Product Description:

The KDA 2.1-100-3-D0S-U1 is a Bosch Rexroth drive module designed for continuous operation in industrial motion control setups. This drive delivers high power capacity, allowing users to run high-torque spindle operations without thermal derating during extended cycles. The integrated air cooling system actively manages heat dissipation through forced air circulation so you don’t need external cooling infrastructure and can maintain optimal operating temperatures even under full load. This means you can run longer cycles without thermal speed reduction or protective shutdowns. The KDA series is designed for production environments where downtime is expensive.

The KDA 2.1-100-3-D0S-U1 has dual feedback options with resolver and tachometer capabilities so you have flexible position and speed sensing depending on your application requirements. Resolver feedback gives you absolute position information with high accuracy for applications that need precise spindle positioning and surface finish, while tachometer feedback is for less demanding operations. The drive's serial interface RS 232 C allows real-time communication with CNC controllers and monitoring systems so you can track spindle performance data, diagnose issues remotely and implement predictive maintenance. This reduces troubleshooting time by giving you operational status without having to open the drive enclosure.

The KDA 2.1-100-3-D0S-U1 has a panel mounting design that makes it easy to integrate into existing machine tool control cabinets and maximize space in enclosures with space constraints. The drive’s IP20 protection rating is sufficient for standard industrial environments, protecting internal components from accidental contact and debris. This protection level is matched to machine tool cabinet conditions where higher IP ratings would restrict airflow and cause thermal issues. With panel mounting users can position the drive optimally for heat dissipation and maintenance access.
