fast. For example, if the override is set to 50%, the travel speed drops to half
the maximum feed rate.
The acceleration remains constant even if the speed is changed by using the
override function. As a result, both the acceleration time and the deceleration
time are proportionally reduced.
Override in CP Control In interpolation control, the designated interpolation feed rate is used as the
maximum feed rate. The override for the interpolation feed rate can be set to a
value between 0.1% and 199.9%. If the result set by using the override func-
tion to over 100% exceeds the maximum interpolation feed rate, the maximum
interpolation feed rate is used instead.
Example: Execution in Stop Mode
Note With linear or circular interpolation in either the Pass Mode or the In-position
Check OFF Mode, the speed cannot be changed in real time during operation.
Setting an Override To execute an override, set the override in the PLC Interface Area and turn
ON the Override Setting Bit. The override will then be applied to subsequent
operations.
PLC Interface Area
Even if an override is set for a given axis, it will be disabled if the Override Set-
ting Bit is turned OFF.
