1. When the motor rotates, the LED light flashes
(1) Cause of failure: HALL phase error. Solution: Check whether the motor phase setting switch is correct
(2) Cause of failure: HALL sensor failure, treatment method: When the motor rotates, detect the voltage of HalA, HalB, HalC, and the voltage value should be in 5VDC and O
Between.
2. The LED light is green, but the motor does not move
(1) Cause of failure: The motor in one or more directions is prohibited from operating. Solution: Check the +INHIBIT and -INHIBIT ports.
(2) Cause of failure: The command signal is not to the driver signal. Solution: Connect the command signal ground to the drive signal ground.
3. The LED light is always kept red
Fault causes: overvoltage, undervoltage, short circuit, overheating, drive prohibition, HALL invalid and other faults. Solution: 1 - Check and find out the fault location, and then repair.
4. After powering on, the LED light of the driver does not light up
Cause of failure: The power supply voltage is too low, less than the minimum voltage value requirement. Solution: Check and increase the supply voltage
5. The motor runs faster in one direction than the other
(1) Cause of failure: The phase of the brushless motor is wrong. Solution: Detect or detect the correct phase
(2) Cause of failure: When not used for testing, the test/deviation switch hits the test position. Solution: Put the test/deviation switch at the deviation position (3) Fault reason: The position of the deviation potentiometer is incorrect. Solution: Reset.
6. The motor stalls
(1) Cause of failure: The polarity of the speed feedback is wrong. Solution: If possible, hit the position feedback polarity switch to another position, such as using a speed tester, and connect the TACH+ and TACH- on the drive; If an encoder is used, the ENCA and ENCB on the drive are switched to the connection; For example, in HALL speed mode, switch HALL-1 and HALL-3 on the drive, and then switch Motor-A and Motor-B.
(2) Cause of failure: When the encoder speed feedback, the encoder power supply loses power. Solution: Check that the 5V encoder power supply is connected. Make sure that the power supply can provide enough current. If using an external power supply, make sure that this voltage is for the driver signal.
7. When the oscilloscope checks the current monitoring output of the driver, it is found that it is all noise and cannot be read
Cause of failure: The current monitoring output is not isolated from the AC power supply (transformer). Solution: It can be detected and observed with a DC voltmeter
8. When the servo motor rotates at high speed, there is a motor deviation counter overflow error
(1) Cause of failure: motor deviation counter overflow error occurs when rotating at high speed. Solution: Check whether the wiring of the motor power cable and encoder cable is correct, and whether the cable is damaged
(2) Cause of failure: Motor deviation counter overflow error occurs when long instruction pulse is input. Solution: If the gain setting is too large, manually adjust the gain or use the automatic adjustment gain function to extend the acceleration and deceleration time, the load is too heavy, and it is necessary to re-select a motor with a larger capacity or reduce the load, and install a reducer and other transmission mechanisms to improve the load capacity.
(3) Cause of failure: motor deviation counter overflow error occurs during operation. Solution: Increase the overflow level set value of the deviation counter, slow down the rotation speed, prolong the acceleration and deceleration time, the load is too heavy, it is necessary to re-select a larger capacity motor or reduce the load, and install a reducer and other transmission mechanisms to improve the load capacity.
