INDRAMAT TDM 1.2-100-300-W1-000

Overview

INDRAMAT TDM 1.2-100-300-W1-000 is a water-cooled modular AC servo amplifier from the Bosch Rexroth Indramat TDM 1.2 ANAX series. It works paired with TVM series DC bus power supply modules to drive Indramat MAC permanent magnet synchronous servo motors. It is widely supplied as exchange spare for CNC machine tools, heavy winders, extrusion lines and press automation control cabinet overhaul and drive replacement.

Features

INDRAMAT TDM 1.2-100-300-W1-000 is rated for 100 A output current on a 300 VDC bus; the W1 designation stands for water cooling, making it suited for continuous high-torque, high-duty-cycle heavy loads. It uses analog ±10 V speed or torque reference, with resolver feedback for closed-loop position and speed regulation. It relies on the dedicated personality module for motor parameter and loop gain configuration, which simplifies commissioning for matched MAC motors.

INDRAMAT TDM 1.2-100-300-W1-000 integrates standard drive protection including overcurrent, DC bus overvoltage, undervoltage, resolver fault, motor short circuit and overtemperature protection for the power stage. Onboard LED indicators show power, enable, fault and resolver status for fast on-site diagnostics. This legacy analog drive does not support fieldbus; all tuning is set via the personality module and potentiometers. It is designed for heavy industrial vibration and continuous-duty operation.

Specs

INDRAMAT TDM 1.2-100-300-W1-000Platform: Indramat TDM 1.2 ANAX servo system Type: water-cooled servo amplifier module Catalog number: TDM 1.2-100-300-W1-000 DC bus: 300 VDC Output current: 100 A Cooling: water cooled (W1) Feedback: resolver Control reference: ±10 V analog Matching power supply: TVM series power supply module Motor compatibility: Indramat MAC series servo motors Mounting: chassis mounting inside drive cabinet Protection rating: IP20 This is not a power supply, motor or PLC; it is the stand-alone servo power amplifier for the TDM modular motion system. INDRAMAT TDM 1.2-100-300-W1-000 is widely supplied as service replacement spare for heavy-duty servo motion control failure.

Principle

INDRAMAT TDM 1.2-100-300-W1-000 receives stabilized DC power from the TVM supply module. The IGBT inverter bridge converts DC into three-phase variable-frequency PWM output to drive the MAC servo motor. The resolver continuously feeds back rotor position and speed. The drive compares feedback against the analog reference and adjusts PWM output to maintain target speed or torque. If current, voltage or temperature exceeds limits, the amplifier disables output and latches a fault code.

Applications

INDRAMAT TDM 1.2-100-300-W1-000 is deployed for heavy CNC axes, extrusion main drives, paper winders, metal forming presses and high-load material handling machinery. It is selected for spare inventory and drive cabinet retrofit projects for existing Indramat TDM ANAX motion platforms.
