Product Description:
The KDA Spindle Drives series carries this model number KDA 2.1-150-3-LY0-U1 produced by the famous brand Bosch Rexroth Indramat. As its cooling method employs forced air technique which sustains component temperatures under heavy loads. It delivers rated power that varies by application but usually matches the 150 A specification, guaranteeing an energy capacity alignment with drive current. The module accepts an input frequency of 50/60 Hz which combines with global mains standards and prevents frequency‑mismatch faults.
Control is translated between analog/digital mode that gives us the capability of flexible command integration to legacy and modern automation systems. The electrical enclosures are protected with a protection class of IP20 against solid debris and permitted airflow to flow through to leave them cool. This variant possesses a rated current of 150 A which delivers strong torque drive during heavy machining runs. Under the electrical configuration of 3 x 230/400 V AC, it shows the rated voltage and corresponds to typical 3-phase connections. Single channeling operation will make wiring easier and more specific to controlling specific spindles. Both resolver or encoder feedback options feeds accurate position information into the drive and increases motion accuracy.
There is an absence of built-in fieldbus due to its fieldbus interface LY0 that simplifies functionality of simple installations. The firmware version of KDA 2.1-150-3-LY0-U1 appears as U1 which ensures the latest control algorithms deploy immediately. Further, the drive’s physical footprint measures approx. 390 mm × 110 mm × 320 mm (WxHxD) of dimensions which fits standard control‑cabinet slots. The module finds its use as a spindle drive in CNC milling applications. It also enables spindle positioning with C‑axis operation on multi‑axis lathes and further supports direct‑drive grinding machines for high‑speed surface finishing.
