G120C CONFIGURATION WITH PTC

However, the ptc will only be connected in the future. The question: is it possible to do this and inhibit failure in the G120C avoiding motor stop? Thanks!

If present motor has not any temp sensor, set p0601 = 0 which is default value. When you connect motor with PTC sensor, you need to modify related parameters, e.g. set p0601 = 1 i.e. sensor type is PTC & need to set time, fault response, switch ON delay time etc. etc. refer p605, p607, p606, p610 etc. etc. Hope this helps.

PTC connection would be in the future. In short: P0601=1 (PTC) P610=0 (no reaction, only warning) but PTC not connected to inverter. Question: This parameterization works for Open Circuit (no PTC connected). Thanks!

Overtemperature is evaluated above 1650ohm and short circuit under 20ohm so anything inbetween is ok i think.
