Prevention
Set the velocity command value in a
range that does not exceed the
overspeed detection level when the
number of motor rotations is stopped
immediately. Check the input
frequency, dividing ratio, and
multiplication ratio of the command
pulse.
Do not make the gain too large.
Wire the encoder correctly as shown
in the wiring diagram.
