is a Schneider Electric Altivar Machine ATV340 variable speed drive (VFD) designed for high-performance machine applications. It is an IoT-ready solution specifically engineered for harsh environments, supporting both synchronous and asynchronous motors with a rated power of 0.75 kW (1 HP) for heavy-duty use.
Key Specifications
Power Rating: 0.75 kW (1 HP) for heavy-duty; can reach 1.1 kW (1.5 HP) for normal-duty applications.
Voltage: 3-phase, 380V to 480V AC.
Current Rating: 2.2 A (Heavy Duty) and 2.8 A (Normal Duty).
Communication: Integrated Modbus serial line as standard. Note that the "E" at the end of some models (like ATV340U07N4E) indicates embedded multi-protocol Ethernet, which this specific model does not have by default.
Environmental Resistance: Designed for high-temperature resistance up to 60C and resistance to vibration, shock, and non-conductive dust.
Protection Rating: IP20.
Dimensions: 85 mm (W) x 270 mm (H) x 232.5 mm (D); Weight: 1.7 kg.
is a high-performance variable speed drive (VFD) primarily used for precise motor control and machine automation. It functions as the "brain" for 3-phase asynchronous and synchronous motors, providing advanced speed and torque regulation.
Core Functions & Capabilities
Motor Control: Supports both open and closed loop control. It handles multiple motor profiles including constant torque standard, variable torque standard, optimized torque mode, and support for permanent magnet and reluctance motors.
Safety Features: Includes critical integrated safety functions like Safe Torque Off (STO), Safe Stop 1 (SS1), and Safely Limited Speed (SLS) to protect personnel and machinery.
Dynamic Performance: Capable of 4-quadrant operation and high dynamism, providing up to 220% nominal torque for 2 seconds to handle demanding machine starts.
Connectivity & Diagnostics: Features an integrated Modbus serial port as standard for communication. It is fully compatible with Schneider's EcoStruxure Machine and can be configured/diagnosed via SoMove or SoMachine software.
Process Regulation: Includes an adjustable PID regulator for maintaining setpoints in applications like pressure or flow contro.
Input/Output Interface
Digital I/O: 5 discrete inputs (including pulse input up to 30 kHz) and 2 programmable digital outputs.
Analog I/O: 2 analog inputs (software-configurable for voltage, current, or temperature probes) and 1 analog output.
Relays: 2 relay outputs (R1 and R2) for status signaling and fault detection.
Operational Versatility
Preset Speeds: Allows for up to 16 preset speeds.
Braking: Includes an integrated brake chopper and supports braking to a standstill via DC injection.
Environment: Built for harsh conditions, resisting non-conductive dust, vibration, and high temperatures up to 60C.
