a legacy MC-4 installation, those details are more useful for successful commissioning than the drive part number alone.
