6.33.19 Guide to time of replacement

 : Annual average ambient temperature
• Function
You can set the inverter so that it will calculate the remaining useful life of the cooling fan, main circuit
capacitor and on-board capacitor from the ON time of the inverter, the operating time of the motor, the
output current (load factor) and the setting of  and that it will display and send out an alarm through
output terminals when each component is approaching the end of its useful life.
Title

Note 1: Using , enter the annual average temperature around the inverter. Be careful not to enter the
annual highest temperature.
Note 2: Set  at the time of installation of the inverter, and do not change its setting after the start of use.
Changing the setting may cause a part replacement alarm calculation error.

6.33.20 Rush current suppression relay activation time

 : Rush current suppression relay activation time
6
• Function
This parameter is used to control the rush current suppressing resistor shorting relay when a direct current
is passed or multiple inverters are used with their DC sections connected to each other.
Title

The rush current suppressing relay is activated on the expiration of the time limit set with parameter  after the
voltage in the DC section of the inverter has reached the specified level.
