System compatibility

128MB belongs to Rexroth Indramat servo drive system family,matched with DKC/DDS series servo main control board.Widely applied in CNC machine tools,automation assembly,press-fit and material handling workstations.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

128MB is Rexroth Indramat servo drive memory card.It stores servo axis parameters,motion control programs,motor characteristic data and configuration backup files.It retains stored data when servo drive power is off.It exchanges data with servo mainboard through internal bus for parameter loading and saving.It prevents parameter loss caused by mainboard battery failure.It acts as external data storage component for Indramat servo drive unit.

Installation

Insert 128MB into memory slot on servo control board.Make sure direction is correct and fully seated.Restart servo drive and perform parameter backup verification.

Interface

‑Memory gold finger contact

‑Status indicator pin

Circuit feature

Built-in ESD protection circuit,non-volatile storage design,strong anti-electromagnetic interference performance for industrial workshop environment.

Feature

128MB is obsolete Rexroth spare part.Typical faults:data read/write failure,data loss,gold finger oxidation,storage chip damage.Inspect gold finger and test data readout before replacement.This memory card must match corresponding Indramat servo drive model,direct substitution without inspection is not recommended.

Diagnostic

When storage chip failure or contact poor occurs,the servo drive will report memory read error alarm.

Built‑in function:Motion parameter storage,program backup,offline data retention,status monitoring,self-diagnosis and fault alarm,used as Rexroth Indramat servo drive system spare replacement.

Product Brief

128MB is Rexroth Indramat old 128MB memory card for CNC machine tool and automation workstation.Confirm servo drive compatibility before ordering.ESD protection required during handling and installation.
