Schneider Electric's ATV31H075N4 is a variable speed drive tailored for enhancing motor control in a variety of settings. This drive is rated to work with input voltages ranging from 380 V to 500 V AC, with a tolerance of ±5%. It operates within a frequency range of 47.5 to 63 Hz, accommodating different system requirements. Its motor power handling capability is rated at 0.75 kW (or 1 HP) at a switching frequency of 4 kHz, and it can maintain an output current of 2.3 A effectively under these conditions. In scenarios demanding higher current, it can handle peak transient currents of up to 3.5 A for up to 60 seconds.
The control scheme employed is sensorless flux vector PWM, which facilitates precise control of motor operations. To meet stringent electromagnetic compliance standards, it comes with an integrated EMC filter. For application flexibility, the switching frequency of the drive can be adjusted within a range of 2 to 16 kHz. Furthermore, the dynamic braking feature can provide torque up to 150% of the motor’s rating when coupled with an external resistor for a duration of 60 seconds.
This drive supports multiple communication interfaces, including CANopen and Modbus, accessible via RS485 connections using RJ45 ports. Operational temperatures are broad, spanning from -10°C to +50°C without derating when a protective cover is used. The enclosure offers IP20 protection for the top section and IP21 for the terminal block, safeguarding internal components from dust and water.
To ensure reliable operation, the ATV31H075N4 incorporates various motor protection safeguards, including thermal overload, phase loss, and short-circuit protections. Additionally, it includes three analog signal inputs, which can be configured for 0–20 mA or ±10 V signals, allowing for adaptable integration into existing systems.
