10-6 Changing Speed Using an Override during Pulse Output
Overview
• Override can be used to change the speed during pulse output.
• The target speed is determined by the override coefficient set in the oper-
ating data area.
• In order to use the actual target speed that has been set, either disable
the override or set it to 100%.
Operation Example
The following is an example of changing the speed with override during con-
tinuous operation.
1,2,3... 1. When the operation start switch is turned ON, pulse output is executed at
a speed of 300 pps CW on the X axis.
2. When speed change switch 1 is turned ON, the pulse output decelerates
to a speed of 150 pps.
3. When speed change switch 2 is turned ON, the pulse output accelerates
to a speed of 500 pps.
