HDS02.1-W040N-HS37-01-FW
The HDS02.1-W040N-HS37-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Designed for multi-axis systems that use torque-controlled synchronous or asynchronous motors, the unit serves as the power stage between a higher-level CNC or PLC and the connected motors. In automated machinery, it converts DC-bus power into controlled motor current for coordinated axis motion. It supports closed-loop speed and position control so linked axes can maintain accurate movement during production. This role allows the drive to respond quickly to motion commands while maintaining stable torque delivery at the motor.
Inside the housing, a SERCOS fiber-optic channel handles real-time command and status data, so the controller can operate in synchronized multi-axis networks over a deterministic serial bus. The power section is rated for a continuous output of 40 A, which must be matched to the connected motor and cabling. Thermal management is provided by a built-in air blower that circulates cabinet air through the heat sink. This cooling method supports vertical mounting without external ducting. The unit is part of the DIAX04 family, which places it within the same drive platform as other compatible modules.
The unit is Version 1 and is assigned to Line 02 in the product range. Its classification as an HDS Drive Controller identifies it as the drive power and control section used in multi-axis assemblies. It works with companion supply and interface modules that share the same bus rails in the drive assembly. The line assignment indicates a medium-power option set for axis control, while the version designation refers to the established layout and connector arrangement for this model. These characteristics make the module suitable for coordinated drive systems that require stable communication, controlled current delivery, and consistent mechanical fit within the platform.
