P7.18
This function can be used for load change detection. Once the output terminal is set to "22: Zero Current
Detection Arrival", indication signal will be output upon the inverter output current is lower than the zero
current detection width P7.18.
Note: This function parameter is percentage of the inverter output current to rated current of the motor.
P7.19
This function is used for detecting the deviation between output frequency and setup frequency. Once
the output terminal function is set to "1: Frequency Arrival Signal", the deviation between the output
frequency and the setup frequency of the inverter is in the setup range of this function code and
indication signal is output, as shown in Figure 6−28 Frequency Arrival Signal FAR.
Yi represents Y1 terminal, Y2 terminal or relay terminal.
