The axis movement can be set by EXE-service-axis parameter settings.
But why do you like to limit the movement? The error may be due to dried grease in the slides, rusty slides. Have you tried to clean the slides using wd-40 throughly and apply very light grease before starting?
When you turn the motor pulley, is the movement is smooth?
I believe you are getting movement fault. the main reason is some jerk in the movement.
Please update how you fix the issue.
