1. 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.
2. The motor runs faster in one direction than in 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) Cause of failure: The position of the deviation potentiometer is incorrect.
Solution: Reset.
3. The motor stalls;
(1) Cause of failure: The polarity of the speed feedback is wrong.
Solution: You can try the following methods.
a. If possible, turn the position feedback polarity switch to another position. (Yes on some drives)
b. If using a tachometer, switch the TACH+ and TACH- on the drive.
c. If an encoder is used, switch ENC A and ENC B on the drive.
d. 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 the voltage is signaled to ground for the driver.
4. 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 directed to the driver.
Solution: Connect the command signal ground to the drive signal ground.
5. 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.
6. When the motor rotates, the LED light flashes;
(1) Cause of failure: HALL phase error.
Solution: Check whether the motor phase setting switch (60°/120°) is correct. Most brushless motors are 120° apart.
(2) Cause of failure: HALL sensor failure
Solution: Detect the voltage of Hall A, Hall B, and Hall C when the motor is rotating. The voltage value should be between 5VDC and 0.
7. The LED light is always kept red;
Fault Cause: A fault exists.
Solution: Cause: Overvoltage, Undervoltage, Short Circuit, Overheating, Driver Disabled, HALL Invalid.
