SELECTION COMPARISON
Overview
ATV320 and ATV630 both belong to Schneider Altivar series drives, but their application focus is completely different.
ATV320 is oriented to mechanical equipment manufacturing (OEM), emphasizing compact structure and dynamic response; ATV630 is oriented to process industries, emphasizing energy efficiency and process control of pumps and fans.
The common consequences of wrong selection are: using ATV630 to drive highly dynamic mechanical equipment, resulting in insufficient response; or using ATV320 as a high-power pumping station, lacking process control functions and insufficient power range.

| Comparison point | ATV320 (Altivar Machine) | ATV630 (Altivar Process) |
|---|---|---|
| positioning | Machinery/OEM | Process Industries / Pumps and Fans |
| typical loads | Packaging, handling, textile, woodworking machinery | Water pumps, fans, compressors |
| construction | Compact and Book | Wall-mounted, IP21/IP54 |
| power range | primarily lower power ratings | extends to higher power ratings |
| safety functions | integrated STO | select by configuration |
| control focus | Dynamic response, positioning control | Energy efficiency optimization, process regulation |
| key selection criteria | Load inertia, acceleration and deceleration requirements, installation space | Flow head curve, energy consumption, degree of protection |
How to Decide
- Whether the load is mechanical transmission or fluid transportation - choose ATV320 for machinery and ATV630 for pump and fan.
- Whether you need frequent starts and stops and rapid acceleration and deceleration - if so, lean towards ATV320.
- Installation environment protection requirements - For site dusty and humid environments, the IP54 configuration of ATV630 will be given priority.
- Do you need deep linkage with the process control system? If so, choose ATV630.
- Power requirements - high-power pump station applications directly enter the ATV630 or ATV930 selection.
Common Pitfalls
Think of "same power" as "interchangeable".
The control algorithm, parameter structure and wiring definition of the two are different, and they need to be re-debugged when replacing them.
Choosing the ATV320 for a pump application based on price alone resulted in a lack of energy saving and process features and higher long-term operating costs.
Ignore the structural differences: The installation dimensions of the ATV320 Compact and Book types are different, and the cabinet space needs to be confirmed in advance.
Frequently Asked Questions
Can the ATV320 be used in water pumps?
Pump applications with low power and simple control requirements can be used, but they lack the dedicated functions and energy efficiency optimization of ATV630 for process applications; for medium and large power pumping stations, it is recommended to directly choose ATV630.
Can the parameters of the two be copied directly?
No. The parameter structure and menu organization of the two series are different, and they need to be reset according to the actual load after replacement.
Is there a higher performance version of the ATV630?
Yes, ATV930 is designed for process applications that require higher dynamic performance and control accuracy, and can be further selected according to load characteristics.
How to confirm the specific model?
It is necessary to confirm the power, voltage class, structural form and degree of protection. Load parameters or photos of existing nameplates can be provided and we will assist in verifying the complete ordering code.
