Offline auto tuning (Pr. 80 to Pr. 96)

4.12.4 Utilizing or changing offline auto tuning data for use

<Setting the motor constants as desired>
Pr. 90 to Pr. 94 (Pr. 458 to Pr. 462) (motor constants) may be set as desired in either of two ways; the data
measured in the offline auto tuning are read and utilized or changed, or the motor constants are set without the
offline auto tuning data being used.
<Operating procedure>
1. Set the following value in Pr. 71 (Pr. 450):
• Standard motor ............................................................................................. Pr. 71 (Pr. 450) = "4"
• Constant-torque motor.................................................................................. Pr. 71 (Pr. 450) = "14"
• SF-JR (4P) (1.5kW(2HP) or less) ................................................................. Pr. 71 (Pr. 450) = "24"
• Vector control dedicated motor ..................................................................... Pr. 71 (Pr. 450) = "34"
2. Set "801" in Pr. 77.
(The parameter values of Pr. 82 (Pr. 455) "motor excitation current" and Pr. 90 to Pr. 94 (Pr. 458 to Pr. 462)
(motor constants) can be displayed. Though the parameter values of other than Pr. 82 (Pr. 455) and Pr. 90 to
Pr. 94 (Pr. 458 to Pr. 462) can also be displayed, they are parameters for manufacturer setting and their values
should not be changed.)
3. In the parameter setting mode, read the following parameters and set desired values.

REMARKS
When "0" (factory setting) is set in Pr. 684 "tuning data increment switchover", the motor constants are set in "internal variable
increment". When "1" is set in Pr. 684, the motor constants are set in "mH,
4. Return the Pr. 77 setting to the original value.
REMARKS
1. Set "9999" in Pr. 90 to Pr. 94 (Pr. 458 to Pr. 462) to use the standard motor constants (including those for the constant-
torque motor).
2. Set "3 (standard motor), "13" (constant-torque motor) or "23" (SF-JR(4P) 1.5kW(2HP) or less) in Pr. 71 to use the
constants measured in the offline auto tuning. Set "4, 14 or 24" in Pr. 71 (Pr. 450) and change the motor constants to
change the values measured in the offline auto tuning.
3. As the motor constants measured in the offline auto tuning have been converted into internal data (****), refer to the
following setting example when making setting:
Setting example: To slightly increase Pr. 90 (Pr. 458) value (5%)
When Pr. 90 (Pr. 458) is displayed "2516", set 2642, i.e. 2516 × 1.05=2641.8, in Pr. 90 (Pr. 458). (The value displayed has
been converted into a value for internal use. Hence, simple addition of a given value to the displayed value has no
significance.)
4. When "1" is set in Pr. 96 (Pr. 463), the last values of Pr. 82, Pr. 92, and Pr. 93 (Pr. 455, Pr. 460, Pr. 461) remain
unchanged.
