Possible causes
Solutions
function can be disabled via
the parameter 0x20A1.Byte0
38.
Motor stalling
0xFF18
1.
The
velocity
tracing
overshoot is too large due to
the unreasonable settings of
the parameters of the drive
regulator
2.
The
set
value
of
the
parameter 0x20A0 is too
small
3.
The wiring of the encoder is
poor
4.
The data transmission of the
encoder is disturbed
5.
The encoder is damaged
6.
The internal circuit of the
drive is abnormal
1.
Optimize the parameters of
the regulator to improve the
velocity tracing performance
2.
Properly increase the set
value of the parameter
0x20A0
3.
Check the wiring of the
encoder cable and make
sure that the wiring is
reliable
4.
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
5.
Replace the encoder
6.
Replace the drive
39.
Co-CPU
communication
abnormal
0xFF19
1.
The ground wire of the drive
is not reliably connected
2.
There is strong interference
source around the drive
1.
Add magnetic rings to the
cable of the encoder and the
power cable of the motor
2.
Connect the ground wire of
the drive reliably
3.
Remove
the
strong
interference source around
the drive, or power on the
drive separately from the
strong interference source
4.
Add an incoming line filter
for the power supply input
of the drive
40.
Encoder
AB
signal
change abnormal
0xFF20
1.
The wiring of the motor
encoder is abnormal (such as
broken line, cold solder joint)
2.
The encoder line is disturbed
1.
Check the wiring of the
motor encoder and make
sure that the wiring is
standard and correct
2.
Add magnetic rings to the
cable of the encoder and the
