System compatibility

0-608-701-018 belongs to Rexroth 350 tightening system family,matched with tightening drive,controller and torque transducer.Widely applied in automobile assembly bolt tightening workstations.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

0-608-701-018 is Rexroth EC304 high performance servo motor for electric nutrunner.It provides rotary power for bolt fastening operation.The built-in high-resolution encoder feeds back rotation angle and speed signal to tightening controller.It supports high dynamic torque closed-loop control to guarantee assembly precision.It monitors winding temperature and current overload continuously and sends fault alarm to control unit.It acts as core power execution component of Rexroth nutrunner spindle.

Installation

Install 0-608-701-018 into spindle housing and lock fixing fasteners.Connect motor power cable and encoder cable according to wiring drawing.Check equipment grounding before power-on.

Interface

‑3 phase AC power terminal

‑Encoder signal connector

‑Temperature sensor terminal block

‑Status and fault LED indicator

Circuit feature

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

Feature

0-608-701-018 is obsolete Rexroth spare part.Typical faults:motor no rotation,encoder signal loss,overcurrent alarm,torque output deviation,winding aging.Inspect motor winding,encoder and connector pins before replacement.This servo motor must match corresponding Rexroth tightening controller and drive system,direct replacement without inspection is not recommended.

Diagnostic

When overload,overheat,signal loss or internal hardware fault occurs,the motor triggers protection and lights up fault LED.

Built‑in function:Rotary power output for bolt tightening,angle and speed feedback,overload & overheat protection,status monitoring,self-diagnosis and fault alarm,used as Rexroth servo tightening system spare replacement.

Product Brief

0-608-701-018 is Rexroth EC304 servo motor for electric nutrunner assembly workstation.Confirm compatibility with matched tightening controller and drive before ordering.ESD protection required during handling and installation.
