Technical Specifications

Function and Working Principle

The primary function of the ATV320U15M2B is to provide adjustable speed and torque control for a compatible three-phase AC motor.

The drive receives 200–240 V single-phase AC power and converts it into a controlled three-phase output for the motor.

The basic conversion process is:

Single-Phase AC Input → Rectifier → DC Link → Inverter → Variable-Frequency Three-Phase Output → Motor

The incoming AC voltage is rectified into DC power. The DC link provides an intermediate energy stage, while the inverter uses semiconductor switching to generate a controlled three-phase waveform.

By changing the output frequency and voltage, the drive can regulate motor speed. The drive also monitors motor current and operating conditions to maintain appropriate motor performance and protection.

The ATV320U15M2B can therefore provide:

• Adjustable motor speed
• Controlled acceleration
• Controlled deceleration
• Soft starting
• Controlled stopping
• Torque management
• Low-speed operation
• Motor current monitoring
• Motor overload protection
• Dynamic braking
• Fault detection
• Warning monitoring
• Speed reference control
• PLC-based motor control

The ATV320 family supports sensorless flux vector control, which can provide improved torque performance and speed regulation compared with basic V/F control in appropriate applications.

This makes the drive suitable for machines where stable motor operation is required across different operating speeds and load conditions.

Role in Industrial Control Systems

The ATV320U15M2B normally acts as the motor-control interface between the electrical power supply and the machine’s three-phase motor.

A typical control architecture is:

PLC / Controller → ATV320U15M2B → Three-Phase AC Motor → Mechanical Load

The PLC manages machine logic, sequencing, sensors, interlocks, and production requirements, while the ATV320U15M2B controls the motor’s electrical operating conditions.

For example, a PLC may send a speed reference to the drive based on production requirements. The ATV320U15M2B processes this command and adjusts the motor output accordingly.

The drive can also transmit operating information back to the controller.

Typical feedback information includes:

• Motor frequency
• Motor current
• Speed reference
• Drive operating status
• Warning status
• Fault status
• Motor-control information
• Diagnostic information

This allows the drive to become part of an integrated machine-control architecture.

When multiple motors are used in a production machine, individual ATV320 drives can be controlled by the same PLC or industrial network. This allows different motors to operate at different speeds while remaining synchronized with the overall machine process.

Industrial Applications
