Typical Applications for the 37 kW ATV930
Schneider Electric lists the ATV930D37N4 for applications in:
- Food and beverage: mixers, conveyors and shredders
- Oil and gas: progressive cavity pumps, rod pumps, compressors, separators and drilling rigs
- Material working: presses and extruders for wood, ceramic, stone, PVC and metal
- Marine and hoisting: thrusters, winches and process cranes
- Mining, metals, water and wastewater: separators and other process duties
Connectivity: EtherNet/IP, Modbus TCP and Modbus Serial
The control block has two RJ45 ports for EtherNet/IP and Modbus TCP (10/100 Mbit/s) and one RJ45 port for Modbus serial over 2-wire RS-485. For other networks, Slot A takes PROFINET, PROFIBUS DP V1, EtherCAT, DeviceNet or CANopen modules (RJ45 daisy chain, SUB-D 9 or screw terminals).
Control Inputs, Outputs and Expansion Slots
- Digital inputs: 8 programmable (DI1–DI8), with DI7 and DI8 also usable as 30 kHz pulse inputs
- Safety inputs: 2 Safe Torque Off inputs, SIL 3 rated
- Analog inputs: 3 (AI1–AI3), 0–10 V or 0/4–20 mA, 12-bit resolution
- Analog outputs: 2 (AQ1, AQ2), 0–10 V or 0–20 mA, 10-bit resolution
- Logic outputs: 2, with DQ+ programmable as a pulse output
- Relays: 3 (R1 fault relay NO/NC; R2 and R3 sequence relays NO)
- Expansion: I/O and relay extension modules in Slots A, B and C; digital, analog or resolver encoder interfaces in Slot B
Motor Control Modes and Built-in Protection
The drive provides constant torque, variable torque and optimised torque profiles for asynchronous motors, plus a dedicated permanent magnet motor law. Other functions include 16 preset speeds, adjustable slip compensation, DC injection braking and separate linear ramps from 0.01 to 9999 s. Built-in protections cover overheating, overcurrent, short circuit, DC bus overvoltage, line supply phase loss and under/overvoltage, motor phase break and overspeed.
