For the 5.5K and 7.5K, the Pr. 0 and Pr. 12 settings are automatically changed depending on the Pr. 71
setting.
Pr. 71 0, 2, 3 to 8, 20, 23, 24
Pr. 0 3%
Pr. 12 4%
Note: 1. When "9999" is set in Pr. 19, "2" cannot be set in Pr. 71. To set "2" in Pr. 71, set the appropriate
value (other than "9999") in Pr. 19.
2. When "2" is set in Pr. 71, Pr. 100 to Pr. 109 are displayed on the parameter unit (FR-PU04). In
other settings, if any of Pr. 100 to Pr. 109 settings is changed, the new setting is not displayed in
the "Default parameter list" and "Set parameter list".
3. Refer to Pr. 96 for offline auto tuning.
4. Set any of "3, 7, 8, 13, 17 and 18" to perform offline auto tuning.
Set this parameter correctly according to the motor used.
Incorrect setting may cause the motor to overheat and burn.
