(3) Adjusting the in-position width
Because there is a response delay in the servomotor drive due to position loop control, a "settling
time" is also required for the motor to actually stop after the command speed from the CNC
reaches 0. The movement command in the next block is generally started after it is confirmed
that the machine has entered the "in-position width" range set for the machine.
Set the accuracy required of the machine for the in-position width. If an unnecessarily high
accuracy is set, the cycle time will increase due to a delay in the settling time.
The in-position width is effective even when the standard servo parameters are set. However, it
may follow the CNC parameters, so refer to the CNC Instruction Manual for the setting.
