Prevention
The velocity command value is
too large
Do not give the excessive velocity
command. Check whether the
electronic gear ratio is set cor-
rectly.
Set the velocity command value
within the range in which the feed-
back motor velocity does not
exceed the excess velocity detec-
tion level.
Overshooting occurred
If overshooting occurred due to
faulty gain adjustment, adjust the
gain.
Do not increase the gain too much.
The motor is rotated by external
