Can someone explain how a Powerflex 525 drive interprets the PTC Thermistor signal from a motor winding? How does one know what the levels are or how the levels are defined for a given motor?
i.e. Normal / Fault / High Temp
I am guessing for a PTC type....
High Temp = High Resistance
Fault = low Resistance
OK= Nominal Resistance
Where do I find these resistance values from? Are there standard Thermistors used by motor manufactures? Nothing in the motor manual. And finally, can I get the status of the Thermistor input tied to a PowerFlex 525 if only Ethernet/IP protocol is being used for communicating with the drive. (No discrete signals)
Thanks
