Product Description:

The BTM04.1-NB-TA-TA-VA-2EF-FW operator panel is produced by Bosch Rexroth Indramat and belongs to the BTM04 Machine Operator Panels series. It serves as the local human-machine interface on CNC or PLC stations, giving the machine operator direct push-button and membrane keypad access to feed, spindle, and safety functions. By integrating multiple input modules and status indicators in one enclosure, the panel simplifies field wiring and reduces cabinet space.

It requires a control supply of 24 VDC, so all switches and LEDs operate at the standard logic level present in most Indramat automation racks. Machine signals reach the panel through the local input connectors X28/X29, which accept pre-assembled wiring harnesses to speed installation. The keypad area is organized in 2 keypad modules, and together they provide tactile access to 30 keys that can be assigned to axis jog, program start, or custom macros. Safety integration is handled by the dedicated Slot 1 module, a red-mushroom Emergency Stop that opens the control circuit immediately when pressed, fulfilling the stop category 0 requirement.

Process adjustment functions are grouped in the Slot 4 assembly for rapid operator input during active machine cycles. Its feed-override hardware presents 3 PB / 3 LEDs, giving stepped percentage selection with corresponding visual feedback. These signals reach the control system through the Slot interface connector X8, which provides a shielded multipole link back to the drive controller for reliable signal transfer. The Slot 4 logic implements the Feed Override feature without external relays, and every keypad section carries its own indicator matrix totaling 30 LEDs to mirror machine states, alarm codes, or soft-key assignments. The layout keeps status information visible while keeping wiring complexity low.
