Program features 149SettingsParameters 3013 UNDERLOAD FUNC, 3014 UNDERLOAD TIME and 3015UNDERLOAD CURVE Earth fault protectionThe Earth fault protection detects earth faults in the motor or motor cable. Theprotection can be selected to be active during start and run or during start only.An earth fault in the input power line does not activate the protection.SettingsParameter 3017 EARTH FAULT Incorrect wiringDefines the operation when incorrect input power cable connection is detected.SettingsParameter 3023 WIRING FAULT Input phase lossInput phase loss protection circuits supervise the input power cable connection statusby detecting intermediate circuit ripple. If a phase is lost, the ripple increases.SettingsParameter 3016 SUPPLY PHASEPre-programmed faults OvercurrentThe overcurrent trip limit for the drive is 325% of the drive nominal current. DC overvoltageThe DC overvoltage trip limit is 420 V (for 200 V drives) and 840 V (for 400 V drives). DC undervoltageThe DC undervoltage trip limit is adaptive. See parameter 2006 UNDERVOLT CTRL. Drive temperatureThe drive supervises the IGBT temperature. There are two supervision limits: Alarmlimit and fault trip limit.
