This NCU 6FC5357-0BB33-0AA1 and SIEMENS module is a digital control unit of the SINUMERIK 840D range.
SINUMERIK 840D/DE NCU 573.3, 650 MHZ, 64 MB WITHOUT SOFTWARE SYSTEM MEMORY: NC 2.5 MB, AP 96 KB PREPARED FOR PROFIBUS DP
This NCU 6FC5357-0BB33-0AA1 SIEMENS is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
The components of the SINUMERIK 840D are compatible with the module se- ries SIMODRIVE 611D. The 840D is operated with the power supply of SIMODRIVE 611 and the SIMODRIVE 611D drive modules.
The NCU module (Numeric Control Unit) is the CPU of the SINUMERIK 840D. It takes over all the CNC, PLC and communication tasks
The NCU box is the module rack of the NCU module and consists of:
- NC rack assembly with cable distributor
- Battery/fan slide-in module
- Sheet metal housing with integrated guide bars for accommodating the NCU and the fan/battery slide-in modules and power supply unit.
The fan box is absolutely required for the 573.3 (Pentium III) and 573.4 (Pen- tium III) NCUs. Mount the fan box to the NCU box if necessary.
As a submodule of the NCU, the PLC module supports machine monitoring and represents a PLC-CPU that is compatible to the S7-300 family of products. Via the P bus, three external lines can be connected for every eight S7-300 periph- eral modules.
The COM module is a submodule of the NCU. It is used for communication with the PCU and peripherals.
The driver module is a submodule of the NCU (...-...-0AEx). It forms the inter- face to the operator panel front, to the programming device, to the decentralized peripherals and to S7-300 peripherals.
The NCU contains a plug-in unit for standard PCMCIA cards (PC card or NC card), via which all flash cards of type II up to 8 MB storage capacity can be operated.
The PCMCIA card serves as a bulk memory for the NC system software (NC card).
