5.7.9 Checking faulty area in the internal storage device
When Internal storage device fault (E.PE6) 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. Name
890 Internal storage device status
H325 indication
• 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.)
No. Read value
1 1, 3, 5, 7 Storage area other than the area for parameter settings is faulty (such as area for the set frequency).
(When All parameter clear is performed, the set frequency, remotely-set frequency, host name for
Ethernet communication, and offline auto tuning data are cleared.)
2 2, 3, 6, 7 Storage area for standard parameter settings is faulty.
3 4, 5, 6, 7 Storage area for communication parameter settings is faulty.
4 8 to 511 Area for manufacturer setting
5.7.10 Limiting the output frequency (maximum/minimum
frequency)
Motor speed can be limited. Clamp the output frequency at the upper and lower limits.

1 Maximum frequency
H400
2 Minimum frequency
H401
18 High speed maximum frequency
H402
*1 For the FR-F860-00680 or lower.
*2 For the FR-F860-01080 or higher.
 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 entered
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.)
