Product Description:

The KDA 3.1-100-3-DP0-W1 AC main spindle drive is part of the Series 3 drive modules developed by Bosch Rexroth. The spindle drive is designed for applications like medical technologies, printing and packaging, and woodworking machinery. The spindle drive delivers a rated current of 100A with a DC bus voltage of 300V.

The KDA 3.1-100-3-DP0-W1 AC main spindle drive is made with an ingress protection rating of IP10 in accordance with DIN 40 050. Spindle feedback is made possible via the drive's auxiliary encoder input. There is no provision in the design for the auxiliary interface. The heatsink blower is powered by an alternating current source that runs at 220V and 50-60Hz. Efficient signal processing is made possible by the drive module's digital 16-bit parallel speed command value. A blower system that uses a heatsink is used for forced cooling in the system. Within the temperature range of 0 to 45 degrees Celsius, the spindle drive operates efficiently. The non-condensing environment has a relative humidity tolerance of 5% to 95%. The technical design of the drive ensures reliability and interoperability with automation systems.

The KDA 3.1-100-3-DP0-W1 spindle drive integrates a design that supports reliable current delivery and digital control. The drive is constructed to function at a maximum installation altitude of up to 1000 meters without performance loss. The climatic category is Class F that provides stable operational characteristics. These specifications make the spindle drive suitable for controlled environments where consistent performance is required. The climatic category is Class F according to DIN 40 040. The drive is designed to meet defined standards and specifications. It delivers functions that align with professional application demands and operational requirements.
