5 Servo Adjustment
MITSUBISHI CNC
(3) Adjusting the in-position width
Because there is a response delay in the servo motor 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 precision required for the machine as the in-position width. If a high precision is set needlessly, the cycle
time will increase due to a delay in the settling time.
The in-position width is validated with the servo parameter settings, but there may be cases when it is validated with
the NC parameters. Refer to each NC Instruction Manual.
【#2224】 SV024 INP In-position detection width
Set the in-position detection width.
Set the positioning accuracy required for the machine.
The lower the setting is, the higher the positioning accuracy will be. However the cycle time (settling
time) becomes longer.
The standard setting value is "50".
---Setting range---
0 to 32767 (μm)
POINT
The in-position width setting and confirmation availability depend on the CNC parameters.
