See also par. 16-90, 16-92 and 16-94.6.1.1. Warning/Alarm listWARNING 1, 10 Volts low:The 10 V voltage from terminal 50 on the con-trol card is below 10 V.Remove some of the load from terminal 50, asthe 10 V supply is overloaded. Max. 15 mA orminimum 590 ohm.WARNING/ALARM 2, Live zero error:The signal on terminal 53 or 54 is less than50% of the value set in par. 6-10, 6-12, 6-20,or 6-22 respectively.WARNING/ALARM 3, No motor:No motor has been connected to the output ofthe frequency converter.WARNING/ALARM 4, Mains phase loss:A phase is missing on the supply side, or themains voltage imbalance is too high.This message also appears in case of a faultin the input rectifier on the frequency convert-er.Check the supply voltage and supply currentsto the frequency converter.WARNING 5, DC link voltage high:The intermediate circuit voltage (DC) is higherthan the overvoltage limit of the control sys-tem. The frequency converter is still active.WARNING 6, DC link voltage lowThe intermediate circuit voltage (DC) is belowthe undervoltage limit of the control system.The frequency converter is still active.WARNING/ALARM 7, DC over voltage:If the intermediate circuit voltage exceeds thelimit, the frequency converter trips after atime.Connect a brake resistor.
