Cause and
correction
Assumed cause Remedy Prevention
The velocity command value is too
large.
Reduce the velocity. Adjust the input
frequency, dividing ratio, and
multiplication ratio of the command
pulse.
Set the velocity command value in a
range that does not exceed the
overspeed detection level at
immediate stop. Check the input
frequency, dividing ratio, and
multiplication ratio of the command
pulse.
There is overshooting. Adjust the gain. Do not make the gain too large.
The wiring is incorrect. Wire the encoder correctly as shown
in the wiring diagram.
