The Bosch Rexroth digital servo drive, MPN R911271281 (DKS01.1-W050A-RL05-01-FW), is engineered for flexible integration in automation systems. It supports plug-in modules serving as I/O interfaces, high-resolution position interfaces, or incremental position interfaces. The drive operates at a frequency of 50-60 Hz, with a maximum drive loading power of 9.5 kVA and an input voltage of 3 x 230 VAC (+/-10% tolerance). It features an H1 display for diagnostic error and warning notifications and offers configuration labeling for the basic unit, software module, and installed plug-in cards. The unit has a rated current of 50 A and incorporates heat dissipation cooling, standard noise emission, and protection via power shut-off and programmable error reaction. Additional features include integral holding brake control, integral dynamic braking for deceleration and stopping, and security through monitoring contact openings below 200 V DC bus voltage or if continuous bleeder power reaches 80% of continuous feeder power. The product must be protected from water penetration and condensation to maintain functionality.
