User Manual of EM730 Series Inverter When the input terminal is set to “122: wiring detection signal”, F27.27 ~ F27.29 will be valid. When the output frequency of the inverter reaches the set value of F27.27, wiring detection will be started. If the wiring detection terminal is valid within the set time of F27.28, the wiring switch will be considered invalid. If the wiring detection terminal is always valid within the set time of F27.29, the wiring pole will stop moving. If the wiring pole protection is detected, the inverter will report E44 protection and stop freely. The set time of this function is the filtering time of material cutoff detection.
It is valid simultaneously for automatic material cutoff detection and external material cutoff detection. This function code is used to view the current feedforward gain.
