BACHMANN ISI222 Replacement Solution for ISI Series

Product Overview

BACHMANN ISI222 Replacement Solution for ISI Series: Smooth Migration from Legacy Motion Control Systems

The BACHMANN ISI222 is a high-performance positioning module designed for the ISI Series motion control platform. As industrial facilities transition away from aging or discontinued motion control architectures, the ISI222 serves as a reliable drop-in replacement and upgrade path for engineers managing servo axis coordination, cam profiling, and multi-axis synchronization tasks within BACHMANN-based control cabinets.

Whether your facility is retiring an older ISI Series rack configuration or replacing a failed positioning card in a live production line, the ISI222 offers a proven migration route that minimizes engineering rework, preserves existing wiring infrastructure, and maintains compatibility with the BACHMANN system bus. This module is particularly well-suited for applications in packaging machinery, printing presses, textile equipment, and precision assembly lines where axis positioning accuracy and deterministic cycle times are non-negotiable.

Seamless Upgrade Solutions

A successful ISI222 migration rarely involves a single module swap. In practice, engineers upgrading from a legacy BACHMANN ISI Series rack will also evaluate adjacent components to ensure system-wide compatibility. The BACHMANN MX213 CPU module, which serves as the central controller in many ISI-based cabinets, typically remains in service during an ISI222 swap — its firmware and task configuration require no modification when the positioning module is replaced on a like-for-like basis.

For facilities where the existing BACHMANN DIO216 digital I/O module handles limit switch and encoder feedback wiring, the ISI222 integrates directly without signal conditioning changes. Similarly, if your control cabinet includes a BACHMANN AIO288 analog I/O module for velocity reference or torque feedback signals, the existing wiring harness and terminal block assignments are preserved.

Communication infrastructure is equally straightforward. Sites running CANopen fieldbus between the BACHMANN rack and servo drives — such as those using BACHMANN-compatible CANopen gateway modules — will find that the ISI222 maintains the same node addressing and PDO mapping conventions as its predecessor, eliminating the need for network reconfiguration. For installations using PROFIBUS DP as the upstream communication layer to a supervisory SCADA or DCS, the BACHMANN DP master module in the same rack continues to operate without modification.

Power distribution within the control cabinet also remains unchanged. The BACHMANN PS204 power supply module, commonly installed in ISI Series racks, delivers the 24 VDC backplane voltage that the ISI222 requires — no additional power rail or fusing changes are necessary. If your retrofit also involves updating the HMI layer, BACHMANN-compatible operator panels with Ethernet connectivity can be integrated alongside the ISI222 without impacting the positioning module’s axis task execution.

For multi-axis applications requiring expansion beyond two channels, the ISI222 can be paired with additional ISI Series motion modules in the same rack, sharing the backplane bus and synchronized via the BACHMANN real-time operating system. Terminal modules and signal isolators used for encoder line driver signals remain compatible, protecting the existing field wiring investment.

Retrofit Guidance FAQ

Q: Can I replace the legacy positioning module without rewiring the servo drive connections?
A: Yes. The ISI222 uses the same connector pinout and backplane interface as the ISI Series predecessor modules. Existing servo feedback cables, encoder wiring, and digital I/O terminations connect directly without modification.

Q: Do I need to rewrite my IEC 61131-3 motion programs?
A: In most cases, no. The ISI222 is recognized by BACHMANN SolutionCenter using the same function block library. Axis configuration parameters (velocity limits, acceleration ramps, cam tables) are retained in the project file and download to the replacement module without structural changes.

Q: Is the CANopen node address preserved after module swap?
A: Yes. The CANopen node ID is configured in software via SolutionCenter and is stored in the project, not in the module hardware. After installing the ISI222, the node address is restored on the next project download.

Q: Will the ISI222 fit in the existing rack without mechanical modification?
A: The ISI222 occupies a standard ISI Series rack slot. No additional mounting hardware, spacers, or cabinet modifications are required. The module weight of approximately 240 g is within the rack’s rated slot load.

Q: What is the recommended commissioning procedure after installation?
A: Power down the rack, remove the legacy module, insert the ISI222, restore power, download the existing SolutionCenter project, and perform a controlled axis reference run. No additional calibration is required for standard servo axis applications.
