Chapter 9 Troubleshooting
Encoder
multi-turn count
overflow
The multi-turn count
exceeds 65535.
Check whether P11.33
exceeds the maximum
number of encoder turns.
Use the speed change mode to run
the motor to stagger the multi-turn
overflow position or shield the
multi-turn overflow fault.
Position deviation
is too large
The position deviation
exceeds the set value of
P05.21.
Check whether the
position deviation
detection range P05.21 is
too small or whether the
position gain P08.02 is
too small.
Increase the position loop gain
P08.02.
The pulse frequency
exceeds the value set by
P10.13.
Confirm whether the
maximum position pulse
frequency P10.13 is too
small
Set P10.13 again according to the
maximum position pulse frequency
required for the normal operation of
the machine.
If the output pulse frequency of the
upper computer is greater than
4MHz, the output pulse frequency of
the upper computer must be
reduced.
CAN bus
communication
connection
interrupted
The communication
between the CAN master
station and the servo is
interrupted for more than
the time of P16.03.
Confirm the wiring
between the CAN master
and the servo.
Rewire or set the appropriate
disconnection detection time
P16.03 according to the
communication cycle.
After the homing is
enabled, the home is not
found within the time of
P12.09.
Confirm the homing
mode and the homing
timeout detection time
P12.09.
Set an appropriate homing
timeout detection time according to
the homing path.
When P10.04=0, it
exceeds the positive limit
switch during running.
Check whether
mechanical equipment
encounters limit switch.
Run the motor in reverse to get the
device off the limit switch.
When P10.04=0, it
exceeds the negative
limit switch during
running.
Check whether
mechanical equipment
encounters limit switch.
Run the motor in reverse to get the
device off the limit switch.
External fault terminal
action.
Check whether the fault
terminal is triggered by
mistake.
