Product Overview

The Schneider Electric ATV71HC16N4 functions as a high-performance frequency inverter within the Altivar 71 family. This variable speed drive (VSD) manages three-phase asynchronous motors with a power rating of 160 kW (notably higher than smaller frame sizes) across a voltage range of 380V to 480V. By employing advanced vector control algorithms, the ATV71HC16N4 delivers exceptional torque and speed precision, making it indispensable for high-torque industrial applications such as hoisting, constant-torque conveyors, and complex process machinery.

Core Functional Capabilities

  • Optimizes Dynamic Motor Control: The drive utilizes sophisticated control laws to maintain full torque at zero speed. This capability ensures smooth startups for heavy loads and precise speed regulation during fluctuating process demands.
  • Ensures Functional Safety: Integrated safety functions, including “Safe Torque Off” (STO), comply with IEC/EN 61508 SIL2 standards. Consequently, the drive protects personnel and equipment by preventing accidental motor restarts during maintenance.
  • Facilitates Advanced Communication: The unit features built-in Modbus and CANopen protocols. It also accepts various optional communication cards (Ethernet/IP, Profibus DP, DeviceNet), allowing seamless integration into distributed control architectures.
  • Protects Power Quality: The design accommodates external DC chokes or line chokes to suppress harmonic distortion. This feature stabilizes the electrical network and extends the operational life of sensitive downstream electronics.
  • Simplifies Diagnostics and Monitoring: An integrated graphic display terminal provides real-time status updates and fault signaling via dedicated relay contacts. These tools allow operators to identify and resolve performance issues before they lead to unplanned downtime.
