Gain a competitive edge with Danfoss AC Drives
The fourth Industrial Revolution, or Industry 4.0, builds on the progress of automation by introducing elements of interconnectivity, data acquisition, machine learning and intelligent application of analytics. AC drives play an important and powerful part in this transition by being the first point of interaction between sensors from the process, the motor in operation and then communicating this information to a central control location.
Energy savings – Energy savings are tied to the technology and the fact that applications need less energy when idle or operating with partial loads. Danfoss drives do the trick.
Fully automated operation – Danfoss drives enable a facility to increase its automation capabilities. Not every application is the same across all industries, but with customized programming, customers can determine what parameters are essential to their specific needs.
100% full load factory tested – Having received an order – a drive specified by the customer – Danfoss builds it and tests it against real motors before shipping.
A breakthrough in drive technology: VLT® with Condition based monitoring
Danfoss VLT® Drives with built-in intelligence can now monitor the condition of motors and applications, allowing you to detect deviations in baseline parameters early in order to proactively intervene before the deviations have a negative impact on your operations.

The Right VFD Cable Can Prevent Premature Motor Failure
VFD outputs can cause a non-VFD cable to broadcast noise that can affect nearby devices. Commonly used alternative products such as unshielded tray cables or THHN wire are not suited for this application and can cause your motors to fail prematurely.
Ozone will degrade PVC and can lead to a cable failure. For this reason, most VFD manufacturers recommend using cable with XPLE insulation with a minimum 20mil thickness. XPLE has a higher corona inception voltage and is not as likely to fail as a PVC insulated cable.
For any motor supply application involving a Variable Frequency Drive, we recommend LUTZE DRIVEFLEX® cables with XLPE insulation. These cables have very low capacitance, high impedance and high voltage breakthrough resistance.
