I/O and communication — what is on board
The 3AXD50000035909: The drive includes a control unit with 2 analog inputs, 2 analog outputs, 6 digital inputs, and 2 digital outputs. Communication is CAN-based; there are no onboard industrial Ethernet interfaces (0 hardware interfaces for Ethernet). For fieldbus integration, an optional adapter module would be needed — the base unit does not carry PROFINET, EtherNet/IP, or Modbus TCP on the standard control board. A lithium coin cell (CR2032, 220 mAh, 3 V, two pieces) backs up the real-time clock and parameter storage. The battery is a consumable; factor replacement into long-term maintenance schedules — typical life is several years, but the drive will flag a low-battery warning before data loss.
