B&R 8AC120.60-1 Replacement for ACOPOS Series

Product Overview

B&R 8AC120.60-1 Replacement for ACOPOS Series: Seamless Migration from Legacy Servo Systems

The B&R 8AC120.60-1 is a plug-in axis module designed for the ACOPOS servo drive platform, one of B&R Automation’s most widely deployed motion control architectures in packaging, printing, and precision manufacturing. As legacy ACOPOS installations age and original modules reach end-of-life, sourcing a verified replacement for the 8AC120.60-1 becomes a critical path item for maintenance engineers and procurement teams alike. TOPNLMS stocks this module and ships globally, with each unit passing pre-shipment functional verification and covered by a 12-month replacement warranty.

Whether your facility is running a multi-axis ACOPOS rack with an 8AC110.60-1 or 8AC122.60-1 base drive alongside plug-in axis modules, or integrating the 8AC120.60-1 into a broader B&R Automation Studio motion project, this replacement module is engineered to slot directly into the existing hardware architecture without requiring rack modifications or firmware re-flashing in most standard configurations.

Compatibility Comparison Table

Seamless Upgrade Solutions

A successful migration from a failed or end-of-life ACOPOS axis module rarely involves a single component. In practice, field engineers replacing the 8AC120.60-1 often simultaneously audit adjacent hardware to prevent cascading failures. The 8AC110.60-1 ACOPOS base drive is the most common host unit for this plug-in module and should be inspected for DC bus capacitor health during any axis module swap. If the base drive itself is flagged, a parallel replacement order prevents a second unplanned shutdown.

On the motion feedback side, the encoder and resolver interface cables connecting the servo motor to the ACOPOS module — typically routed through 8BCF0000H0000.000-1 feedback connectors or equivalent B&R cable assemblies — should be continuity-tested before the new module is powered up. A damaged feedback cable is a frequent root cause of axis module faults that are misdiagnosed as module failures.

For facilities running X20 or X67 I/O modules in the same control cabinet, the POWERLINK network topology should be verified after the axis module replacement. The X20BC0083 POWERLINK bus controller or equivalent gateway module manages cycle-time synchronization across all POWERLINK nodes, and any change to the drive segment may require a network re-scan in Automation Studio. Similarly, if the machine uses a B&R Power Panel or Automation Panel HMI for operator interaction, the axis configuration display should be validated post-commissioning to confirm correct axis mapping.

In larger multi-axis systems, the 8B0C0160Hxxx.000-1 ACOPOS multi-axis inverter or 8BVI servo inverter modules may share the same DC bus infrastructure. Replacing the 8AC120.60-1 plug-in module in such architectures requires confirming that the DC bus pre-charge sequence and inrush current limits remain within the base drive’s rated parameters. A B&R 0PS series power supply module providing 24 VDC logic power to the ACOPOS rack should also be load-tested if the cabinet has experienced repeated power anomalies.

For sites migrating from older ACOPOS 1010 or ACOPOS 1016 base drives to current-generation hardware, the 8AC120.60-1 plug-in axis module remains compatible across the ACOPOS product family, making it a viable bridge component during phased modernization programs where full drive replacement is deferred to a later maintenance window.

Retrofit Guidance FAQ

Q: Can I replace the 8AC120.60-1 without modifying existing motor wiring?
A: Yes. The plug-in axis module interfaces with the motor through the ACOPOS base drive’s motor output terminals. The module itself does not have direct motor wiring connections, so no rewiring is required at the motor end.

Q: Do I need to re-upload my Automation Studio project after replacing the module?
A: In most cases, no. If the replacement module carries the same hardware revision, the existing project configuration is retained on the base drive. However, B&R recommends performing a hardware configuration comparison in Automation Studio after any module swap to confirm parameter consistency.

Q: Is the 8AC120.60-1 compatible with POWERLINK and CAN communication simultaneously?
A: The communication protocol is determined by the base drive and system configuration, not the plug-in axis module. The 8AC120.60-1 is passive in terms of network protocol selection and will operate correctly in both POWERLINK and CAN-based ACOPOS topologies.

Q: What physical space does the module require in the cabinet?
A: The 8AC120.60-1 occupies a standard ACOPOS plug-in slot. No additional DIN rail space or cabinet modification is needed. Verify that the target slot in the base drive is unoccupied and undamaged before installation.

Q: How do I verify the module is functioning correctly after installation?
A: Power up the ACOPOS base drive and observe the module status LEDs. Use Automation Studio’s online diagnostics to confirm the axis is recognized and no fault codes are active. Run a low-speed jog cycle before resuming full production.

Warranty Assurance

Every 8AC120.60-1 shipped by TOPNLMS is subject to a pre-shipment inspection protocol that includes visual examination, connector integrity check, and functional power-on verification where applicable. Units are packed in anti-static ESD-safe packaging with foam cushioning to prevent transit damage.

All orders are covered by a 12-month replacement warranty from the date of delivery. If a unit exhibits a defect or fails to perform to specification within the warranty period, TOPNLMS will arrange a replacement shipment at no additional cost. Warranty claims are processed within 2 business days of fault confirmation.

Expedited shipping options are available for emergency breakdown situations. Standard lead time from confirmed order to dispatch is 1–3 business days for in-stock units. Tracking information is provided upon shipment, and partial orders or split shipments can be arranged for large-quantity procurement requirements.
