Product Description:

The BTV20.2CA-64B-10C-D-FW is an operator interface unit produced by Bosch Rexroth Indramat within the BTV20 Machine Operator Panels series. Serving as a combined display and control station, it provides the electrical link between CNC or PLC controllers and machine tool axes. The panel integrates push-buttons, alphanumeric entry, and status LEDs so operators can execute program calls, jog drives, and monitor faults from a single enclosure. Its layout is suited to machine stations where direct visual status and manual input are needed at the same time. By concentrating these functions at the point of use, it reduces cabinet wiring and keeps routine machine interaction in one place.

The front membrane supplies 16 machine function keys that can be assigned to axis enable, cycle start, or coolant commands. Internally, the panel accepts incoming power at AC 115 to 230 V and operates on line frequencies of 50 to 60 Hz, allowing installation in North American and European cabinets without tap changers. The control logic follows the panel function type of MTC within the line 20 architecture. A built-in SDRAM bank provides 64 MB of volatile memory for program variables and CNC buffers, and a standard tactile keyboard handles alphanumeric input. This arrangement supports common machine commands without requiring separate external input hardware.

Primary mass storage is a 3.5-inch disk drive with a formatted capacity of 1.44 MB for part programs, parameter backups, and diagnostic captures. The base system configuration calls for at least 1 GB of nonvolatile storage and a processor clock of 200 MHz, which helps the HMI respond quickly to soft-key events and graphic screen updates. This unit is delivered in design version 2, so its housing dimensions and mounting points match the second mechanical revision of the series. The storage and processor combination supports local file handling while keeping screen response consistent during normal operation.
