Features:
- Altivar 61 variable speed drive (VSD)
- SPEED DRIVE,100HP,460V,ATV61
- It is specifically engineered for variable torque applications
Primarily used for precise control of the speed and torque of three-phase asynchronous motors. Its core function lies in smoothly regulating the speed of fans, pumps, and general mechanical loads by adjusting the output frequency and voltage, thereby significantly improving system energy efficiency and reducing mechanical shock. This device integrates various industrial application macros to adapt to control requirements under different operating conditions and supports dynamic response optimization in complex process control.
Functionally, the ATV61HD75N4 provides comprehensive motor protection and system diagnostics, including overload protection, overheat monitoring, undervoltage and overvoltage protection mechanisms, as well as operational status monitoring and fault logging functions. These features enable it to maintain stability and reliability in high-load, continuous-operation industrial environments.
The ATV61HD75N4 Schneider Electric Altivar 61 variable speed drive may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

In terms of operating principle, the ATV61HD75N4 adopts a rectifier-DC bus-inverter frequency converter drive architecture. First, the input three-phase AC power is converted into DC voltage by the rectifier module, and then output to the DC bus after filtering and voltage regulation. Subsequently, the inverter unit utilizes power semiconductor devices such as IGBTs to generate AC outputs with variable frequency and variable voltage through pulse width modulation (PWM) technology. The control system acquires motor feedback signals in real time and dynamically adjusts the PWM waveform through vector control or V/F control algorithms, thereby achieving precise adjustment of the motor's magnetic field and torque, and ultimately realizing efficient and stable speed control.
This drive is designed for industries where precise control of pumps and fans is critical to ensure performance and energy efficiency.
Pumping Machinery: Widely used in water management and wastewater treatment for regulating the flow rate of centrifugal pumps.
