Control precautions
• When the speed is changed using Override function during the continuous path control, the speed change is ignored and
Insufficient remaining distance (Warning code: 0995H) occurs if a distance enough to perform the speed change cannot be
ensured.
• During the deceleration by a stop command or during the automatic deceleration in the position control, Deceleration/stop
speed change (Warning code: 0990H) occurs and the speed cannot be changed using the override function. (The value set
in [Cd.13] Positioning operation speed override is validated after the deceleration stop.)
• To change the speed using the override function during the interpolation control, configure the required setting in the
reference axis.
• To change the speed successively using the override function, set 10ms or longer as the interval between each speed
change. (If the interval between the speed changes is short, the override value may not be reflected to the speed.)
• When the machine OPR is performed, the speed change using the override function cannot be performed after the start of
the deceleration to the creep speed following the detection of the near-point dog ON. In this case, the speed change
request is ignored.
• Deceleration start flag is not turned on when the deceleration is performed using the override function.
