B&R 8V1320.001-2 Replacement for ACOPOS Series

Product Overview

B&R 8V1320.001-2 Replacement for ACOPOS Series: Smooth Migration from Legacy Servo Systems

Upgrading or replacing a B&R 8V1320.001-2 ACOPOS servo drive in an active production environment demands more than a simple part swap. Whether your existing 8V1320.001-2 has reached end-of-life, suffered a fault, or your engineering team is proactively migrating away from aging motion control infrastructure, this replacement solution is engineered to deliver a seamless transition with minimal disruption to your control architecture.

The B&R 8V1320.001-2 is a 16 kW single-axis servo drive from the ACOPOS family, designed for high-dynamic motion control applications in machine automation, packaging lines, printing systems, and precision assembly equipment. Its integration with B&R’s POWERLINK real-time Ethernet protocol and native compatibility with the Automation Studio programming environment makes it a cornerstone component in many legacy and current-generation B&R motion systems. Our replacement units are sourced, tested, and shipped from Xiamen with full functional verification prior to dispatch.

Seamless Upgrade Solutions

A successful migration of the 8V1320.001-2 rarely involves the drive unit alone. In most ACOPOS-based machine architectures, the servo drive operates as part of a tightly integrated motion system. During the replacement or upgrade process, engineers commonly address several adjacent components to ensure system-level compatibility and long-term reliability.

The 8V1090.001-2 ACOPOS servo drive (9 kW) is frequently found in the same control cabinet as the 8V1320.001-2, sharing the same POWERLINK node structure and Automation Studio axis configuration. When replacing the 16 kW unit, it is advisable to audit the 9 kW axis simultaneously to avoid a secondary unplanned outage. Similarly, the 8V1180.001-2 (18 kW variant) is sometimes used as an upgrade path when the application load has grown beyond the original 16 kW specification.

The 8AC114.60-1 ACOPOS plug-in module — commonly used for resolver or EnDat encoder interface expansion — should be inspected and replaced if the original unit shows signs of connector wear or firmware incompatibility with the new drive. Encoder signal integrity is critical during commissioning, and a degraded plug-in module can cause false encoder errors that are difficult to diagnose in the field.

Power supply integrity is equally important. The 8B0C0160HWS0.000-1 ACOPOS power supply module feeds the DC bus shared across multiple ACOPOS axes. If the bus capacitors are aged or the power module is approaching its service life, replacing it alongside the servo drive eliminates a common root cause of recurring DC bus undervoltage faults. The X20PS9400 X20 system power supply is often used in parallel to power the X20 I/O backplane within the same cabinet.

On the I/O side, X20AI4622 analog input modules and X20DI9371 digital input modules are typical companions in ACOPOS-integrated machine cells, providing process feedback signals to the motion controller. These modules connect via the X20 backplane and communicate through the same POWERLINK network segment as the ACOPOS drives. Verifying their firmware versions against the Automation Studio project version is a recommended pre-commissioning step.

For systems using a B&R APC910 or PPC800 industrial PC as the motion controller, the POWERLINK master configuration stored in the Automation Studio project must be validated after drive replacement. The node number assignment and cycle time settings for the 8V1320.001-2 axis must match the replacement unit’s configuration exactly to avoid network initialization errors at startup.

Finally, if the machine uses a B&R 4PP420 or 4PP065 Power Panel HMI for operator interaction, the axis status visualization and alarm pages linked to the ACOPOS drive should be tested after replacement to confirm that all drive status variables are correctly mapped and displayed. This is particularly important in systems where the HMI displays real-time torque, speed, and position feedback from the servo axis.

Retrofit Guidance FAQ

Q: Can I reuse the existing motor cable and encoder cable when replacing the 8V1320.001-2?
A: Yes. The replacement unit uses the same X2 motor power connector and X3 encoder interface pinout as the original. Provided the cables are in good condition and within specification, they can be reconnected directly without modification. Always perform an insulation resistance test on the motor cable before reconnecting to a new drive.

Q: Do I need to re-program the drive after replacement?
A: No re-programming is required if you restore the Automation Studio project backup to the replacement unit. The axis parameters, motion profile, and POWERLINK node configuration are stored in the project, not in the drive’s non-volatile memory. Use the Automation Studio “Transfer to Target” function after physical installation to push the configuration to the new unit.

Q: Is the POWERLINK node address preserved after replacement?
A: The POWERLINK node address is set via the rotary switch on the front panel of the ACOPOS drive. Set the replacement unit’s rotary switch to the same node number as the original before powering on the system. Mismatched node addresses will prevent the POWERLINK master from recognizing the drive during network initialization.

Q: Will the replacement unit fit in the same cabinet space?
A: Yes. The 8V1320.001-2 replacement unit has the same physical dimensions and mounting footprint as the original ACOPOS drive. No cabinet modification, additional DIN rail space, or bracket adaptation is required.

Q: What if my system uses a resolver instead of an EnDat encoder?
A: The ACOPOS drive supports both resolver and EnDat encoder types through the appropriate plug-in module (e.g., 8AC114.60-1 for resolver). Confirm that the plug-in module installed in the replacement drive matches the encoder type used by your servo motor before commissioning.

Q: How do I handle the DC bus discharge before removing the old drive?
A: Always wait a minimum of 5 minutes after disconnecting mains power before touching the DC bus terminals. The ACOPOS drive contains high-voltage capacitors that retain charge after power-off. Verify bus voltage is below 50 VDC using a calibrated meter before proceeding with removal.

Warranty Assurance

Every B&R 8V1320.001-2 replacement unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes a functional verification test including power-on self-test, communication interface check, and output stage verification. Units that do not pass pre-shipment testing are not shipped.

In the event of a warranty claim, TOPNLMS provides a replacement unit or repair service with a target response time of 3 business days from claim receipt. Warranty coverage includes manufacturing defects, component failure under normal operating conditions, and firmware-related issues attributable to the unit itself. Physical damage caused by incorrect installation, overvoltage events, or environmental contamination is excluded from warranty coverage.

For procurement teams requiring documentation, we provide a test report, packing list, and commercial invoice with each shipment. Export from Xiamen is available via DHL Express, FedEx International Priority, or sea freight for bulk orders. Lead time for in-stock units is typically 3–5 business days to most destinations.
