• For motor parameters, the Inverter inputs data on one phase of Y-connection at 50 Hz.
• Note the following before use:
•Set base frequency A003 and AVR voltage selection A082 according to the specifications of the
motor to be measured.
•The motor parameters can be determined for motors with the maximum applicable capacity or
one rank lower motor size. For motors with other capacities, correct constant data may not be
obtained. (In some cases, auto-tuning may not be completed. In this case, pressing the STOP/
RESET key displays an error message.)
•If DC injection braking selection A051 is set to "01" (enabled), the data cannot be measured
correctly. Be sure to set to "00" (disabled). (The default setting is "00" (disabled).)
•If "02" (auto-tuning with motor rotation) is selected in auto-tuning selection H001, note the
following:
•Make sure there is no problem even if the motor accelerates up to approx. 80% of the base
frequency.
•The motor is not driven by external equipment.
•The brake is released.
•During auto-tuning, the output torque is insufficient, which may cause an elevator system to
slip and fall. To prevent this, remove the motor from the load machine, and perform the auto-
tuning for the motor separately. (In this case, moment of inertia (J) is determined for the single
motor. You should add a motor shaft conversion value of the load machine's moment of
inertial to parameter J.)
