If the output current of the frequency inverter is within the positive and negative amplitudes of any current
reaching detection value, the corresponding DO becomes ON.
The EM11 provides two groups of any current reaching detection parameters, including current detection
value and detection amplitudes, as shown in the following figure.

75°C
When the heatsink temperature of the frequency inverter reaches the value of this parameter, the
corresponding DO becomes ON, indicating that the IGBT module temperature reaches the threshold.

These two parameters are used to set the limits of the input voltage to provide protection on the frequency
inverter. When the AI1 input is larger than the value of b5-06 or smaller than the value of b5-05, the
corresponding DO becomes ON, indicating that AI1 input exceeds the limit. Every analog input has five
setting points to facilitate the setting of the AI curve.
