False alarm heating in motor 1ftk101

fernan Posts: 5 Rating: (0)	Hello. I have a problem with the engine temperature of a 1FK7101, looking at the temperature chart and says the engine is at 118 ° C, it really is 27 º C. We changed the control board and power module, without success.6SN1118 and 6SN1123 In another system of regulation has also proven that engine is ok by checking the actual temperature value. The next step is to change the monitoring module 6SN1112-1AC01. Someone can help me?

fernan Posts: 5 Rating: (0)	Hi Thanks for the reply. This same engine with the encoder cable (Z3 axis) I connect to another axis (Z2 axis) and the temperature measurement is correct. high temperature is always displayed in the Z3 axis, with different engines. So change the electronics (power and control) but without success.
