System compatibility

ADM1.2-100-300-W1 belongs to Rexroth Indramat ADM servo drive family,matching Indramat synchronous servo motors,widely applied in CNC machine tools,presses and automated production lines.This is a legacy spare part for industrial equipment maintenance replacement.

Function

ADM1.2-100-300-W1 is a digital servo amplifier.It receives position and speed commands from upper CNC controller,converts DC bus power into adjustable three-phase AC power to drive servo motor.It realizes closed-loop position,speed and torque control for machine axes.

Installation

Install ADM1.2-100-300-W1 inside electrical cabinet rack,tighten fixing bolts.Connect DC bus cable,motor power cable and encoder feedback cable according to wiring diagram.Check wiring and grounding before power-on commissioning.

Interface

‑DC bus power terminal

‑Motor power output terminal

‑Encoder feedback connector

‑System backplane bus connector

‑Digital I/O terminal block

Circuit feature

High-speed current loop control,built-in over-current,over-voltage,over-temperature protection,stable dynamic response,strong anti-interference for industrial workshop environment.

Feature

ADM1.2-100-300-W1 is obsolete Rexroth spare part.Typical faults:power module burnout,bus fault,encoder port damage,circuit aging.Inspect power module and feedback channel before replacement.This servo amplifier must match original motor and control system,direct substitution without inspection is not recommended.

Diagnostic

When drive module damaged or feedback abnormal occurs,the system will trigger overcurrent,overvoltage or position tracking alarm,axis cannot run normally.

Built‑in function:Three-phase power conversion,servo motor closed-loop motion control,overload protection,used as Rexroth Indramat motion control system spare replacement.

Product Brief

ADM1.2-100-300-W1 is Rexroth Indramat ADM series rack servo amplifier for CNC axis motion control.Verify DC bus rating,motor matching and encoder signal before ordering.ESD protection required during handling and installation.
