Procedure of Main circuit capacitor life measuring

1) Confirmation window appears before measuring. Check the
following items, and click
Motor is connected?
Motor is stopped?
Enough time has been passed after the motor operation?
2) Performs parameter setting for measuring the main circuit
capacitor life. Click
3) Switch OFF inverter power. Click
OFF the inverter.
4) After making sure that the POWER lamp of the inverter is off,
switch ON the power supply again. Click
powering ON the inverter.
5) Displays the measuring result of the main circuit capacitor life
in "Measured Value". (Displays a previous value in "Last
Value" if the main circuit capacitor life value measured last
time is stored in the inverter when updating diagnostic
information.)
REMARKS
When the main circuit capacitor life is measured under the following conditions, "forced end" (Pr.259="8") or "measuring error"
(Pr.259="9") occurs or it remains in "measuring start" (Pr.259="1"). Therefore, do not measure in such case.
(a) FR-HC, FR-CV are connected.
(b) DC power supply is connected to terminal P/+ and N/-.
(c) The power supply switched on during measurement.
(d) The motor is not connected to the inverter.
(e) The motor is running (coasting)
(f) The motor capacity is two rank smaller as compared to the inverter capacity.
(g)The inverter is tripped or a fault occurred when power is off.
(h) The inverter output is shut off with the MRS signal.
(i) The start command is given while measuring.
(j) The parameter unit (FR-PU04/FR-PU07) is connected (FR-D700, E700 series only)
(k) Use terminal PC as power supply (FR-D700, E700 series only)
(l) I/O terminal of the control terminal block and plug-in option is on (continuity) (FR-D700, E700 series only)
(m)Plug-in option is fitted. (only for the 0.75K or less of the FR-E700 series)
Turning the power on during measuring before LED of the operation panel turns off, it may remain in "measuring" (Pr. 259="2")
status. In such a case, perform life measurement again.
