Product Description:

The VAM81.1-USB-NF-TA-TA-VE-MA-NNNN operator terminal is produced by Bosch Rexroth Indramat as part of the VAM Machine Operator Panels series. The unit is a handheld interface used to initiate motion sequences, issue override commands, and perform machine setup tasks in industrial automation cells. It is intended for use with Rexroth IndraDrive or CNC platforms, and its handheld format supports local operation at the machine.

It receives control power from a 24 V DC supply and draws a nominal current of 0.3 A, allowing the panel to be powered directly from standard control cabinets. Incoming voltage enters through a 2-pin power connector, and a parallel circuit routes to a stop circuit that terminates on four dedicated stop-switch pins. The operator surface carries 32 programmable membrane keys that transmit discrete commands to the controller. For data exchange and service access, the housing provides a USB1A interface; the associated link uses a shielded cable with a maximum length of 1.0 m and four USB signal pins to maintain signal integrity inside moving cable chains. These values set the power and wiring limits for the panel.

Additional field signals can be connected through 16 extended inputs and 8 extended outputs, giving room to map auxiliary sensors, pilot lights, or interlocks without external junction boxes. A precision handwheel is supported through a 25-pin D-SUB connector, and its position channel accepts a differential quadrature signal while the step output to downstream drives uses an open-collector stage that simplifies wiring to opto-isolated counters. The product also includes a 4-pin auxiliary handwheel socket, four labeling strips for custom key legends, and an M5 mounting nut that locks the enclosure to machine brackets during production. The panel can handle local jog control, status indication, and incremental feedback in a compact housing.
