Effective motor control is the foundation of all current industrial automation processes. Performance, energy costs, and equipment life are all directly impacted by the way motors start, stop, and operate in everything from pumping stations and HVAC systems to conveyors and crushers.
This process is optimized with Altivar (ATV) variable frequency drives and Altistart (ATS) soft starters, two of Schneider Electric’s most dependable motor control technologies. Many customers, however, are unsure about which option, ATS or ATV, to select.
In order to help you choose the best system for your applications, Al Barq KSA, an authorized Schneider Electric partner in Saudi Arabia, is available to assist you in comprehending the main distinctions, applications, and advantages of each system.
Understanding the Basics: ATV vs. ATS
Both ATV (Altivar) and ATS (Altistart) are designed to control electric motors, but they do so in very different ways.
- ATV (Altivar) refers to Variable Frequency Drives (VFDs). These devices control motor speed and torque by adjusting the frequency and voltage supplied to the motor.
- ATS (Altistart) refers to Soft Starters, which control the voltage only during motor startup and stopping, providing a smooth acceleration and deceleration without constant speed control.
Simply put, if your process requires speed variation and continuous control, the ATV series is the right choice. If you only need a gentle start and stop, the ATS series is more suitable.
When to Choose the ATV Series (Variable Frequency Drives)
The Altivar (ATV) drives, such as the ATV310, ATV610, ATV630, and ATV930, are powerful solutions for applications that need precise motor control, energy efficiency, and process optimization.
Here’s why and when you should choose a VFD like the ATV:
- Speed Control & Process Flexibility
A motor can be operated at multiple speeds with VFDs to accommodate changing loads or process needs. Energy can be saved, for instance, in water pumps or HVAC systems, where the flow rate can be accurately controlled without mechanical throttling. - Energy Efficiency
Motors frequently operate below their maximum capacity, so lowering speed results in lower energy usage. There are significant long-term savings as a result. - Smooth Starting and Stopping
ATV drives minimize wear on gears, belts, and couplings by providing smooth acceleration and deceleration, much like soft starts. - Advanced Monitoring & Integration
The ATV series supports smart connectivity via Modbus, Ethernet/IP, and EcoStruxure, making it ideal for Industry 4.0 environments where real-time monitoring and control are essential.
5. Applications
Pumps, fans, conveyors, mixers, compressors, and HVAC systems.
In short, choose the ATV series when speed control, energy savings, and automation are critical to your process.
When to Choose the ATS Series (Soft Starters)
The Altistart (ATS) range, including ATS22, ATS430, and ATS480, provides a simpler, more cost-effective way to start and stop motors smoothly.
Here’s why and when the ATS might be your best fit:
- Gentle Motor Acceleration
During startup, the ATS prevents excessive stress on motors and related equipment by limiting inrush current and mechanical shock. - Reduced System Costs
Because it doesn’t require speed control components, the ATS is simpler and more affordable than a VFD. - Compact Design & Easy Setup
Soft starters are easier to put in panels with limited space because they are smaller. - Reliability in Heavy-Duty Applications
The most recent ATS models, such the ATS480, have integrated communication features and strong protection, making them ideal for harsh industrial settings.
5. Applications
Pumps, compressors, conveyors, crushers, and heavy machinery that only operate at full speed.
In short, choose the ATS series when you need smooth, reliable starts and stops but not continuous speed regulation.
