ATV320U22N4B

Schneider Electric ATV320U22N4B is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar Machine 320 series, designed for cabinet mounting with a built-in EMC filter and ATEX compliance. It operates with a supply voltage of 323-550Vac, supporting 380Vac, 400Vac, 480Vac, and 500Vac nominal values. The device dimensions are H325mm x W60mm x D245mm, featuring an IP20 degree of protection. It has a rated current of 5.5A at 4kHz and can handle a maximum current of 8.3A for up to 60 seconds. The ATV320U22N4B supports a 3-phase network with an output frequency range of 1-599 Hz. It includes 1 analog output (0-10Vdc / 0-20mA), 4 digital inputs (24Vdc; sink/source), an additional programmable digital input, and a digital input for Safe Torque Off (STO). The device also features 1 digital output (24Vdc; sink/source), 1 changeover SPDT relay contact, and 1 normally open relay contact, alongside 2 analog inputs (-10...+10Vdc) and 1 analog input (0-20mA / 4-20mA). It has a current consumption of 8.7A at 380Vac and 6.6A at 500Vac, with a rated active power of 2.2kW (3HP) and power dissipation/losses of 78 W. Communication is facilitated via Modbus and CANopen protocols. The drive incorporates advanced functions such as STO, SS1, SLS, SMS, GDL, U/F ratio adjustments, sensorless flux vector control, and customizable application functions with ATV Logic, supporting both velocity mode and torque control operations.
