Possible causes
Solutions
motor is too low
7.
The power cable of a phase
of the motor is not reliably
connected
to ensure that they are set
correctly (e.g. rated current
of the motor, instantaneous
overload
protection
threshold of the motor,
instantaneous
overload
protection duration of the
motor)
7.
Replace the motor with a
high-power one
8.
Replace the drive
9.
Check the wiring of the
motor's power line for
reliable connection
68.
Dynamic
brake
overload
0xFF48
The time interval between two
consecutive
dynamic
braking
stops is too short
Ensure that the interval between
two dynamic braking stops is
greater than the set value of
0x21D3
69.
Drive internal abnormal
0xFF49
The drive failed the factory test
Replace the drive
70.
Hardware limit switch
abnormal
0xFF50
1.
When the motor is running
positive, it is detected that
the negative limit switch is
triggered
2.
When the motor is running
in negative direction, it is
detected that the positive
limit switch is triggered
Check the wiring and parameter
settings to ensure that the
polarity definition and wiring of
the limit switches are correct
71.
EtherCAT
communication
abnormal
0xFF51
1.
The
EtherCAT
communication is disrupted
2.
The
EtherCAT
cable
is
disconnected or not reliably
connected
3.
The upper computer is not
real-time enough
4.
The
underlying
DC
synchronization mechanism
of the upper computer
EtherCAT
master
station
does
not
meet
the
requirements of the drive
1.
Optimize the wiring of the
EtherCAT
communication
and
enhance
the
anti-interference measures,
for example, by using CAT6
shielded network cable and
ensuring reliable grounding
of the controller
2.
Check the connections of the
EtherCAT cables to ensure
that they are reliable
3.
Replace the upper computer
with a more real-time one,
