R911255747 (KDA 3.2-050-3-D00-W1)

Description

The Bosch R911255747 (KDA 3.2-050-3-D00-W1) is an advanced drive controller, specifically engineered for the digital control of both 2AD series synchronous motors and 1MB frameless spindle motors, covering a rated output power range of 3-22 kilowatts. Employing a microprocessor for delivering drive control, conducting diagnostics, and overseeing constant monitoring, it provides an output rated current of 50 Amps and operates at a nominal DC bus voltage of 300V. The controller’s continuous current output stands at 35 Amps, drawing 1.2 Amps and 160 milliamps from +24 Volts and ±15 Volts inputs respectively. It supports a 16-bit parallel (digital) speed command value, although lacks encoder input and auxiliary interfaces. Use of a heatsink blower (requiring a 220V AC supply) ensures the controller stays cool. Operable in environments from 5 – 45 degrees Celsius, it can still function up to 55 degrees Celsius albeit with reduced nominal data. Its design adheres to the protection class IP10 (as per Din 40 050) and should only be operated by trained personnel.
