代碼 dv3: Inversion Detection

Code type: Fault Manual section: Yaskawa A1000 Troubleshooting The Z pulse offset is not set properly to E5-11. Set the value for Δθ to E5-11 as specified on the motor nameplate. Replacing the PG encoder or changing the application so that the motor rotates in reverse instead requires readjustment of the Z pulse offset. (T2-01 = 3) An external force on the load side has caused the motor to move. - Make sure the motor is rotating in the right direction. - Look for any problems on the load side that might be causing the motor to rotate in the opposite direction. Electrical signal interference along the PG cable affecting the A or B pulse. Rewire the PG encoder and make sure all lines including shielded line are properly connected. PG encoder is disconnected, not wired properly, or the PG option card or PG itself is damaged. Rotational direction for the PG encoder set to F1-05 is the opposite of the order of the motor lines. Make sure motor lines for each phase (U, V, W) are connected properly.
