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 when the
number of motor rotations is stopped
immediately. 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.
Wire the encoder correctly as shown

The change in position command is
too large.
Reduce the electronic gear ratio. Adjust the electronic gear ratio so that
the changes in the position command
are not too large.
The backlash compensation amount
is too large.
Reduce the backlash compensation
