F_76 0.00 to 50 MOTOR 1 (%X Setting) Std. 4-pole
This function displays the leakage reactance X1 of the motor
motor in terms of percentage, and is set manually
The data can be overwritten and changed automatically
by automatic tuning using function F_74, or by setting
the motor capacity, rated current and no-load current
using functions F_70 to F_72.
Calculation Formula for %X1
X1 + X2 = Xm/ (X2 + Xm) + cable X
%X1 = x 100 [%]
V / ( 3 • I)
X1: Primary inductance of motor 1[Ohm]
X2: Secondary inductance of motor 1 [Ohm]
Xm
: Mutual inductance of motor 1 [Ohm]
Cable X: [Ohm]
V: Rated voltage of motor
I: Rated current of motor
: Value calculated for Y connection
%R1 and %X1 should be set to values which are appropriate
for the motor being used. The motor may not operate
correctly if these values are not set correctly, which could
result in accidents.
