Product Description:

This KDA 2.1-150-3-DPI-U1 main spindle drive manufactured by Bosch Rexroth Indramat has user-specific standard parameter values. The drive deploys the same process to input and change parameters as other drives in the same series. This product’s operating data mentioned on the rating plate must match that of the motor. The device needs individual grounding in a drive system. This unit has two bus bars for the DC bus link connection. It has identical NC and feedback connections like other spindle drives. The drive’s internal connections make it suitable for various control enclosures.

This product’s voltage must be switched off before changing the AS programming module. The device can be equipped with air filters to provide clean air. This unit dissipates heat outside its control enclosure. Its external heat dissipation and internal heat loss depend on the workload. The drive’s NC and feedback connection cables depend on its options. This product supports three categories of electrical connections. The device uses a bus connection cable for its DC link bus. Its fault codes must be reset after clearing the faults during operation.

The drive’s load voltage is rated at +24 V. The product also has a +/-15 V measuring voltage. The device’s storage is allowed only in a cool and dry place. This unit incorporates an incremental encoder output. Its peak operating temperature must not be higher than 55 °C at any point in time. The main spindle drive is protected from large objects, but not against the penetration of small objects and deliberate penetration by hand.
