Internal storage device fault (E.PE6)
The operation of the storage device in the inverter can be checked.
If a data fault occurs in the storage device in the inverter, the protective function (E.PE6) is activated.
When the read value of
Pr.890
is "7" or smaller, an inverter reset after All parameter clear can return the operation to
normal. (The parameters that had been changed before All parameter clear must be set again.)
*1
For example, when parameter clear, All parameter clear, Parameter copy, or offline auto tuning is performed in the inverter, or when
parameter batch write is performed in FR Configurator2.
NOTE
• "E.PE6" does not activate the retry function.
• "E.PE6" outputs the Fault output 3 (Y91) signal.
• "E.PE6" turns OFF the Safety monitor output (SAFE) signal.
• "E.PE6" is not cleared by turning ON the Fault clear (X51) signal.
• The communication data code for "E.PE6" is 172 (HAC).
Checking faulty area in the internal storage device
When E.PE6 occurs, faulty area in the internal storage device can be checked by reading
Pr.890
.
• Use the read value of
Pr.890
to check the faulty area.
• The following table shows faulty areas indicated by the read value of
Pr.890
. Some read values indicate that there are multiple
faulty areas. (For example, the read value "7" indicates that all the areas described in No. 1 to No. 3 are faulty.)

Name
Internal storage device fault
Description
This protective function is activated by an inverter reset if writing data fails due to power-OFF or a data
fault occurs in the storage device during parameter operations
*1
.
Check point
Check if the power was turned OFF during parameter operations.
Corrective action
Check the power supply or the devices on the power system to check that the devices have no fault.
• When E.PE6 occurs due to power-OFF during parameter operations:
Check the read value of
Pr.890
. When the value is "7" or smaller, perform All parameter clear and
then an inverter reset. The parameters that had been changed before All parameter clear must be
set again.
• When E.PE6 occurs due to other reason (such as turning OFF/ON the power or an inverter reset):
Contact your sales representative.
