System compatibility

109-525-3201A-8 belongs to Rexroth Indramat servo drive system family,matched with DKC/DDS series servo drive 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

109-525-3201A-8 is Rexroth Indramat servo drive memory expansion board.It expands data storage capacity of the servo controller for motion programs,axis parameters and motor characteristic data.It stores backup configuration data to prevent parameter loss after power failure.It communicates with main control board through internal bus for high-speed data reading and writing.It ensures stable data storage during continuous high-speed motion operation.It acts as data storage expansion component for Indramat servo drive unit.

Installation

Install 109-525-3201A-8 into servo drive designated slot and lock fasteners.Connect internal bus connector according to wiring drawing.Check 24V power polarity and equipment grounding before power-on.

Interface

‑24Vdc power input terminal

‑Internal drive bus connector

‑Status and fault LED indicator

Circuit feature

Built-in ESD and surge suppression circuit,data protection design,strong anti-electromagnetic interference performance for industrial workshop environment.

Feature

109-525-3201A-8 is obsolete Rexroth spare part.Typical faults:parameter loss,data read-write error,connector pin oxidation,PCB circuit damage.Inspect circuit board and connector pins before replacement.This board must match corresponding Indramat servo drive mainboard,direct substitution without inspection is not recommended.

Diagnostic

When memory chip failure or bus communication abnormality occurs,the module triggers protection and lights up fault LED.

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

Product Brief
