The Bosch Rexroth MPN R911250281 (TDM 4.3-030-300-W1) is a servo drive equipped with integrated feedback electronics for precise motion control in conjunction with a three-phase MAC motor. The drive features two differential inputs for set-point smoothing and supports master-slave configurations, with the slave speed controlled by the master speed controller. Upon detection of a malfunction, the power section is disconnected from the mains supply by a contactor for safety. The device accommodates an RF input voltage up to 3V, incorporates an internal fan for cooling, and is designed for a link circuit rated voltage of 300VDC. Insulation complies with Class C DIN VDE 0110 standards, and connections should adhere to specified cable types, lengths, and shielding requirements to ensure proper thermal management and signal integrity. The unit operates with a type current of 30A.
