CDR2 109-0698-2A01-04

The Bosch Rexroth Indramat CDR2 109-0698-2A01-04 from the KDA Spindle Drives series is a precision-engineered main spindle drive designed for demanding industrial motion applications. Built by Bosch Rexroth Indramat, this KDA mainboard features a series type 3 and design type 2 architecture that ensures compatibility with KDA3.2-050-3-A00-W1 spindle systems. The unit delivers a robust 50 A current rating and operates on a 300 V DC bus voltage to drive high-inertia spindle loads with smooth dynamic response. Backed by a one-year warranty period, this drive module provides reliable performance and world-wide shipping support through established Bosch delivery networks.

Engineered for continuous operation in sealed control enclosures, the spindle drive accepts an analog ±10 V voltage rating for precise speed and torque control. It incorporates a dedicated 220 VAC supply for its heat sink blower to facilitate forced cooling via a high-efficiency heatsink blower assembly. The drive maintains optimal thermal conditions across an operating temperature range of +5 °C to +45 °C, with tolerance up to +55 °C for peak ambient loads. With no auxiliary interface or auxiliary encoder onboard, the simplified I/O configuration minimizes potential fault points and streamlines integration with standard CNC controllers.

Fault detection and diagnostics are performed via the integrated keypad display, which immediately indicates any drive brake or system malfunction and triggers a complete shutdown for operator safety. The drive’s forced-cooling mechanism and sealed housing design protect internal electronics from contaminants and ensure long-term reliability. Ideal for applications including food packaging machinery, machine tools, printing presses, material handling systems, and assembly lines, the CDR2 109-0698-2A01-04 offers a compact, high-performance solution for critical spindle drive requirements.
