■
Set to restrict Velocity command.
◆
Sets the maximum value of Velocity command.
◆
Restricts Velocity command at the setting range.
◆
At the setting value 5000 and over, Velocity command is restricted at maximum speed of
the combined motor x 1.1.
Set this parameter to limit motor rotational velocity to the value lower than 1.1 times the
maximum rotational velocity. Use the standard value for normal use.
