8.3 Override Function
When an axis is moving via rapid traverse or interpolation feed for example, the speed of move-
ment can be changed by setting a override percentage with respect to the specified speed.
• The procedure used to set override is different in rapid traverse and interpolation opera-
tions.
• An override in the range of 0% to 327.67% can be selected for the Rapid Traverse
Speed. Set Override (OW †† 2C) in the setting parameter for each axis.
• There are three override setting methods: Motion program, ladder logic program, or the
Parameter Setting Window.
• The override is always enabled during initial operation, but this can be changed from a
ladder program, motion program, or parameter settings while an axis is moving.
• A parameter setting error will be generated if the override data setting causes the output
speed to fall outside the acceptable range.
