In the following cases, the set value blinks for 3 s and the data
before changing is returned.
•
When a value exceeding the setting range is set
•
Set values of constants No. 32 and No. 33 are not in descending
order.
•
If the following conditions are not satisfied in the V/f constant set-
ting:
Maximum frequency (No. 02)
≥
Base frequency (No. 04) >
Intermediate frequency (No. 05)
≥
Minimum output frequency
(No. 07).
For the following setting, intermediate frequency voltage (No.
6) is disregarded:
Intermediate frequency = Minimum frequency.
For details, refer to
2-8-3 V/f Characteristic Setting.
•
If the following condition is not satisfied in the frequency refer-
ence constant setting:
Set frequency reference (Nos. 13 to 17)
≤
Maximum frequency
(No. 2)
For details, refer to
2-8-3 V/f Characteristic Setting.
•
If the following condition is not satisfied in the frequency refer-
ence upper/lower limit value setting:
Frequency reference lower limit value (No. 25)
≤
frequency ref-
erence upper limit value (No. 24).
