Ratings that matter for cold-chain and pump loads
The 3AXD50000034622: The heavy-duty current rating of 45 A is the number to size by if you're driving a refrigeration compressor or a variable-torque pump that sees occasional overloads. Normal-use 62 A covers constant-torque loads like fans or conveyors in a cold-store environment. Ambient temperature maxes out at 50 °C, which gives headroom even in a warm mechanical room. Altitude rating of 4000 m means no derating needed for most installations — only high-altitude plants above that need a check. The IP55 and NEMA Type 12 enclosure keeps out dust and hose-directed water, so it's at home on a wall near a washdown station or in a humid wastewater plant.
Onboard communication is CAN; there are zero Industrial Ethernet interfaces on this variant. If you need Modbus TCP, PROFINET, or EtherNet/IP, you'll add an option module. The drive carries 6 digital inputs and 3 digital outputs, plus 2 analog inputs and 2 analog outputs — enough for basic pump control with feedback from a pressure transmitter.
