Troubleshooting
Solution
software limit position settings
P11.63 and P11.64 are proper.
Check whether the feedback
from the position sensor is
proper.
Check whether the maximum
software limit position settings
P11.61 and P11.62 are proper.
Check whether there are any
exceptions in the
operation of the
mechanism.
Solution
Check the input power and
wiring.
Check whether the
highest position point has been
reached.
Check the input terminal signal.
Check whether the
lowest position point has been
reached.
Check the input terminal signal.
Check whether the
protection point is too high.
Check whether the grid voltage
or rectifier module is abnormal.
Check whether the load is too
large.
