Product Description:

The KDA 3.2-150-3-A0S-U1 is a main spindle drive from the KDA series of Bosch Rexroth. It provides high quality precision and motion control performance in harsh industrial environments. The drive accepts an analog +/- 10V signal to provide fine adjustments to the speed regulation. It is suitable for high demand machinery and intricate automation as it combines reliability precision and flexibility.

The KDA 3.2-150-3-A0S-U1 spindle drive has a DC bus current of 300 V which is stable and continuous. It has forced cooling a heatsink fan and maintains the drive at the best temperatures. The operating temperature of the drive is between 0°C and 45 °C. This enables its use in a wide range of environments. It is also compatible with a broad humidity range of 5 % to 95 % as long as it is non condensing. The KDA 3.2-150-3-A0S-U1 spindle drive has IP10 protection that guarantees protection against dust and other particles. It is also engineered to work effectively at altitudes up to 1000 m and therefore makes it adaptable in diverse geographical settings. The drive has 150 A as the rated current and it can be used to control the operation of large machinery. It is also equipped with two LED indicators including a ready LED and a fault LED. This drive is designed to resist hard industrial conditions and deliver good performance in a range of applications.

The KDA 3.2-150-3-A0S-U1 spindle drive has an RS 232 C serial interface to communicate easily with other devices. It lacks an auxiliary encoder input making it simpler to install. The control buttons and the display panel are well labeled and thus are easy to use and operate. Its frequency range is 50 Hz to 60 Hz and the drive can operate on a 3 phase AC supply.
