3) In the parameter setting mode, read the following
parameters and set desired values. Mitsubishi
motor constants are used when 9999 is set in [Pr.
82, Pr. 90 to Pr. 94, Pr. 859].

Constants measured by offline auto tuning are used
when [Pr. 71 = 3, 13, 23, 33, 43, 53] are set. Constants
measured by offline auto tuning is overwritten when
the motor constants are changed after the [Pr. 71] is
set to "4,14,24,34,44,54"
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] value (5%)
When [Pr. 90 = 2516] is displayed, set

2642].
(The
converted into a value for internal use.
Hence, simple addition of a given
value to the displayed value has no
significance.)

(5) Setting
A700
When setting the motor constants without using
offline auto tuning data, the [Pr. 92, Pr. 93] motor
constants may either be entered in [
Before starting operation, confirm which motor
constant unit is used.
To enter the [Pr. 92, Pr. 93] motor constants in [
<Operating procedure>
1) Set the following value in [Pr. 71]. If "star connection"
is mistaken for "delta connection" or vice versa during
setting of [Pr. 71], General-purpose magnetic flux
vector control, Advanced magnetic flux vector control,
Real sensorless vector control, and vector control
cannot be performed properly.

Setting
* When [Pr. 71 = 7, 8, 17, 18] in
the motor constants directly, offline auto tuning
can be performed.
2) In the parameter setting mode, read the following
parameters and set desired values. Mitsubishi
motor constants are used when 9999 is set in [Pr.
82, Pr. 90 to Pr. 94, Pr. 859]. Use the following
formula to find [Pr. 859 Torque current].
