Jogs
Note
. All jog moves are performed using either a trapezoidal or an S-curve profile,
depending on which mode is selected in the ‘Advanced-Misc. Tab - see Section 5.3.4.
Jogs are initiated by using the ‘Jog’ buttons on the GUI panel (see Section 4.6.).
Velocity Profile
(specified in real world units, i.e. mm or degrees).
MaxVel
- the maximum velocity at which to perform a jog.
Accn/Dec
- the rate at which the velocity climbs from zero to maximum, and slows
from maximum to zero.
Operating Modes
Jogging
- The way in which the motor moves when a jog command is received (i.e.
GUI panel button clicked).
There are two jogging modes available, ‘Single Step’ and ‘Continuous’. In ‘Single
Step’ mode, the motor moves by the step size specified in the Step Distance
parameter, each time the jog key is pressed - see Fig. 5.3. In ‘Continuous’ mode, the
Note
Under certain velocity parameter and move distance conditions, the
maximum velocity may never be reached (i.e. the move comprises an
acceleration and deceleration phase only).
The limits for the max velocity or acceleration parameters are dependent
on the stage being driven. They can be obtained by calling the
GetVelParamLimits
method.
The move is also affected by the ‘Profile’ and ‘Jerk’ settings in the
Advanced - Misc. tab.
