4-2 Function Mode •For motor parameters, the Inverter inputs data on one phase of Y-connection at 50 Hz. 4 Functions •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.) 4-107 Parameter No. Function name Data Default setting Unit H001 Auto-tuning selection 00: Disabled 01: Enabled (Motor does not rotate.) 02: Enabled (Motor rotates.) 00 H002/H202 Motor parameter selection 00: Standard motor parameter 01: Auto-tuning parameter 02: Auto-tuning parameter (Online auto-tuning enabled.) 00 H003/H203 Motor capacity selection 0.2 to 75.0 Factory default kW H004/H204 Motor pole number selection 2/4/6/8/10 4 Pole H030/H230 Motor parameter R1 (auto-tuning data) 0.000 to 65.53 Depends on the motor capacity.
