This chapter provides information on the use of advanced functions of the Inverter for
operation.
Refer to this chapter to use the various advanced functions, such as precise vector con-
trol setting, energy-saving control, PID control, carrier frequency setting, DC injection
braking, stall prevention, overtorque detection, torque compensation, and slip com-
pensation.

Precise Vector Control Settings and Adjustments
6-1-1 Precise Vector Control Settings
•
In addition to the settings described in
5-2 Operation in Vector Control
, check the motor test report and
precise motor constants and make the following settings in order to make full use of the Inverter in
vector control.
H
Setting the Motor Phase-to-neutral Resistance (n107)
•
Set this parameter to 1/2 of the phase-to-phase resistance or phase-to-neutral resistance of the motor
at 50
°
C.
•
Obtain from the manufacturer of each motor the test report of the motor or equivalent datasheet
including precise specifications of the motor. Use the the applicable formula from those listed in the
following and calculate the phase-to-neutral resistance at 50
°
C from the insulation class and phase-
to-phase resistance of the motor described in the test report.
Insulation class E: Phase-to-phase resistance at 75
°
C (
Ω
) x 0.92 x 1/2
Insulation class B: Phase-to-phase resistance at 75
°
C (
Ω
) x 0.92 x 1/2
Insulation class F: Phase-to-phase resistance at 115
°
C (
Ω
) x 0.87 x 1/2

Note 1.
The value will be set in 0.001-
Ω
increments if the resistance is less than 10
Ω
and 0.01-
Ω
increments if the resistance is 10
Ω
or over.
Note 2.
The default setting for this parameter is the standard phase-to-neutral resistance of the maxi-
mum applicable motor.
H
Setting the Motor Leakage Inductance (n108)
•
Set the motor leakage inductance in 1-mH increments.
•
Motor leakage inductance is a magnetic field that is leaking externally or consumed as core loss, and
is not used for torque generation.
•
To insert an AC reactor for surge suppression into the output side of the Inverter, set this parameter to
the motor leakage inductance added with the inductance of the AC reactor.
•
The Inverter fully functions in vector control with the default setting for motor leakage inductance.
Therefore, set this parameter only if the motor leakage inductance is known.
