Physical & environmental constraints
The 3AXD50000145966: Frame size is 4xR8i+4xR8i — that is eight R8i modules in a four-plus-four parallel arrangement. The enclosure is NEMA 1 (IP22), so it is drip-proof but not dust-tight; mount it indoors, away from washdown areas. Ambient temperature tops out at 40 °C, with derating above that. Altitude rating is 1000 m without derating. Sound level hits 79 dB(A) at full load — plan for hearing protection if the drive is on the plant floor near operators.
Control & I/O
The control unit is included. It provides 4 analog inputs, 4 analog outputs, and 14 digital I/O plus 10 digital outputs. Communication is CAN-based; there is no onboard industrial Ethernet port, so a fieldbus adapter module will be needed for PROFINET or EtherNet/IP integration. The onboard real-time clock runs on two BR2032 lithium coin cells — expect to replace them during the drive's service life, not at commissioning.
