System compatibility

608820103 belongs to Rexroth servo tightening system family,matched with tightening spindle and controller modules.Widely applied in automobile assembly tightening workstations.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

608820103 serves as Rexroth servo tightening system drive board.It receives motion control commands from the main controller and outputs power drive signals to the tightening servo motor.It collects motor current feedback and participates in torque closed-loop control during fastening process.It integrates overcurrent,overtemperature and overload protection functions.It uploads running state and fault codes to upper control unit in real time.It acts as power drive core component for Rexroth tightening workstation.

Installation

Install 608820103 to designated slot and lock fasteners.Complete power and motor wiring according to wiring drawing.Check 24V power polarity and equipment grounding before power-on.

Interface

‑24Vdc power input terminal

‑Servo motor power & encoder terminal block

‑Internal bus connector

‑Status and fault LED indicator

Circuit feature

Built-in ESD and surge suppression circuit,power loop isolation design,strong anti-interference performance for workshop industrial environment.

Feature

608820103 is obsolete Rexroth series spare part.Typical failures include motor no output,overcurrent alarm,torque out of tolerance,connector pin oxidation.Check circuit board,power loop and connector pins before replacement.This board must match corresponding Rexroth tightening servo system,direct substitution without inspection is not recommended.

Diagnostic

When overcurrent,overheat or internal hardware fault occurs,the module triggers protection and lights up fault LED.

Built‑in function:Servo motor power driving,torque closed-loop regulation,overload protection,status monitoring,self-diagnosis and fault alarm,used as Rexroth servo tightening system spare replacement.

Product Brief

608820103 is Rexroth old servo drive board for tightening assembly workstation.Confirm compatibility with corresponding tightening spindle and controller before ordering.ESD protection required during handling and installation.
