Possible causes Solutions
drive recalibrate the sine and
cosine AD coefficients
4. Restart the drive
5. Replace the drive
31.
Second encoder
communication
abnormal
0xFF11
1. There is a fault in the
encoder
2. The wiring of the motor
encoder is abnormal (such as
broken line)
3. The wiring of the motor
encoder is disturbed (for
example, the cable does not
use shielded twisted pair, or
is coupled with the power
cable of the motor, or the
ground wire of the drive is
not reliably connected, etc.)
4. There is strong interference
source around the drive
1. Replace the encoder
2. Check the wiring of the
motor encoder and make
sure that the wiring is
standard and correct
3. Add magnetic rings to the
cable of the encoder and the
power cable of the motor
4. Connect the ground wire of
the drive reliably
5. Remove the strong
interference source around
the drive, or power on the
drive separately from the
strong interference source
6. Add an incoming line filter
for the power supply input
of the drive
32.
Second encoder
communication timeout
0xFF12
1. There is a fault in the
encoder
2. The wiring of the motor
encoder is abnormal (such as
broken line)
1. Replace the encoder
2. Check the wiring of the
motor encoder and make
sure that the wiring is
standard and correct
33.
Second encoder internal
abnormal 1
0xFF13
The internal state of the encoder
is abnormal
1. Reset the encoder
2. Restart the drive
34.
Control encoder over
speed
0xFF14
1. The velocity tracing
overshoot is too large due to
the unreasonable settings of
the parameters of the drive
regulator
2. The data transmission of the
encoder is disturbed
3. The encoder is damaged
1. Optimize the parameters of
the regulator to improve the
velocity tracing performance
2. Enhance the
anti-interference measures
for the cable of the encoder,
for example, by adding
magnetic ring, using shielded
twisted pair, conducting
reliable grounding, and so on
3. Replace the encoder
