Lock Tolerance
Type a value, in position units, representing the maximum servo axis
position error the controller will tolerate when indicating axis locked
status.
Note: The controller interprets this value as a ± measurement around
the axis position.
Backlash
Backlash is the relative movement between interacting mechanical parts
due to looseness. Commander provides the means to set a compensation
type and offset value to counter any looseness in your servo system.
Compensation
If your servo system contains slop (i.e. inaccuracy between commanded
and actual position due to loose mechanical connections), you can
compensate for this slop by selecting a backlash compensation type. the
available types are:
•
Positive Approach
•
Negative Approach
•
Load Reversal
