Product Overview

Efficient motor control is a critical requirement in modern industrial automation, helping manufacturers improve production efficiency, reduce energy consumption, and extend equipment service life. The Schneider ATV12H075M2 is a compact Altivar 12 Frequency Inverter (Variable Frequency Drive, VFD) designed to provide reliable speed control for three-phase asynchronous motors used in industrial machinery and automation equipment.

The inverter converts a fixed single-phase AC input into a variable-frequency three-phase AC output, allowing connected motors to operate at precisely controlled speeds according to process requirements. By adjusting motor speed instead of relying on mechanical control methods, the ATV12H075M2 improves energy efficiency, reduces mechanical wear, minimizes startup current, and enhances overall system performance.

With compact dimensions of 72 × 143 × 131.2 mm and a weight of approximately 0.8 kg, the drive is suitable for compact control cabinets and OEM machinery where installation space is limited. As a member of Schneider Electric’s Altivar 12 family, it combines simple commissioning, dependable operation, and flexible motor control for a wide variety of industrial applications.

Technical Specifications

Function and Working Principle

The Schneider ATV12H075M2 controls the rotational speed of an AC motor by regulating the output frequency and voltage supplied to the motor. Since the speed of an induction motor is proportional to the frequency of the supplied electrical power, changing the output frequency allows the inverter to provide accurate speed regulation while maintaining smooth operation.

Key functions include:

• Variable motor speed control
• Soft starting and stopping
• Adjustable acceleration and deceleration
• Energy-saving operation
• Constant torque performance
• DC injection braking
• Automatic motor protection
• Electronic overload monitoring
• Stall prevention
• Preset speed operation
• Local keypad programming
• External terminal control
• Modbus communication
• Real-time fault diagnostics

The basic operating process is:

AC Power Input → Rectifier → DC Bus → Inverter Circuit → Variable-Frequency AC Output → Motor

The inverter continuously monitors voltage, current, motor temperature, and operating status. When abnormal conditions are detected, integrated protection mechanisms help prevent motor damage and improve equipment reliability.

Role in Industrial Control Systems

Within an industrial automation system, the ATV12H075M2 acts as the intelligent interface between the PLC controller and the electric motor.

Typical automation components include:

• Schneider Modicon PLC
• Schneider Harmony HMI
• Altivar Frequency Inverter
• Motor Circuit Breaker
• Magnetic Contactor
• Three-phase Induction Motor
• Proximity Sensors
• Pressure Sensors
• Emergency Stop Circuit
• Industrial Ethernet Network
• Modbus Communication Network
• SCADA System

The PLC calculates the required motor speed based on production requirements and sends control commands to the inverter. The ATV12H075M2 then adjusts motor frequency and voltage to achieve precise speed regulation.

This intelligent control strategy improves process consistency, minimizes mechanical stress, and significantly reduces energy consumption compared with traditional fixed-speed motor operation.

Industrial Applications

The ATV12H075M2 is suitable for numerous industrial applications requiring compact and reliable motor control.

Typical applications include:
