The ATV320D15N4B is a variable speed drive from the Altivar Machine ATV320 series, designed for heavy-duty applications in complex machines. It operates on a 380 to 500V three-phase supply, delivering a nominal output current of 33.0 A to control motors up to 15.0 kW. The drive features an integrated Class C3 EMC filter, a built-in brake chopper, and supports both asynchronous and synchronous motor control profiles, including vector control without a sensor. It includes embedded Modbus serial and CANopen communication protocols, along with safety functions such as Safe Torque Off (STO) and Safe Stop 1 (SS1). Its book-style, wall-mount format makes it a versatile solution for industrial automation systems requiring precise motor control.
