Hey Folks.
At our plants we've been talking about monitoring the current on motors through the VFD parameters to gather a bit of historical / highest amperage draw for each drive. Were thinking of using this as a bit of a basic diagnostic watch for early signs of machine failure, weather from mechanical influences or early motor failure itself.
I can create a trend and some basic alarms, but I'm wondering if anybody knows of a bit of of code from Rockwell or is there a specific algorithm you would use to determine that a motor is drawing an abnormal amount of current and simply not reacting to an ambient condition, process change or demand increase?
What have you done to illustrate or draw attention to motors/gearboxes that might be a risk to production? Aside form vibration analysis.
Thanks
