3) Refer to the following table and set [ Pr. 83 and Pr.
84 ].
To enter the [ Pr. 92, 93 ] motor constants in [mH]
<Operating procedure>
1) Set the following value in [ Pr. 71 ]
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, 90 to 94, 859 ].
Calculate the [ Pr. 94 ] value from the following
formula.
[
Pr. 94
] Setting = (1- ) 100(%)
3) Refer to the following table and set [ Pr. 83, 84 ].
(6) Perform tuning of the second applied
motor
When you want to switch between two motors with
one inverter, set the second motor in [
Pr. 450 Second
applied motor ] (refer to page 266). Initial setting is
without second applied motor.
Turning the RT signal ON makes the following
parameters for the second motor valid.
To perform auto tuning of the second motor, replace
the parameter number stated in the previous
explanation with the parameter number
corresponding to the one for the second motor in the
table below.
