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.

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.￿

6.33.20Rush current suppression relay activation time

￿￿￿￿￿: Rush current suppression relay activation time

• 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.

	activation time

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.
