Product Description:
Bosch a trusted name in motion control technology, manufactures the KDA 2.1-150-3-DY0-W1 spindle drive. This drive is built to deliver consistent and efficient operation in demanding industrial settings. It features forced cooling by a heatsink blower to maintain stable operating temperatures. The heatsink operates with a 220V supply which confirms heat dissipation during continuous use.
The KDA 2.1-150-3-DY0-W1 spindle drive accepts a digital 16-bit parallel speed command value which allows precise spindle speed control. The KDA spindle drive supports auxiliary and synchronous encoder inputs such as 35 with speed command value input through channel A. It is powered by an AC supply source and operates with a DC bus voltage of 300 V. The device delivers an operating current of up to 150 A which meets power demands for various spindle tasks. The heatsink of this spindle drive is optimized for supply frequencies between 50 and 60 Hz which improves cooling performance. It can be mounted at altitudes up to 1000 meters without any reduction in nominal data. The protection class for the KDA 2.1-150-3-DY0-W1 drive is rated at IP10 according to DIN 40 050 for basic protection against solid objects.
The KDA 2.1-150-3-DY0-W1 spindle drive has a permissible ambient temperature range at nominal data is +5 to +45 °C and with a maximum of 55 °C allowed when nominal data is reduced. The spindle drive withstands storage and transit temperatures from -30 to +55 °C. It also meets humidity class F requirements as per DIN 40 040 for durability in moist environments. The drive offers reliable temperature management, precise control signals, and resilient electrical and environmental protection.
