Corrective maintenance
8.1 Replacing inverter components
Replacing the inverter with data backup in the operator panel (BOP-2 or IOP)
Procedure
To replace the inverter, proceed as follows:
1. Disconnect the line voltage to the inverter and (if installed) the external 24 V supply or the
voltage for the digital outputs of the inverter.
2. Remove the connecting cables of the inverter.
3. Remove the defective inverter.
4. Install the new inverter.
5. Connect all of the cables to the inverter.
6. Reconnect the line voltage, and (if being used) the external 24 V supply or the voltage for
the digital outputs of the inverter.
7. Attach the operator panel to the inverter.
8. Transfer the settings from the operator panel to the inverter, e.g. via menu "EXTRAS" -
"FROM BOP" in the BOP-2.
9. Wait until the transfer is complete.
10.After loading, check whether the inverter outputs alarm A01028.
– Alarm A01028:
– No alarm A01028: Proceed with the next step.
11.Switch off the inverter supply voltage.
12.Wait until all LEDs on the inverter go dark.
13.Switch on the inverter supply voltage again.
The inverter reports the faults F01641, F01650, F01680 and F30680. Ignore these faults,
as they will be automatically acknowledged by the following steps.
14.Set p0010 to 95.
15.Set p9761 to the safety password.
16.Set p9701 to AC hex.
17.Set p0010 to 0.
18.Back up the settings so they are not lost when the power fails:
– For BOP-2, in the menu "EXTRAS" - "RAM-ROM".
– For IOP, in the menu "SAVE RAM TO ROM".
19.Switch off the inverter power supply.
20.Wait until all LEDs on the inverter are dark.

The loaded settings are not compatible with the inverter.
Clear the alarm with p0971 = 1, and recommission the drive.
