The R911270886 (DDC01.1-K150A-DS03-01) is a DDC Drive Unit manufactured by Rexroth Indramat. This air-cooled model is designed with an integrated bleeder resistor and provides high-resolution rotor positioning. It sets a standard motor noise emission with its rated current of 150 Amperes. As the first model of the first series, it uses a digital servo feedback system and hosts a SERCOS interface command communication module. This allows the drive to coordinate with SERCOS interface controllers via fiber optic cables. The unit has an integrated fault-protection system that severs power when a fault is detected, accompanied by extensive diagnostics via an alphanumeric display. Complete with a tunable dynamic brake, programmable error reaction, and built-in contactor for isolation, the R911270886 (DDC01.1-K150A-DS03-01) promises ease of service and solid performance.
