6.29.15 Parts replacement alarms
f634 : Annual average ambient temperature (Parts replacement alarms)
 Function
Calculate the remaining service life of the cooling fan, main circuit capacitor and on-block capacitor
based 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 displayed
and sent out through output terminals when each component is approaching the time of replacement.

● Display of part replacement alarm information
The time of replacement can be confirmed with the part replacement alarm information in the Status
monitor mode. (Refer to chapter 8)
An example of display:

Setting value 129 is reverse signal.
Note 1: Using f634 , enter the annual average temperature around the inverter. Be careful not to enter the
annual highest temperature .
Note 2: Set f634 at the time of installation of the inverter, and do not change its setting after the start of
use. Changing the setting may cause parts replacement alarm calculation error.
● The cumulative power on time, cumulative fan operation time and cumulative operation time until present
time 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) by
parameter typ (Refer to section 4.3.2) .
