Stopping - the way in which the jog motion stops when the demand is removed.
Immediate - the motor stops quickly, in a non-profiled manner
Profiled - the motor stops in a profiled manner using the jog Velocity Profile
parameters set above.
Step Distance - The distance to move when a jog command is initiated. The step
size is specified in real world units (mm or degrees dependent upon the stage).
Backlash Correction - The system compensates for lead screw backlash during
reverse direction moves, by moving passed the demanded position by a specified
amount, and then reversing. This ensures that positions are always approached in a
forward direction. The Backlash Correction Distance is specified in real world units
(millimeters or degrees). To remove backlash correction, this value should be set to
zero.
Persist Settings to Hardware - Many of the parameters that can be set for the
OptoDCDriver can be stored (persisted) within the unit itself, such that when the unit
is next powered up these settings are applied automatically. This is particularly
important when the driver is being used manually in the absence of a PC and USB
link. The velocity profiles and jogging parameters described previously are good
examples of settings that can be altered and then persisted in the driver for use in
absence of a PC. To save the settings to hardware, check the ‘Persist Settings to
Hardware’ checkbox before clicking the ‘OK button.
