Getting Ahead of Unplanned Downtime with Predictive Analytics

Predictive Analytics Changes the Equation for High-Power Drive Applications

You’ve heard of the Industrial Internet of Things (IIOT), and drives are one of the “things” in the IIOT.

Today, drives with built-in predictive analytics can prevent significant unplanned downtime. For example, drives have built-in cooling fans to keep them from overheating. If one of those cooling fans stops working, the drive will overheat and fault, which, you guessed it, causes unplanned downtime.

TotalFORCE® technology is one way of solving this problem by modeling the fan’s predicted life. This analytical model is more than a simple counter – it takes into account measured ambient temperature (sensors are built into drive modules) and measured fan speed. Decreasing fan speed is an indicator that the fan’s bearings are failing.

The predictive maintenance model gives a notification over EtherNet/IP to the control system once the fan has reached a certain percentage of its predicted life – 80% by default.

A connected system can give the maintenance team a notification to replace the fan during the next scheduled outage, thereby avoiding the unscheduled downtime scenario.

Furthermore, a connected system can be used to automatically check inventory of replacement parts and order if necessary.

Additional Predictive Models

The technology also includes predictive models for capacitors and IGBTs (Insulated Gate Bipolar Transistors) that make up the power module of the drive.

These predictive models take into account factors such as ambient temperature, heat sink temperature and loading.

Once again, the drive is designed to give a notification when those components get close to the end of their predicted life.

Analytical Capabilities Maximize Uptime

These analytical capabilities allow users to avoid unplanned downtime scenarios like the tissue machine in the beginning of this blog.

In addition, the predictive models allow users to optimize their maintenance spend.

For example, when one drive on a machine is running lightly loaded for most of its operation, the power module will need to be replaced much later in its life compared to a drive running at full load and higher temperature.

When you have all the information on your devices connected to your operations, you can better plan for your maintenance spend.

Predictive maintenance capabilities are just one way that TotalFORCE technology helps address challenges with high-power drive applications.
