Product Overview

The Schneider Electric ATV320U15S6C Variable Speed Drive is an Altivar Machine ATV320 frequency inverter designed to provide adjustable speed and torque control for three-phase AC motors used in industrial machinery, OEM equipment, and automated production systems.

This model is designed for a 200–240 V AC three-phase power supply and provides a 1.5 kW (2 HP) motor power rating. It converts incoming electrical power into a controlled variable-frequency three-phase output, allowing the connected motor to operate at different speeds according to machine requirements.

The ATV320U15S6C uses a compact enclosure measuring approximately 105 × 142 × 158 mm, with a specified weight of approximately 1.29 kg. Its compact physical design allows it to be integrated into machine control panels and industrial cabinets where installation space is limited.

The drive is intended for applications requiring controlled motor acceleration, deceleration, speed regulation, torque management, motor protection, communication, and machine safety functions.

Typical applications include conveyors, packaging machinery, material-handling systems, feeders, pumps, fans, textile machinery, mechanical equipment, and OEM automation systems.

Technical Specifications

Function and Working Principle

The main function of the ATV320U15S6C is to regulate the speed and torque of a compatible three-phase AC motor.

The drive receives three-phase AC power and converts it into a controlled electrical output for the motor.

The basic power-conversion process can be represented as:

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

The incoming AC power is first converted into DC power through the rectifier section. The DC link provides an intermediate energy stage before the inverter section converts the DC voltage back into a controlled three-phase output.

By adjusting output frequency and voltage, the drive can regulate motor speed. The control system also monitors electrical operating conditions such as current and drive status.

The ATV320U15S6C can therefore support:

• Variable motor speed
• Controlled acceleration
• Controlled deceleration
• Soft starting
• Controlled stopping
• Torque management
• Motor current monitoring
• Motor overload protection
• Braking functions
• Fault detection
• Warning monitoring
• Speed reference control
• PLC-based motor control

Vector-control capability can provide improved motor performance compared with basic scalar control in suitable applications.

The actual control configuration should be selected according to the motor type, machine load, required speed range, starting torque, and application requirements.

Role in Industrial Control Systems

The ATV320U15S6C normally functions as the motor-control device between the electrical supply and a machine’s three-phase motor.

A typical industrial control architecture is:

PLC / Controller → ATV320U15S6C → Three-Phase AC Motor → Mechanical Load

The PLC handles machine sequencing, logic, sensor signals, production commands, and process coordination.

The drive receives the required speed or operating command and converts it into an appropriate motor output.

For example, a PLC may command the drive to operate the motor at a particular speed during one stage of a production cycle. When the process changes, the PLC can issue another reference and the drive adjusts the motor accordingly.

The drive can also provide operational information to the control system.

Typical information includes:

• Drive status
• Motor frequency
• Motor current
• Speed reference
• Warning status
• Fault status
• Operating state
• Diagnostic information

This allows the drive to operate as part of an integrated automation system rather than as an isolated motor controller.

In machines containing several motors, multiple ATV320 drives can be coordinated through a PLC or industrial communication network.

Industrial Applications
