Product Description:

The BTM03.1-NA-VA-SA-TA-TA-TA-2FF-FW is an operator panel manufactured by Bosch Rexroth Indramat for the BTM03 Machine Operator Panels series. It mounts on machine enclosures and supplies the human-machine interface needed to start, stop, and adjust cutting processes on CNC equipment. Four dedicated module slots let the user combine an emergency-stop function, rotary overrides, and configurable pushbuttons so motion sequences in milling cells can be halted or tuned without accessing the drive cabinet.

The panel face carries an IP65 rating, so dust and low-pressure water jets cannot reach the circuitry even when coolant overspray is present. Slot 1 hosts a locking emergency-off button that stays engaged until deliberately released; its switching element provides two normally closed contacts to comply with dual-channel safety relays. Slot 2 accepts the Feed Override module, giving the operator a rotary switch with 16 detent positions; the engraved scale steps through 0/1/2/4/6/8/10/20/30/40/50/60/70/80/100/120% so feed rates can be reduced or increased in controlled increments during milling operations. The front key module includes 15 LED-equipped keys that illuminate when a function is active, and each key uses a short-stroke mechanism for quick tactile feedback.

The base design assigns Slot 1 to the emergency-stop module and Slot 3 to a spindle override module that mirrors the feed control with its own 16-position detent ring for spindle-speed adjustment, while Slot 4 houses the key module for custom macros. This arrangement lets machine builders map rapid overrides to physical hardware, minimizing search time on graphic screens and improving reaction speed when chips load the tool. By separating safety circuitry from motion scaling and by providing backlit pushbuttons, the panel supports clear status indication and structured operator actions within compact operator stations.
