Features:
- upports sensorless flux vector control (SFVC) for asynchronous motors and synchronous permanent magnet motors.
- Features Safe Torque Off (STO) conforming to ISO 13849-1 level d with ≤100ms response time.
- Provides 2 analog inputs (bipolar ±10V and configurable 0-20mA/0-10V), 1 analog output, 7 discrete inputs (including PTC probe and safety input), and 2 relay outputs (5A rating).
The ATV71HD18N4 is engineered for applications requiring precise motor control, such as conveyors, hoists, and extruders. It offers sensorless flux vector control (SFVC) for asynchronous motors, delivering high torque accuracy (±15%) and speed regulation (±10% of slip) without an encoder, simplifying installation and reducing costs. For maximum precision, flux vector control (FVC) with encoder feedback provides ±0.01% speed accuracy and ±5% torque accuracy, with a speed range of 1:1000. The drive also supports synchronous permanent magnet motors, enabling energy-efficient operation.
The ATV71HD18N4 simplifies system design with built-in safety and communication functions. The Safe Torque Off (STO) function, conforming to ISO 13849-1 level d, provides a hardware-based safety path that prevents unexpected motor start, critical for maintenance safety. Response time is ≤100 ms from safety input to output removal. The drive can be integrated with Preventa XPS AC or XPS ATE safety modules for applications requiring category 3 or SIL2 per IEC/EN 61508, with wiring diagrams provided for emergency stop (category 0) and controlled stop (category 1) configurations.
The ATV71HD18N4 provides extensive I/O for flexible system integration without additional modules. Two analog inputs are available: AI1 accepts bipolar differential voltage (±10V) with 11-bit plus sign resolution, while AI2 is software-configurable for current (0-20mA, 242Ω impedance) or voltage (0-10V, 30kΩ impedance) with 11-bit resolution. One analog output (AO1) is software-configurable for current (0-20mA) or voltage (0-10V) with 10-bit resolution. Seven discrete inputs include LI1-LI5 (24V DC, programmable), LI6 (configurable as logic input or PTC probe), and PWR safety input for STO function.
The ATV71HD18N4 SCHNEIDER Variable Speed Drive may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).
