1. The acceleration/deceleration time constant is too small. Increase the acceleration/deceleration time constant. ?

2. The torque limit set by the controller is too small. Increase the torque limit. ?

3. Lack of torque due to power supply voltage drop?

The motor will not start. ?

1. Check the power supply capacity. ?

2. Adopt a servo motor with higher power. ?

4. What is the model loop gain of1(parameter number PB07)?

It is too small. ?

Increase the set point and make adjustments to ensure correct operation. ?

5. The servo motor shaft rotates under the action of external force. 1. When the torque is limited, increase the limit value. ?

2. Reduce the load. ?

3. Adopt a servo motor with higher power. ?

6. Mechanical collision. 1. Check the running mode. ?

2. Install the limit switch. ?

7. If the encoder fails, please replace the servo motor. ?

8. The servo motor is not connected correctly. The output of the servo amplifier?

Output terminals u, v, w and input terminals of servo motor?

The children u, v and w do not match. ?

Connect correctly. ?

Too many errors, model position and actual servo?

Deviation between motor positions?

Exceeding the parameter number PC0 1?

Set value (initial value: 3?

Turn). ?

9.SSCNET cable failure Replace SSCNET cable.
