The signal of the motor temperature sensor needs to be connected to the optional I/O extension card. This card is an
optional component. PG card also can be used for the temperature signal input with motor over-temperature
protection function. Please contact with manufacturer or distributors.
The PG card interface of the EM15 supports both PT100 and PT1000. Set the sensor type correctly during the use.
You can view the motor temperature via parameter U0-34.
If the motor temperature exceeds the value set in bb-26, the frequency inverter reports an alarm and acts according to
the selected fault protection action.
If the motor temperature exceeds the value set in bb-27, the DO terminal of frequency inverter set with motor
overheat warning becomes ON.

Overvoltage threshold
Default
Model dependent
Setting Range
200.0~2500.0 V
It is used to set the overvoltage threshold of the frequency inverter. The default values of different voltage classes are
