Inspection
The life of the main circuit capacitor can not be measured in the following conditions:
³ The FR-HC, MT-HC, FR-CV, FR-BU, MT-BU5 or BU is connected.
· Terminals R1/L11, S1/L21 or DC power supply is connected to the terminal P/+ and N/−.
» Switch power on again during measuring.
¿ The motor is not connected to the inverter.
´ The motor is running. (The motor is coasting.)
² The motor capacity is two ranks (or more) smaller as compared to the inverter capacity.
¶ The inverter is at an alarm stop or an alarm occurred while power is off.
º The inverter output is shut off with the MRS signal.
¾ The start command is given while measuring.
Operating environment: Ambient Temperature (annual average 40°C (free from corrosive gas,
NOTE
For the accurate life measuring of the main circuit capacitor, perform after more than 3h
passed since the turn off of the power as it is affected by the capacitor temperature.
