Motor Thermal Protection
However, having a motor fitted with thermal winding protection is only part of the solution. If the thermal winding protection is not connected to a monitoring device or circuit, then the thermal winding protection is irrelevant. Fortunately, KEB VFDs have a T1 and T2 (or T+ and T-) terminal for the connection of a thermal winding …
