System compatibility

CDM1.4A belongs to Rexroth Indramat CDM motion control family,compatible with CCD control rack and CDB servo drives,matched with 2AD series servo motors,widely used in packaging machinery,robotics,textile machines and material handling equipment.This is a legacy spare part for industrial equipment maintenance replacement.

Function

CDM1.4A is a plug-in motion control module for Indramat multi-axis CNC system.It is installed inside CCD rack,executes motion program calculation,axis interpolation and logic control.It communicates with servo drives via SERCOS III bus,outputs motion commands and receives axis feedback signals to realize synchronized multi-axis movement.

Installation

Insert CDM1.4A into the designated slot of CCD control rack.Lock the module securely.Connect backplane bus and SERCOS communication cables.Check contact status and cable shielding before power-on commissioning.

Interface

‑24V DC backplane power supply

‑Dual RJ45 SERCOS III Ethernet port

‑Internal backplane bus connector

‑Shield grounding terminal

Circuit feature

High-speed motion calculation circuit,built-in bus signal isolation and surge suppression circuit,SERCOS real-time communication circuit,strong anti-interference,stable for multi-axis synchronous control.

Feature

CDM1.4A is obsolete Rexroth spare part.Typical faults:backplane contact failure,bus communication error,calculation chip damage,power circuit burnout.Inspect backplane connection and SERCOS communication function before replacement.Parameter backup is required before disassembly.

Diagnostic

When module fails,Power LED on,Run LED off,Error LED lit,SERCOS link cannot be established,axis initialization failure,motion program cannot execute,multi-axis communication timeout alarm.

Built‑in function:Motion interpolation calculation,SERCOS III real-time bus communication,multi-axis motion coordination,logic processing,program execution,used as Rexroth Indramat motion control system spare replacement.

Product Brief

CDM1.4A is Rexroth Indramat CDM series plug-in motion control module,fits CCD rack and works with CDB servo drives and 2AD servo motors.Verify rack slot compatibility and firmware version before ordering.ESD protection required during handling and installation.
