PTC Tripping Resistance
I have ACS880 Drive and PTC connected on DI6, during commissioning i was testing it by removing the PTC wires and realized that the drives only gave "Warning", so i checked the configuration and noticed that there are two parameters,
35.12 Temperature 1 fault limit (Default 4500 Ω)
35.13 Temperature 1 warning limit (Default 4000 Ω)
so i changed them to be,
35.12 Temperature 1 fault limit (1800 Ω)
35.13 Temperature 1 warning limit (1500 Ω)
this time, the drive gave"Fault"
my question is, whey the dive didn't give "Fault" before changing the default values (Open loop >> 4500Ω)??
