Omron servo drive repair, quickly fix drive power-on errors

   Omron servo drive maintenance faults; inverter and servo drive faults mainly include no display, phase loss, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, display but no output, module damage, and error. The screen has no display, the screen does not light up, black screen, blue screen, blurry screen, etc.

Omron servo driver, the input filter adjustment function can use the input filter to flatten the input. Measure the 6 pins of pc923 from x000 to The positive voltage is about 4v. The fault is a short circuit of q11 that drives the IC post-amplifier . Replace 6. This function is only valid after the external thermal relay is selected in the pr.60 to pr.63 settings. Inverter manual, inverter fault code, frequency converter machine failure,

Omron servo driver failure symptoms and solutions:

1. The LED light is green, but the motor does not move.

(1) Cause of the fault: The motor in one or more directions is prohibited from operating.

Solution: Check the +INHIBIT and –INHIBIT ports.

(2) Cause of the fault: The command signal is not connected to the driver signal ground.

Solution: Connect the command signal ground to the driver signal ground.

2. After powering on, the driver’s LED light does not light up.

Cause of failure: The power supply voltage is too low, less than the minimum voltage requirement.

Solution: Check and increase the power supply voltage.

3. 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.

4. The LED light always remains red

Cause of failure: There is a fault.

Solution: Cause: overvoltage, undervoltage, short circuit, overheating, driver disabled, HALL invalid.

5. Motor stalls

(1) Cause of the fault: The polarity of the speed feedback is wrong.

(2) Cause of failure: HALL sensor failure.

Solution: Detect the voltages of Hall A, Hall B, and Hall C when the motor rotates. The voltage value should be between 5VDC and 0.
