Motor Constant Measuring Function

・During vector control or when auto torque boost or slip compensation is
performed through V/F control, motor constant can be set through "automatic
tuning" or specified as values recommended by our company.
Setting value

・Please perform automatic tuning when the motor is fully stopped.
・ Please perform automatic tuning of slip compensation frequency when
there is no load on the motor shaft.
・Acceleration time for automatic tuning of slip compensation frequency can
248
・When automatic tuning of voltage compensation
constant starts, the inverter will automatically apply
DC high-voltage to the motor. Therefore, do not
approach the unit.
Failure to do so may result in electric shock.
・When automatic tuning of slip compensation freuqncy
starts, the inverter will drive the motor at 60 Hz.
Therefore, do not approach the unit.
Failure to do so may result in injury.
It indicates the value in normal status.
* The value is set in case that automatic tuning mode status for setting
value "1" and "2" is cancelled.
When voltage compensation constant is set to automatic tuning mode:
When the inverter returns to operation status display mode and enters
measurement status after data setting, the constant measurement can
be started by pressing RUNSW button.
When slip compensation constant is set to automatic tuning mode:
When the inverter returns to operation status display mode and enters
measurement status after data setting, the constant measurement can
be started by pressing RUNSW button.
Constants recommended by our company will be assigned to "P133:
Voltage Compensation Constant" and "P134: Slip Compenstion
Frequency" according to the setting values of "P130: Motor Capacity"
and "P131: Motor Pole Number". (If constants for P133 and P134 are
changed after data setting, the setting value will become "0"
automatically.)
