R911289021
The R911289021 (PPC-R02.2N-N-L2-NN-NN-FW), a multi-functional CNC control unit, is a highly reliable device from the renowned Bosch Rexroth Indramat. This device is noted for its versatility - it can be used either as a programmed logic controller or NC controller, depending on specific need. With ingress protection category IP 20, this device is impervious to intrusion by any object larger than 12.5 mm. The control unit facilitates data transfer via RS485, RS232, and RS422 serial interfaces. Usually housed in a switch cabinet, this device incorporates a lithium battery to buffer its SRAM and system clock, and stores important NC data such as machine parameters, tool data, and NC variables.
The R911289021 (PPC-R02.2N-N-L2-NN-NN-FW) is equipped with three axis-processor modules, supplemented by Sercos interface, allowing control of up to 32 drives. Additionally, three optional sockets can accommodate extra axis processors for 8 additional drives. For diagnostic purposes, this device uses a serial COM interface. With its operator input terminal bus, the device is compatible with Rexroth's BTM 15/16 and BTA20 operator terminals. The control unit functions optimally at a temperature range of 0 ᵒC to 45 ᵒC and relative humidity levels between 10% and 95%.
