Common faults and solutions
|
|
The normal state is that the green light is always on and the red light is always off. When it is abnormal, the red light flashes or the red and green lights flash alternately.

Approach
|
|
1
|
Hardware accelerated overcurrent
|
Red light flashes once |
Acceleration and deceleration too fast
|
Increase acceleration and deceleration time
|
|
2
|
Hardware deceleration overcurrent
|
Red light flashes 2 times |
Low voltage
|
Check whether the input voltage matches
|
|
3
|
Hardware constant speed overcurrent
|
Red light flashes 3 times |
Drive power is too small
|
Choose a high-power drive
|
|
4
|
Software accelerated overcurrent
|
Red light flashes 4 times |
Burst load
|
Check whether the load is normal
|
|
5
|
Software deceleration overcurrent
|
Red light flashes 5 times |
Short circuit between phases
|
Check and replace the cable or motor
|
|
6
|
Software constant speed overcurrent
|
Red light flashes 6 times
|
There is a strong external source of interference
|
Check whether there is a strong interference source
|
|
7
|
Overpressure during acceleration
|
Green light flashes once and red 2 times |
Input voltage is too high
|
Check the power supply voltage
|
|
8
|
Overvoltage during deceleration
|
Green light flashes once and red 3 times |
Fast forward and reverse switching
|
Increased division forward and reverse switching time
|
|
9
|
Overvoltage at constant speed
|
Green light flashes once and red 4 times |
Being dragged by external force, in a state of generating electricity
|
Add external braking device
|
|
10
|
Bus undervoltage fault
|
Green light flashes once and red 5 times |
1. Low power supply voltage
2. Accelerate too fast, external power supply protection
3. The supply voltage drops
4. Drive hardware abnormality
|
1. Check the power input
2. Increase acceleration time
3. Fault reset
4. Check whether the hardware is normally powered on
|
|
11
|
Motor overload
|
Green light flashes 2 times, red 1 time |
1. The power supply voltage is too low
2. Motor power is too large
3. Motor stalls or sudden load changes
|
1. Check the power input
2. Set the rated current of the motor
3. Reduce the load detection motor
|
|
12
|
Drive overload
|
Green light flashes 2 times, red 2 times |
1. The power supply voltage is too low
2. Acceleration time is too fast
3. Excessive load
|
1. Check the power input
2. Increase acceleration time
3. Replace the first gear controller
|
|
13
|
Hall failure
|
Green light flashes 2 times, red 3 times |
1. Hall disconnection
2. There is a strong source of external interference
|
1. Check whether the Hall connection line is abnormal
2. Detect whether there is a strong interference source
|
|
14
|
Stall failure
|
Green light flashes 2 times, red 4 times |
1. Excessive load
2. The motor is stuck
|
1. Check whether the load changes
2. Detect the mechanical connection of the motor
|
|
15
|
Current detection failure
|
Green light flashes 3 times, red 4 times |
Drive hardware is damaged
|
Replace the driver
|
|
16
|
Parameter storage failure
|
Green light flashes 5 times, red 2 times |
Reach the number of erasing and writing at a single power-on
|
Power on again
|
|
17
|
Overcurrent feedback fault
|
Green light flashes 5 times, red 4 times |
Drive hardware is damaged
|
Replace the drive
|
|
18
|
Output phase failure
|
Green light flashes 5 times, red 5 times
|
1. U/V/W output phase loss
2. The drive hardware is damaged
|
1. Check whether the U/V/W is connected firmly 2. Replace the drive
|
