HDS03.2-W100N-HT84-01-FW
The HDS03.2-W100N-HT84-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is intended for multi-axis industrial automation systems where a CNC or PLC sends higher-level motion commands to servo or induction motors. The unit converts supply energy into controlled three-phase output so speed, position, and torque can be regulated through closed-loop operation. Internal diagnostics and parameter memory keep operating data available for the control system, which supports consistent axis response during repeated production cycles. That makes the controller suitable for machine sections that require repeatable starts, stops, and speed changes throughout the workday.
Real-time commands and status data are exchanged through the SERCOS optical ring, which gives the drive a deterministic communication path within coordinated motion systems. The unit is part of Line 03, matching the physical size and current path used with the associated supply section in the same platform. Rated output current is 100 A, so the controller can support demanding acceleration and braking duty within its intended load range. Heat is removed by a built-in air blower that moves cooling air across the power section, reducing the need for external thermal hardware around the module. Because communication and power control are handled in the same unit, the module serves as the regulation stage for individual axes inside a shared drive system.
The controller is in Version 2 of the DIAX04 platform, indicating the later release used for this drive type. During operation, it closes current and velocity loops internally by using pulse-width modulation together with digital feedback from the motor system. This control method helps the module deliver commanded torque with stable response when several axes operate in sequence or in synchronization. The controller also retains parameter data internally, so stored settings remain available after normal power cycling. Its control structure regulates motor behavior inside the drive, which keeps fast current-control tasks local to the power stage.
