Editing Motion fault limit paremeter

The parameter called "motion fault limit" controls a safety faulting mechanism of GD servo drives.
==Usage==
Motion fault tries to detect incorrect motor behavior and sets drive in fault state if motion fault threshold exceeded. The motion fault will help to detect following fault scenarios:
* DC motor runaway when [[Feedback devices|feedback]] is lost
* Motion blocked by obstacle and axis stops (can react faster than following/tracking error fault)
* Detect stall of stepping motor
==How it works==
Motion fault monitors three variables to determine fault:
* Actual velocity
* Time
* Output torque/current

Drive activates fault if output current is greater than set threshold value for over 0.2 second period and simultaneously velocity stays below a fixed threshold.
==Parameters==
Motion fault has only one changeable parameter: threshold. The '''threshold''' value controls the current level which must be exceeded to activate 0.2 second timer and velocity monitor.
===Finding correct value===
Correct value can be found by experimenting. 
# Set threshold to low starting value such as 500
# Try settings 
* Once you have threshold that sometimes triggers, sometimes not, increase threshold by 30-50% to sta
