Product Description:
The VAM40.2-PB-NA-TA-VB-MA-1608-NN is an HMI unit from the VAM Machine Operator Panels series produced by Bosch Rexroth Indramat. It serves as the local human-machine interface for CNC systems and automated machining centers, giving the operator direct access to feed, spindle, and emergency-stop functions while the controller handles motion and logic tasks. Communication with the control system is handled through the Profibus DP interface, allowing cyclic process data and diagnostic bits to be transferred without hardwired interlocks.
This panel provides 16 digital inputs for status signals or sensor contacts and 8 digital outputs for driving lamps or relays. All I/O channels share a galvanically isolated 24 V DC supply that can deliver up to 1.7 A to external loads. The internal logic electronics draw 0.5 A from the same supply rail used by the I/O block. Dedicated rotary selectors provide 16 feed-override steps and 16 spindle-override steps, allowing the operator to adjust velocities in fixed increments instead of entering numerical values. Contact debouncing helps the PLC interpret changes from the panel controls reliably. The available output capacity supports auxiliary lamps and contactors without requiring an additional supply module for those loads.
The sealed front foil has an IP54 rating, protecting the internal circuitry against dust and splashed coolant during normal machine operation. The panel measures 407 × 169 × 58 mm, while cabinet preparation requires a 379 × 141 mm cutout. Installation also requires a mounting depth of 102 mm behind the cabinet surface so the enclosure and connections have sufficient clearance. The emergency-stop channel supports currents up to 0.5 A, which is suitable for typical safety-relay sensing circuits. The tactile key switch provides four-position mode selection and is rated for 50,000 cycles. Its fixed positions allow operating modes to be selected directly from the panel while helping prevent unintended changes during machine use.
