Debugging of Typical Problems
I. (Run) the enable green lamp fails to be on.
a. Check whether the voltages of three phases R, S and T are normal.
b. Check whether the +24V for Pin 18 of CN1 interface is correct.
c. Check whether Pin 10 of CN1 interface is connected with 0V.
d. If the above all are normal and the green lamp still fails to be on, try again by using the internal enable
PA53=0001.
II.
Alarms―Err—9,Err—15,Err—30,Err—31,Err—32
‖
appears.
A photoelectric encoder is a very typical fragile, sensitive component, so it should be protected in every
aspect.
a.The above alarms indicate that the encoder or the wiring of the encoder is abnormal.
b. Check whether both ends of the shielding layer are well grounded.
c. Check that whether a too long wire will lead to attenuation to 5V power supply of the encoder.
d. The photoelectric encoder may be damaged due to interference. Check whether there is a strong
magnetic/heavy current circuit. If yes, isolate the circuit as much as possible.
III. The servo motor jitters.
a. Confirm whether the load and inertia of the servo motor is within the permissible range of the motor.
b. Adjust Parameters PA-5, PA-6, PA-7, PA-8, PA-9, PA-10, and PA-11.
c. Add or reduce parameters according to the jitter conditions when the motor is running with high speed
and low speed.
IV.
The servo motor gives out noise.
a. Confirm whether the load and inertia of the servo motor is within the permissible range of the motor.
b. Adjust Parameters PA-5, PA-6, PA-7, PA-8, PA-9, PA-10, and PA-11.
c.
Add or reduce parameters according to the noise given out by the motor when the motor is running with
high speed and low speed and stops.
V.
Setting of electronic gear ratio
Take the NC machine as an example:
a. The servo motor is directly connected with the lead screw (The lead screw rotates for one revolution
when the motor rotates one revolution).
●
If the numerical control system programming is 10 mm, then sent out 10000 pulse
●
The photoelectric encoder has 2500 wires.
● The pitch of the lead screw is 6mm.
