ATV340D11N4E

Schneider Electric

Schneider Electric ATV340D11N4E is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar Machine 340 series. It features Safe Torque Off up to SIL3 / PLe with dual input, 5 points U/F, sensorless voltage vector control, current vector control with sensor, and Master/Slave daisy chain through PTO/PTI for MachineStruxure integration in SoMachine. It operates in velocity mode and torque control, offering 220% Tn in open or closed loop control, dynamic motor control performance (up to 400Hz speed bandwidth), and cyclic application task (1ms) with an energy-saving mode. The design includes a built-in EMC filter (class C3) and a built-in heatsink. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nom.), with dimensions of H385mm x W180mm x D249mm and an IP20 degree of protection. The rated current is 32A (normal-duty; 4kHz), 24A (heavy-duty; 4kHz), with a maximum current of 43A (normal-duty; for 2s), 43A (heavy-duty; for 2s), and 35.2A (normal-duty; for 60s), 36A (heavy-duty; for 60s). It supports cabinet mounting, Ethernet/IP, Modbus TCP communication protocols, operates on a 3-phase network with an output frequency of 1-599 Hz, and includes 1 x analog output, 5 x digital inputs, 2 x digital outputs programmable as inputs or outputs, 1 x digital output (C/O SPDT relay contact), 1 x digital output (NO relay contact), and 2 x analog inputs. The current consumption is 34A (380Vac; normal-duty), 27.3A (480Vac; normal-duty), 34.7A (380Vac; heavy-duty), 27.7A (480Vac; heavy-duty), with a rated active power of 15kW (normal-duty), 11kW (heavy-duty), and rated power of 20HP (normal-duty), 15HP (heavy-duty).
