KDA 3.2-100-3-A0I-U1

KDA 3.2-100-3-A0I-U1, Bosch Rexroth Indramat, KDA Spindle Drives delivers precision motion control in a rugged, industrial-grade package engineered for high-speed spindle applications. This controller features an impressive Current Rated of 100 A and supports a Continuous Current of 70 A for sustained torque output. The unit operates from a Rated Voltage of 300 V DC, converting AC utility power into a stable DC bus through an integrated rectifier stage. Designed for seamless integration, the compact chassis accommodates forced cooling via a dedicated blower interface to manage thermal stress under heavy-duty cycling.

Engineered with flexibility in mind, the drive accepts a Rated Connection Voltage for attached Blower of AC 50–60 Hz and provides an analog Speed Command Value input of ±10 V for smooth speed regulation. The Aux. Encoder Input is configured without auxiliary interface modules to streamline signal routing when paired with standard incremental encoders. Internally, the drive’s power electronics and digital control boards reside within a galvanized steel housing dimensioned to industry benchmarks, labeled as Product KDA, Series 3, Design 2. Thermal monitoring and active regulation optimize performance over a broad ambient range, while real-time fault diagnostics and current feedback loops ensure rapid fault clearance and minimal downtime.

The KDA 3.2-100-3-A0I-U1 excels in machine tool, milling, and turning centers where reliable spindle speed stability and fast settling times are critical. Its native compatibility with Bosch Rexroth Indramat motion networks empowers multi-axis synchronization and adaptive torque control. The robust forced-air cooling and precision current control architecture guarantee long-term reliability, making it ideal for high-precision machining and demanding production environments.
