Product Description:

The HDS15.2-W300N is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It links the supply module to multiple servo axes, shaping current, supervising faults, and executing torque commands in automated assembly lines, presses, and material-handling cells. This control function lets connected motors respond quickly to changing load demands while maintaining stable torque and speed behavior. It is suited to multi-axis systems that require coordinated current delivery from a shared supply arrangement. The unit is version 2 and is intended for cabinet installation where precise current regulation supports repeatable motion profiles.

Under nominal conditions, the controller delivers a rated output of 300 A. Its closed-loop regulator maintains a continuous RMS value of 123.7 A, and the power section switches at 4000 Hz to support smooth torque control and reduced motor ripple. Thermal operation is based on an unrestricted ambient temperature of +45 °C, and a built-in internal air blower directs heat away from the 20 W signal electronics and the main semiconductors. The housing has an IP10 protection rating, so the unit must be installed inside a closed electrical cabinet. Operation is also limited to 1000 m above sea level to avoid thermal derating and reduced cooling performance.

During dynamic events, the drive can supply a peak current of 212.1 A for short acceleration demands before returning to steady-state operation. Internal losses can reach 1200 W at maximum throughput, and a derated ambient limit of +55 °C applies when cabinet ventilation is restricted. The controller weighs 25 kg, so the mounting structure must support its mass securely inside the cabinet. Storage and transport temperatures range from -30 °C to 85 °C, while permitted operating temperature remains between 5 °C and 45 °C. These temperature limits describe powered operation separately from non-operating handling and storage conditions.
