Vi Analog Input Break Detection; Parts Replacement Alarms; Vi Analog Input Break Detection Level - Toshiba TOSVERT VF-nC3E Instruction Manual

6.18.13 VI analog input break detection

 : VI analog input break detection level
 Function
The inverter will trip if the VI value remains below the specified value for about 0.3 seconds. In such a
case, "" is displayed.
=0: Disabled....Not detected.
=1-100....The inverter will trip if the VI input remains below the specified value for about 0.3 seconds.



VI analog input break detection level

Note : The VI input value may be judged earlier to be abnormal, depending on the degree of deviation of the
analog data detected.

6.18.14 Parts replacement alarms

 : Annual average ambient temperature (Parts replacement alarms)
 Function
You can set the inverter so that it will calculate the remaining useful lives 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 time of replacement.

★ Display of part replacement alarm information
Part replacement alarm information (Refer to page H-4) in the Status monitor mode allows you to check
on the time of replacement.
An example of display:

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 parts replacement alarm calculation error.
