1. Analysis of the causes of Yaskawa servo alarm C90 (AC9):
1. The encoder cable is broken or the encoder plug is made in poor process (there are also wiring errors in the alarm of the new machine);
2. The servo drive itself is faulty;
3. Environmental interference, caused by poor connection: such as high-power high-frequency interference equipment (pressur, inverter) in the working environment
4. The feedback unit of the servo motor encoder is faulty.
Second, the treatment method:
1. Check whether the encoder cable is good, and carefully check whether the plug, soldering point and cable bow and foot arrangement of the encoder are normal;
2. If you don't find the problem of wires and plugs, and then rule out the interference problem of the encoder cable, please separate the coding cable from other wires (power cables);
3. The interference problem of the line is good and solved, replace a new encoder line to try, no alarm appears after the replacement, and the follow-up needs to be tracked for 1-2 days;
4. If the encoder line alarm is replaced, then replace the motor - a power on to try it, the alarm will be eliminated after the replacement, and the faulty motor will be taken to the maintenance center for testing;
5. If the alarm cannot be eliminated after replacing the motor, then take the driver to detect.

Yaskawa Electric – inspection work before motor operation
(1) Check and remove the dust and debris on the motor;
(2) Check whether the voltage, frequency and power supply voltage and frequency on the nameplate of the motor are consistent with the actual situation, and whether the connection method is correct.
(3) Use the insulation resistance meter to measure the phase and phase and phase of the motor winding.

Wiring method of Yaskawa A1000 inverter
First, the wiring of the main circuit
1. The power supply should be connected to the R, S, and T terminals at the input end of the inverter, and must not be connected to the output terminal (U, V, W) of the inverter, otherwise the inverter will be damaged. After wiring, the fragmented wires must be cleaned, and the fragmented wires may cause abnormalities.
