Code Description
functions).
Use this setting when DRV-09 (Control mode) is set to “ 5 (Vector) ” .
Since the motor is rotating while the parameters are being
measured, if the load is connected to the motor spindle, the
parameters may not be measured accurately. For accurate
measurements, remove the load attached to the motor spindle.
If DRV-09 (Control mode) is set to “ 4 (Sensorless-2) ” , the rotor
time constant (Tr) must be measured in a stopped position.
2 All (static
type)
Measures all parameters while the motor is in the stopped
position, including stator resistance (Rs), stator inductance
(Lsigma), no-load current (Noload Curr), rotor time constant (Tr),
etc.
Use this setting when DRV-09 (Control mode) is set to “ 4
(Sensorless-2) ”.
Since the motor is not rotating while the parameters are
measured, the measurements are not affected when the load is
connected to the motor spindle.
3 Rs+Lsigma
Measures the stator resistance (Rs) and stator inductance
(Lsigma) while the motor is not rotating. The measured values
are used for auto torque boost and sensorless vector control.
Since the motor is not rotating while the parameters are
measured, the measurements are not affected when the load is
connected to the motor spindle.
4 Enc. Test
Runs auto tuning after installing the optional encoder to the
inverter and connecting the encoder cables to the motor. Auto
tuning checks the cable connection. Ensure that the encoder
related parameters are correctly set before auto tuning.
5 Tr
Uses this setting to measure the rotor time constant (Tr) when
DRV-09 (Control mode) is set to “ 5 (Vector) ” . The motor rotates
during auto tuning.
6 Tr (Stdstl)
Uses this setting to measure the rotor time constant (Tr) when
DRV-09 (Control mode) is set to “ 4 (Sensorless-2) ” . The motor
does not rotate during auto tuning.
BAS-14
Noload Curr,
BAS-21
Rs
– BAS-24 Tr
Displays motor parameters measured by auto tuning. For parameters that are not
included in the auto tuning measurement list, the default setting will be displayed.
• Perform auto tuning ONLY after the motor has completely stopped running.
• Before you run auto tuning, check the motor pole number, rated slip, rated current, rated
voltage, and efficiency on the motor’s rating plate and enter the data. The default parameter
setting is used for values that are not entered.
