 Hello Ammuu,

Have you read earlier replies in this post? Please provide detail information like, is the drive with PTC sensor or I2t calculated temperature,? does motor really getting hot or only drive trips ob F11? Is drive of proper size?, how much value is displayed at r0035? etc. etc

I am having the same problem. I get the F11 error and motor instantly stops. However the motor is water cooled and everything is stone cold (including motor cable). Is there a way to disable this error? Because it really does not help.

Hello,

F11 or motor temp is calculated by formula I2T in VFD based on motor data enetered. So please check if motor data is entered correctly as per motor winding connection, motor is not overloaded, number of start/stops are not more (i.e. 4 nos/hr for S1 duty) 

Since in your case motor is water cooled, please check value set in p0335 & p0604. In p0335 must be 1 & p0604 must be 130.
