Selection and protection of a motor
(5) Method to set the motor constants without using the offline auto tuning data
The
Pr. 90
to
Pr. 94
motor constants may either be entered in [
Ω
] or in [mH]. Before starting operation, confirm which motor
constant unit is used.
To enter the
Pr. 90
to
Pr. 94
motor constants in [
Ω
]
<Operating procedure>
1)Set
Pr. 71
according to the motor used.
2)In the parameter setting mode, read the following parameters and set desired values.
3)Refer to the following table and set
Pr. 83
and
Pr. 84
.

REMARKS
When "9999" is set in
Pr. 82
,
Pr. 90
to
Pr. 94
,
Pr. 859
, Mitsubishi motor (SF-JR, SF-HR, SF-JRCA, SF-HRCA) constants are used.
NOTE
y
If "star connection" is mistaken for "delta connection" or vice versa during setting of
Pr. 71
, Advanced magnetic flux
vector control and General-purpose magnetic flux vector control cannot be exercised properly.
