Description

• The Schneider Electric Altivar 61 ATV61HD75N4 is a 75 kW (100 HP) variable speed drive from the Altivar 61 series, dedicated to pumping and ventilation machines (fans, pumps, compressors) in industrial and building applications.
  
• Sensorless flux vector control for asynchronous motors and sensorless vector control for synchronous motors, providing high torque and precise speed regulation without feedback devices.

FAQ for ATV61HD75N4

• Q1: What is the difference between Altivar 61 and Altivar 71?

A:The Altivar 61 is optimized for variable torque (quadratic) applications like pumps and fans, while the Altivar 71 is designed for constant torque applications like conveyors, extruders, and hoisting. The ATV61 includes energy-saving algorithms specifically for centrifugal loads.

• Q2: Can the ATV61HD75N4 be used with a synchronous motor?

A: Yes. It supports sensorless vector control for synchronous motors (permanent magnet motors) without a feedback encoder.

• Q3: What is the "Power Removal" function?

A: The Power Removal function (PWR terminal) is a safe torque off (STO) safety function that cuts power to the motor without removing power from the drive's control section.

• Q4: What happens above 50°C operating temperature?

A: Above 50°C, the drive requires derating (reducing output current). Up to 60°C operation is possible with appropriate derating. A control card fan kit is recommended above 50°C for proper cooling.
