(2) Correctly power on for AIO;
(3) Confirm that the safety loop and lock loop are in a normal connected state;
(4) The Auto / Inspection (or emergency power operation) switch is in position of Inspection
(or emergency power operation):
(5) Select "induction motor self study" command by Seven-Segment Code Display
Manipulator or LCD handheld Manipulator, and then press the Enter key;
(6) AIO starts static self study: the main contactor between AIO and the motor will
automatically pull; AIO obtains internal characteristics parameters of the motor by applying
test current on the motor. But the brake contactor will not pull; neither will the motor rotate;
(7) The motor parameters complete their self study after 30 seconds, and the main contactor
releases automatically.
If the self study does not work, mainly check the following items:
(1) Whether the safety loop and the lock loop are connected. If not, the main contactor will
not pull, so it is impossible to complete the self study;
(2) Whether the Encoder wiring is correct, whether A, B phase is reversed;
(3) Whether the motor parameters are set correctly.
8.5 Test Run of Slow Car
8.5.1 Inspection Operation of Engine Room and Preparations for
Express Car
