Motor overtemperature (T1/T2)

What does OH8 mean?

The motor temperature, measured via inputs T1 and T2, is too high. This signifies thermal overload due to impermissible continuous current or frequent/prolonged acceleration processes. It can also occur if terminals T1 and T2 are not connected to a PTC/temperature contact.
