The 3AXD50000716364: The module carries 4 digital inputs and 2 digital outputs, plus 2 analog inputs and 1 analog output, which covers basic speed reference and run/stop control without an extra I/O slice. Communication is handled via MODBUS RTU on the built-in serial port — no Ethernet on this frame, so if the line calls for PROFINET or EtherNet/IP, this isn't the slice.
Above 2000 m, the installer needs to apply the standard IEC/UL altitude derating curve; the drive itself doesn't carry a higher rating.
