System compatibility

BG2-44 belongs to Rexroth Indramat control rack series,matching Indramat servo drives and servo motors with holding brakes,widely used in CNC machine tools,automated handling equipment and press control cabinets.This is a legacy spare part for industrial equipment maintenance replacement.

Function

BG2-44 is a plug-in brake control module.It receives release/lock logic command from servo amplifier,outputs driving power to servo motor holding brake coil.It realizes interlock control of brake and servo axis,ensuring brake releases only when servo is ready and locks automatically after power cut to prevent load dropping.

Installation

Insert BG2-44 into standard control subrack,tighten front panel fixing screws.Connect 24VDC power,servo logic signal and motor brake coil wiring according to wiring diagram.Check terminal connection and shield grounding before power-on commissioning.

Interface

‑24V DC power terminal

‑Brake coil output terminals

‑Servo logic signal terminals

‑Backplane bus connector

Circuit feature

Built-in relay and interlock circuit,brake action delay logic,over-current protection for brake coil,strong anti-interference,suitable for harsh workshop industrial environment.

Feature

BG2-44 is obsolete Rexroth spare part.Typical faults:brake drive circuit damage,logic signal failure,relay aging,backplane contact fault.Inspect brake output and interlock signal before replacement.This brake module must match original servo drive and motor brake specification,direct substitution without inspection is not recommended.

Diagnostic

When module fails,the brake cannot release normally or cannot lock after power-off,servo axis triggers brake interlock alarm,load slipping risk occurs.

Built‑in function:Servo motor holding brake drive,brake and servo interlock control,power-off load holding protection,used as Rexroth Indramat motion control system spare replacement.

Product Brief

BG2-44 is Rexroth Indramat rack plug-in brake control module for servo motor holding brake interlock control.Verify brake coil rating and servo interlock logic before ordering.ESD protection required during handling and installation.
