Product Details

Baumuller 3.1503A, revision 01.00, is a dedicated motion expansion board and auxiliary control PCB designed for legacy Baumuller modular servo drive platforms. This motion expansion board extends the native control capacity of the main CPU, handling auxiliary motion sequencing, auxiliary setpoint calculation and coordinated logic for synchronized multi‑axis operations. The auxiliary control PCB carries dedicated DSP logic, extra parameter storage and additional signal routing circuits to offload routine motion tasks from the main control board. This revision 01.00 is the original baseline version with fixed firmware logic, standardized channel mapping and stable timing parameters validated for retrofitting old drive racks. The multi‑layer FR4 circuit board is conformal coated to protect sensitive signal traces against dust, moisture and corrosive vapors inside industrial control cabinets. As an obsolete and hard‑to‑source discontinued spare, it is a required drop‑in replacement for systems that rely on this exact revision to restore extended motion sequencing and auxiliary control functions.

Basic Parameters

Supported Functions

This motion expansion board supports auxiliary motion sequencing and synchronized auxiliary control for complex automation lines. The auxiliary control PCB receives command triggers from the main control board, executes predefined auxiliary motion sequences and feeds calculated auxiliary setpoints back for closed‑loop regulation. It stores dedicated motion profile parameters and logs sequence‑related faults for maintenance diagnosis. It works cooperatively with the main control board, encoder interface board and gate drive board to realize multi‑axis synchronous actions and auxiliary positioning tasks. If this extended control card fails, the drive will lose supplementary motion sequencing, report expansion module faults and cannot run configured coordinated motion programs.

Core Functions

The core function of this motion expansion board is to provide dedicated auxiliary motion processing extension for the servo drive controller. It expands the drive’s motion programming capacity and undertakes auxiliary sequence control to reduce the calculation load of the main CPU. It preserves original baseline timing and logic defined by revision 01.00 for legacy machine compatibility. This auxiliary control PCB acts as an essential spare to rebuild extended motion control capability for legacy motion machinery and retain the original machine motion sequence performance.
