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
- th e motor stops in a profile d 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).
Backlash Correction
- Backla sh is a te rm used to d escribe the errors inh erent in
motors which use a leadscrew. Brushless linear DC motors that have no leadscrew
and therefore this parameter is normally set to 0.
For motors which do incorporate a leadscrew, when this parameter is set, the system
will overshoot the demanded set point by the specified amount, and then reverse.
This ensures that durin g absolute or rel ative moves, the target position is alwa ys
approached in a forward direction. The Backlash Correction Distance is specified in
real world units (millimeters).
To remove backlash correction, this value should be set to zero.
Note. Setting a negative value for backlash correction also results in zero correction.
Persist Settings to Hardware -
Many of the parameters that can be set for the RBD201
series drivers 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 via a joystick, in the absence of a
PC and USB link. The
Move and Jog
parameters described previously are good
examples of settings that can be altered and then persisted in the driver for later use.
To save the settings to hardware, check the ‘Persist Settings to Hardware’ checkbox
before clicking the ‘OK button.
