Product Description:

The HDS01.1-W025-R is a modular motion-control unit produced by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. Acting as a drive controller, it delivers regulated power and closed-loop commands to servo or main spindle drives, coordinating axis speed, torque, and positioning tasks in automated machinery and transfer lines. The unit is intended for rack-mounted drive systems where several axes are grouped in one cabinet and controlled from a common power structure. Its housing format and connector arrangement match other HDS modules, allowing consistent multi-axis installation with uniform wiring and diagnostics.

Thermal management is handled by a built-in air blower, which moves air across heat-generating semiconductor stacks to keep internal temperatures within a safe operating range during continuous demand. The housing has an IP10 rating under DIN 40 050, which helps prevent accidental finger contact with live parts while relying on the cabinet for dust protection. Continuous duty is supported within an ambient range of +5 °C to +45 °C, which suits typical factory conditions and supports normal production use without additional external ducting. The unit uses Class C insulation under DIN VDE 0110, allowing higher permissible thermal loading than lower insulation classes.

Full-load operation is permitted up to 1000 m above sea level; above this altitude, output current must be reduced in accordance with standard derating curves because thinner air lowers cooling effectiveness. The controller can also operate up to +55 °C with derating, which allows use in warmer enclosures when current demand is reduced. During storage or transport, the unit can withstand temperatures from -30 °C to +85 °C without operation, helping protect the electronics during warehouse handling or shipment. The product is Version 1.
