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.
