Product Description:

The BTM04.1-NA-TA-TA-VA-2EF-FW is a machine operator panel produced by Bosch Rexroth Indramat for the BTM04 Machine Operator Panels series. Installed on machining centers, the panel serves as a fixed human-machine interface for feed override selection, emergency stop signaling, and direct key input to a connected CNC or PLC. By combining these manual controls in one compact front assembly, it reduces the need for separate operator hardware and keeps commonly used functions within easy reach during machine operation.

An emergency stop pushbutton with a locking action is integrated so the button remains engaged until it is deliberately reset, and 2 N/C contacts relay the stop command through dual safety channels. Feed rate adjustment is handled through a rotary selector with 16 distinct override positions, allowing finer speed changes than a simple high or low setting. Three feed-override switch keys provide quick toggling between preset spindle or axis feed settings when operating conditions change. The override hardware is optimized for milling tasks, so the operator can slow the tool during tight contours and return it to a higher feed level when the cut path becomes less demanding. Key legends on the panel are writable, which allows each function to be labeled clearly for the machine on which the panel is installed.

The tactile section uses short-stroke key switches that provide clear feedback while keeping travel distance low for faster actuation. Two keyboard modules are mounted side by side, and each module contains 15 keys. This gives the panel a total of 30 direct-input keys for cycle commands and auxiliary machine functions. The side-by-side arrangement helps separate frequently used controls from secondary inputs, and the modular keyboard design supports user-applied overlays that keep the writable legends visible in oil mist or coolant-rich environments.
