2 : ALL (Stdstl)
Chapter 8 Applied Functions
Motor parameter is measured when motor is stopped. Measure stator resistance(Rs), leak inductance(Lsigma), and the
rotor time constant(Tr) all together at the same time. This mode is available when Control Mode(DRV-09) is Sensorless-2.
3 : Rs+Lsigma
The parameter is measured with the motor not operating. The measured values are used for auto torque boost and
sensorless vector control. Because the motor is not rotating, the connection between the motor axis and load does not
affect the parameter measurement. However, be careful not to rotate the motor axis at the load side.
4 : Enc. Test
Connect the encoder option card to the main body of the inverter and connect the encoder cable attached to the motor to
the option card. The motor checks connection and misconnection of A and B pulses. Be sure to set related functions
correctly for encoder state measurement.
5 : Tr
When Control Mode(DRV-09) is Vector, the motor measures the rotor time constant(Tr) while rotating. If Control
Mode(DRV-09) is Sensorless-2, the motor measures the rotor time constant(Tr) while static.
If Control Mode(DRV-09) shifts from Sensorless2 to Vector, you should conduct time constant(Tr) tuning again.
BAS-21 Rs ~ BAS-24 Tr, BAS-14 Noload Curr : Displays the motor parameter measured in auto tuning. Of the auto tuning
selected above, for the parameter missing from the measurement items, the default value is displayed.
