E6581611F-11266.29.15 Parts replacement alarmsf634 : Annual average ambient temperature (Parts replacement alarms)• FunctionCalculate the remaining service life of the cooling fan, main circuit capacitor and on-block capacitorbased on the cumulative power on time, cumulative operation time, cumulative fan operation time,the output current (inverter load factor) and the setting of f634. An alarm will be monitor displayedand sent out through output terminals when each component is approaching the time of replacement.[Parameter setting]Title Function Adjustment range Default settingf634 Annual average ambient temperature(parts replacement alarms)1: -10 to +10°C2: 11-20°C3: 21-30°C4: 31-40°C5: 41-50°C6: 51-60°C3+ Display of part replacement alarm informationThe time of replacement can be confirmed with the part replacement alarm information in the Statusmonitor mode. (Refer to chapter 8)An example of display: + Output of part replacement alarm signalThe parts replacement alarm is assigned to the output terminal.Setup example) When the parts replacement alarm is assigned to the OUT terminalTitle Function Adjustment range Settingf131 Output terminal selection 2A(OUT) 0-255 128: LTA (Parts replacementalarm)Setting value 129 is reverse signal.Note 1: Using f634, enter the annual average temperature around the inverter. Be careful not to enter theannual highest temperature.Note 2: Set f634 at the time of installation of the inverter, and do not change its setting after the start ofuse. Changing the setting may cause parts replacement alarm calculation error.+ The cumulative power on time, cumulative fan operation time and cumulative operation time until presenttime can be checked by setting status monitor mode. (Refer to chapter 8)+ The monitor value of cumulative fan operation time and cumulative operation time are reset to 0(zero) byparameter typ (Refer to section 4.3.2) .
