Indramat AC main spindle drives are used to regulate the primary spindle motor in CNC machines, machining centers, lathes, grinders, and other automated production equipment. These drive systems convert electrical power into controlled spindle motion, helping the machine hold commanded speed, torque, orientation, and positioning accuracy during demanding cutting or production cycles.

For manufacturers working with legacy Bosch Rexroth Indramat systems, replacement and repair support is often the fastest way to reduce downtime without changing the entire CNC platform. Wake Industrial supplies and services Indramat spindle-drive families including KDA, KDS/KDW, TDA, RAC, HDS, and HDD units for customers who need fast quotes, replacement options, or professional repair support.

The KDA Series is a digital main spindle drive family built for CNC spindle control with high stiffness, broad speed range, and precise positioning capability. These drives are commonly used with Indramat 2AD asynchronous spindle motors and 1MB frameless spindle motors in machine-tool applications that require stable cutting performance across changing loads. KDA drives are suited for spindle positioning, C-axis operation, and high-accuracy speed regulation in legacy CNC systems. If a KDA unit fails, Wake Industrial can help source a replacement, review the full type code, or arrange repair service to keep the machine platform productive.

The Bosch Rexroth Indramat KDA 3.2-100-3-A00-U1 is a spindle drive in the KDA Spindle Drives series. It features a forced cooling system using a mounted heatsink blower and operates with a rated current of 100 Amps at a DC supply voltage of 300 VDC. The drive is designed for ambient temperatures from 5 to 45 degrees Celsius and can be installed up to 1000 meters above sea level.

The KDS and KDW drive modules are used in modular Indramat drive systems where fast response, cabinet-mounted installation, and controlled motor output are required. KDS units are often associated with servo-axis control, while KDW variants are used in spindle-oriented applications depending on the machine configuration. These modules are valuable in older CNC and automation systems because they can support precise speed or position control without requiring a full modernization project. Wake Industrial can help identify the correct KDS or KDW replacement by matching current rating, cooling style, voltage class, and complete type code.

The KDS1.1-50-300-W1/220 is a Bosch Rexroth Indramat KDS servo drive module for modular MAC servo drive systems. This configuration is a 50 A current-class unit with forced-ventilation cooling, external heat exchanger configuration, and a MOD programming module used to match the drive to the motor configuration.

The TDA Series is an Indramat main spindle controller family used for intelligent digital control of AC spindle motors in CNC machine tools. These controllers are designed for applications using 2AD asynchronous main spindle motors and 1MB frameless spindle motors, with support for low-speed precision, spindle orientation, and analog command interfaces. TDA controllers remain important in legacy machining centers because they combine compact construction with strong spindle-control capability. When replacing a TDA controller, the full type code, rated current, command value, cooling arrangement, and programming-module requirements should be reviewed before installation.

The TDA 1.1-100-3-A0I is a Bosch Rexroth Indramat main spindle controller for compatible 2AD asynchronous motors and 1MB frameless spindle motors. This configuration is listed with a 100 A rated current, 70 A continuous effective current, 300 V DC link rated voltage, and 10.5 kg weight. It uses an analog ±10 V speed command value for connection to an NC/CNC controller.

The RAC Series covers larger digital spindle drive controllers used in high-power CNC spindle applications. These drives are commonly found in machining centers, production lines, boring mills, and other equipment where the spindle must maintain torque and speed under heavy load. RAC controllers are built for demanding spindle operation and are available in many current, voltage, interface, and cooling configurations. Wake Industrial can assist with RAC replacement, repair, and type-code matching for facilities that need to keep high-horsepower Indramat spindle systems in service.

The RAC 2.2-150-380-A00-W1 is a Bosch Rexroth Indramat RAC main spindle drive controller for compatible 2AD asynchronous main spindle motors and 1MB frameless spindle motors. This configuration uses an analog ±10 V speed command and is listed without an additional encoder input.

The HDS Series is a single-axis drive controller family from the DIAX04 platform, designed for modular cabinet systems that require precise servo or spindle-related control. HDS controllers are commonly used in CNC machines, transfer lines, handling systems, packaging equipment, and other automated machinery where a single controlled motor axis must deliver dependable speed, torque, and positioning performance. In spindle-related applications, HDS units may be configured with command communication and firmware options that allow them to support demanding machine-tool functions. Many HDS controllers use SERCOS communication, internal air-blower cooling, and rated-current classes such as 75 A, 100 A, and 200 A depending on the complete type code. Because the HDS family includes many line, version, command, and firmware combinations, the full part number is critical when replacing a failed unit.

The Bosch Rexroth Indramat HDS03.2-W100N-HA01-01-FW is part of the HDS Drive Controllers series. It is a drive controller from the DIAX04 family with a rated current of 100 Amps and uses a built-in internal air blower for cooling. This model features an analog command communication interface.
