Product Description:

The BTM03.1-NA-TA-TA-TA-VA-BA-2FF-FW belongs to the BTM03 Machine Operator Panels series produced by Bosch Rexroth Indramat. This unit is a front-mounted interface used on CNC and automation systems to let the operator trigger an emergency stop, adjust feed rates, and enter commands without accessing the drive cabinet. By combining emergency-stop circuits, feed-override hardware, and keyboard modules in one enclosure, the panel simplifies control-station wiring and reduces interruption time when service is required.

Safety control is handled by a single emergency-stop module that routes motion-inhibit signals through 2 N/C contacts and is actuated with a locking emergency-off key, so the stop position cannot be cleared without an intentional reset. Feed regulation is managed by one override module, and its rotary switch uses an LED ring and can latch into 17 discrete detents. The selected detent maps directly to an override scale of 0, 1, 2, 3, 4, 6, 8, 10, 20, 30, 40, 50, 60, 70, 80, 100, and 120%, allowing the PLC to read a predictable percentage instead of an analog continuum. This hardware approach removes conversion error and supports repeatable feed reductions during threading, drilling, or contour milling.

The panel uses 1 emergency-stop module, which meets basic category-0 stop requirements for single-station machines. The override switch is fitted with 3 dedicated keys, preventing accidental displacement of the knob once a feed limit is chosen. Keyboard entry relies on three plug-in keypad sections built with a writable surface so function legends can be adapted to each application. For machining centers, the override profile is set for milling, so the detent map matches the typical spindle-to-axis feed ratio used in ISO G-code programs. One blank module is included to reserve space for future buttons or indicators when the machine layout changes.
