Digital performance

Intelligent operation

Once installed, the AC drive monitors both its own performance, and the performance of its application. Logs of vital parameters and alarms facilitate preventive troubleshooting. Evaluation of the available internal data as well as external sensor signals takes place in the drive, and can be communicated further via fieldbus. All this information is available through protocols which match customer communication systems.

Danfoss AC drives also deliver a wealth of relevant process information, based on knowledge of the motor current reflecting the existing load conditions of the drive. The high quality of this data enables the drive to initiate action where required. Critical conditions such as over- or under-voltages, or small dips in the power supply from the grid, are detected and dealt with automatically.

Tools to check AC-drive performance

Use Danfoss’ range of simulation and calculation tools to help you understand how your drive is responding to its environment.

• Analyze harmonic disturbances 
• Estimate energy savings
• Calculate IE and IES efficiency classes in relation to the European Ecodesign Directive

Centralized control

For ease of installation and optimized operation, Danfoss drives are compatible with practically any control system.

Today’s AC drives are intelligent, which enables them to handle many tasks in drive systems. To exploit the full potential of the drives, you can quickly and easily integrate them into the control system by using any leading fieldbus or industrial Ethernet protocols. Full access to all objects of the installed drives is possible from a central control point. Cabling and commissioning are simpler, which leads to cost savings from the installation phase onward.

Better fault/alarm management

Detailed messages simplify the pin-pointing of possible fault/alarm causes and provide effective support for remote facility monitoring. Decoding of collective fault/alarm messages allows faults/alarms to be diagnosed and the right correction or maintenance actions to be initiated. Remote maintenance via an active internet connection allows state and/or fault/alarm messages to be displayed quickly, even with remote systems or system components.

Better asset management

Your assets can be operated from one central point – the control room – and processes regulate themselves according to the settings programmed in the control room. The operator has a clear overview of the current situation at all times and is able to monitor and adjust all drive settings remotely.

Details of drive assets, such as SN, FW, all settings, module revisions and applications, are easily accessible and can be backed up. Status data, such as the output frequency or power consumption, can be retrieved and processed at any time. Additional data for effective energy and peak load management is available without additional components.
