Product Description:

The HDS02.2-W040N-HS84-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Designed for use in DIAX04 automation racks, the module amplifies and regulates motor phase current so that servo axes follow numerical-control commands with repeatable accuracy. Its role in industrial automation is to bridge the motion bus and the power stage, allowing coordinated multi-axis movement in equipment such as gantry loaders, printing lines, and machining centers. This arrangement supports synchronized motion where several axes must start, stop, and change speed in step with the machine program.

In operation, command data reach the unit through the SERCOS fiber-optic interface, providing cyclic position and diagnostic exchange with low latency. The drive can deliver a continuous output of 40 A, which is the maximum motor phase current it can supply continuously without overheating. Excess heat is removed by a built-in air blower, enabling stable thermal behavior inside a closed cabinet without external fans. Electrical safety is supported by Class C insulation per DIN VDE 0110, which allows higher internal temperature tolerance before insulation failure. The housing carries an IP10 protection category, so it blocks entry of larger solid objects but provides no liquid protection and is best installed in a clean, dry enclosure.

The controller is intended for installation up to 1000 m above sea level, so full current output is available in most factory settings. During operation, ambient air must remain between +5 to +45 °C; if temperatures rise further, the output current must be reduced once +55 °C is reached. When the equipment is stored or shipped, the electronics can withstand temperatures from -30 to +85 °C during nonoperating conditions. Adequate cabinet ventilation is still important when ambient temperatures approach the upper operating range.
