ELAU VPM01D16AA00 Retrofit-Ready Power Supply for PacDrive Control Systems
The ELAU VPM01D16AA00 — also referenced as PS-4/10/16/230/00 in legacy PacDrive documentation — is a dedicated power supply module engineered for the ELAU PacDrive automation platform. As production lines running original PacDrive controllers face end-of-life component shortages, the VPM01D16AA00 has become a critical retrofit solution for maintenance engineers and system integrators tasked with keeping packaging, printing, and converting machinery operational without a full platform migration.
This module delivers regulated DC power to the PacDrive servo drive rack, supporting the coordinated motion control architecture that PacDrive systems depend on. When the original PS-4/10/16/230/00 unit fails or becomes unavailable through standard distribution channels, a verified replacement sourced from specialist inventory — such as this unit — allows facilities to restore production with minimal engineering rework.

Retrofit Planning for Existing Automation Systems
A successful VPM01D16AA00 retrofit begins well before the replacement unit arrives on site. Engineers should first audit the existing PacDrive rack configuration, noting the positions of all installed modules: the MC-4 motion controller, any installed ELAU C400 servo amplifiers, the SERCOS fiber-optic ring connections, and the CANopen device network wiring. The power supply slot is typically located at the left end of the rack, and the DC bus connectors feeding downstream servo drives must be inspected for wear before the new module is seated.
Terminal wiring on the AC input side should be documented with photographs before disconnection. The VPM01D16AA00 uses the same terminal block layout as the original PS-4/10/16/230/00, so existing cable lengths and ferrule crimps can be reused directly — a significant time saving compared to a full platform migration. Verify that the upstream circuit breaker rating matches the module’s inrush current specification, particularly in facilities where the original installation predates current electrical standards.
On the control side, the PacDrive programming environment (PacDrive Designer or the legacy EPAS-4 software) does not require any project modifications when swapping a like-for-like power supply. The MC-4 controller retains its motion program, axis parameters, cam profiles, and HMI variable mappings in non-volatile memory, so the operator panel — whether a Schneider Electric Magelis HMI or a third-party touch panel connected via Modbus TCP — will resume normal display without screen reconfiguration.
If the retrofit is part of a broader system upgrade that also involves replacing ELAU servo motors (SH series) or adding I/O capacity through additional CANopen I/O modules, the power budget of the new supply should be recalculated to confirm headroom. Similarly, if the site is migrating communication infrastructure — for example, transitioning from a legacy SERCOS I fiber ring to a newer EtherCAT backbone — the power supply replacement is an ideal checkpoint to verify that all rack-level grounding and shielding practices meet the updated EMC requirements of the new network topology.
For facilities maintaining a mixed fleet of PacDrive and third-party motion platforms, it is worth confirming that the 24V DC auxiliary supply feeding external sensors, proximity switches, and safety relays is sourced independently of the VPM01D16AA00 rack bus output. This isolation ensures that a power supply swap does not inadvertently interrupt safety circuit continuity during the changeover window.
Downtime Control During System Migration
Minimizing unplanned downtime is the primary concern when replacing a power supply in a live production environment. The recommended approach is to schedule the swap during a planned maintenance window, with the replacement VPM01D16AA00 pre-inspected and bench-tested before it reaches the machine floor. Our pre-shipment testing protocol verifies output voltage regulation, inrush limiting, and thermal performance under load — so the unit arriving at your facility is confirmed operational before installation begins.
Before powering down the rack, use the PacDrive MC-4 controller’s diagnostic interface to capture a full axis parameter backup and export the current motion program to a USB drive or engineering workstation. This backup takes less than five minutes and provides a complete restore point if any unexpected configuration issue arises after the power supply is replaced. The EPAS-4 or PacDrive Designer project file should also be archived with a version timestamp.
During the physical swap, the SERCOS fiber-optic cables connecting the MC-4 to downstream C400 servo amplifiers should be handled carefully — fiber connectors are sensitive to contamination and should be capped immediately upon disconnection. Once the VPM01D16AA00 is seated and the AC input terminals are reconnected, the standard PacDrive startup sequence (controller boot → SERCOS ring initialization → axis enable) should proceed without deviation from the normal commissioning checklist.
In most documented retrofit cases, total downtime from power-off to first production cycle is under two hours when the replacement unit is pre-tested and the engineering team has completed the pre-swap documentation steps described above. For critical 24/7 production lines, we recommend keeping a spare VPM01D16AA00 in on-site inventory to reduce mean time to repair to under 30 minutes.
Retrofit Support FAQ
Q: Is the VPM01D16AA00 a direct replacement for the PS-4/10/16/230/00?
A: Yes. VPM01D16AA00 and PS-4/10/16/230/00 are the same ELAU power supply module referenced by two different part number conventions — the former is the component-level SKU and the latter is the system-level catalog designation. They are electrically and mechanically identical and are interchangeable without modification.
Q: Will I need to re-commission my PacDrive axes after replacing the power supply?
A: No full re-commissioning is required. The MC-4 controller stores all axis parameters, cam tables, and motion programs in non-volatile memory independent of the power supply. After the swap, a standard startup sequence and a brief jog test on each axis is sufficient to confirm normal operation before resuming production.
Q: What pre-shipment testing is performed on this unit?
A: Each VPM01D16AA00 is tested for correct output voltage, load regulation, and inrush current behavior before dispatch. Units are shipped with a test record. The 12-month warranty covers all electrical and mechanical defects from the date of shipment.
Q: What if my wiring gauge or terminal ferrule size differs from the original installation?
A: The VPM01D16AA00 uses standard ELAU terminal block specifications. If your site uses non-standard cable gauges due to a previous field modification, our technical team can advise on compatible ferrule sizes and torque specifications before you begin the swap.
