What it is and where it sits
The ABB ACS355-01E-04A7-2 is a member of the ACS355 machinery-drive family, sized as a module for cabinet building on a single-phase 200 … 240 V supply at 50/60 Hz. The model code places it in the lower-power, single-phase end of the ACS355 range, intended for compact panels driving small three-phase motors where only a 1-phase mains feed is available. It builds out at R1 frame size, occupying a 70 mm wide × 239 mm tall × 161 mm deep footprint at 1.8 kg. Open Type / IP20 construction keeps it as a panel-internal module — no field mounting, no washdown duty. Shipping weight is 3 kg, which is the handling number for the carton, not the panel-load number.
What the ratings actually decide
The 200 … 240 V single-phase input is the figure that governs. Line side takes L+N; motor side still runs a three-phase motor from the drive's switched output. The I/O budget — 5 digital inputs, 1 digital output, 2 analog inputs, 1 analog output — is the parameter the controls engineer commits to first. With MODBUS as the only listed fieldbus, any PLC tag map rides that single protocol; there is no PROFINET or EtherNet/IP inside this code, so plan the comms drop accordingly.
