10.4 Output phase loss protectionGroup Code Parameter Set Range Initial UnitFunctiongroup 2H19[Input/Output phase lossprotection select]1 0 ~ 3 0• Set H19 value to 1.• Output phase loss: Inverter output is shut off at the event of more than one phase lossamong U, V and W.• Input phase loss: Inverter output is blocked at the event of more than one phase lossamong R, S and T. If there is no input phase loss, output is shut off when it is time to replaceDC link capacitor.CAUTIONSet H33 [Motor rated current] correctly. If the actual motor rated current and the value of H33are different, output phase loss protection function could not be activated.H19[Input/Outputphase lossprotection select]0 Not used1 Output phase loss protection2 Input phase loss protection3 Input/output phase loss protection10.5 External trip signalGroup Code Parameter Set Range Initial UnitI/OgroupI17[Multi-function input terminal P1define]0 ~ 250~ ~I23I24[Multi-function input terminalP7 define][Multi-function input terminalP8 define]18 6197• Select a terminal among P1 thru P8 to output external trip signal.• Set I23 and I24 to 18 and 19 to define P7 and P8 as External A contact and B contact. External trip signal input A contact (N.O.): Normal open contact input. When a P7 terminal setto “Ext trip-A” is ON (Closed), inverter displays the fault and turns off its output. External trip signal input B contact (N.C.): Normal close contact input. When a P8 terminal setto “Ext trip-B” is OFF (Open), inverter displays the fault and turns off its output.10-5
