7 AUXILIARY AND APPLIED FUNCTIONS
7.7 Override Ratio Setting Function
The speed change can be executed by setting the override ratio to the command
speed of the Motion program in this function.
[Control details]
(1) The override ratio is set in the range of 0 to 100[%] in 1[%] units to the command
speed in the Motion program. The value obtained by multiplying the command
speed by the override value is the real feed speed.
(2) The override ratio is set to each axis.
The default value is 100[%] in all axes.
[Data Setting]
(1) The speed change by the override ratio setting function is used the override ratio
setting register.
The override ratio setting register of each axis are shown below.

(2) The ratio is set to the override ratio setting register within the range of 0 to 100[%].
(3) When the override ratio enable/disable (M4405+10n) is ON, the content of
override ratio setting register is valid. When the M4405+10n is OFF, it is controlled
at the override ratio of 100[%].
[Cautions]
(1) When the SVST instruction is executed, the content of override ratio setting
register for the lowest starting axis valid.
[Example]
Axis 2, 3, 4 start instruction
SP.SVST
K100 M0 D0
H3E3
"J2J3J44"
• When the above SVST instruction is executed, the data of axis 2 is valid. (The
data of axis 3, 4 are invalid.)
