selection
A082 AVR voltage selection
•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.)
•With a machine (e.g. lift, ball screw) whose motor shaft rotation is limited, the machine may
be damaged if the allowable rotation limit is exceeded. In this case, set H001 to "01" (auto-
tuning without motor rotation).
•With a motor whose no-load current is unknown, measure the current at 50 Hz in the "V/f
setting" mode, and perform auto-tuning after setting the current value in H023/H223.
•Even if "01" (auto-tuning without motor rotation) is selected in H001, the motor may slightly
rotate.
•To perform auto-tuning for one rank lower motor size, enable the overload limit function and set
the overload limit level to 1.5 times the rated current of the motor.
