(2) When the speed is changed by the override ratio setting function,
acceleration/deceleration processing is executed according to the "acceleration
time" and "deceleration time" in the parameter block.
(3) The override ratio setting is valid for Motion program operation only. (Invalid for
JOG operation and so on.)
(4) The error contents for override ratio data setting are shown below.

At a start, the value set in the override ratio
setting register is except 0 to 100[%].
290
During operation, the value set in the override
ratio setting register is except 0 to 100[%].
• Operation is performed at 100[%].
(Operation is executed at
command speed in the Motion
program.)
Sets the override
ratio within the
range of 0 to 100
[%].
