5.7.9
When E.PE6 (Internal storage device fault) occurs, faulty area in the internal storage device can be checked by reading Pr.890.
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.)

• Pr.890 read
• 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.)

 Setting the maximum frequency (Pr.1, Pr.18)
• Set Pr.1 Maximum frequency to the upper limit of the output frequency. If the value of the frequency command given is
higher than the setting, the output frequency is clamped at the maximum frequency.
• To operate at a frequency higher than the 120 Hz, adjust the upper output frequency limit with Pr.18 High speed
maximum frequency. (When setting a frequency in Pr.18, the Pr.1 setting automatically changes to the frequency set in
Pr.18. Also, when setting a frequency in Pr.1, the Pr.18 setting automatically changes to the frequency set in Pr.1.)
