LTS Series Long Travel Stages
Jogs
Jogs are initiated by using the ‘Jog’ keys on the GUI panel (see Section 6.7.), or via
the buttons on the control key pad.
Velocity Profile
- specified in real world units, (millimetres)
Note.
In current versions of software the ‘Min Vel’ parameter is locked at zero and
cannot be adjusted.
Max Vel
- the maximum velocity at which to perform a jog
Accn/Dec
- the rate at which the velocity climbs from minimum to maximum, and
slows from maximum to minimum.
Operating Modes
Jogging
- The way in which the motor moves when a jog command is received (i.e.
handset button pressed or 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. If the jog key is held down, single step jogging is repeated until the button
is released - see Fig. 7.3. In ‘Continuous’ mode, the motor actuator will accelerate and
move at the jog velocity while the button is held down..
Fig. 7.3 Jog Modes
Note
The max velocity and acceleration values quoted opposite are achievable with
lighter loads. As the load is increased, the velocity and acceleration should be
decreased accordingly. For the maximum 15 kg load, the velocity should be reduced
to either 15 mm/s with 3 mm/s
2
acceleration or 12 mm/sec with 5 mm/s
2
acceleration, depending upon whether speed or acceleration is more important for
the intended application.
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).
Caution
When the stage is mounted vertically, the Max Vel parameter must be set to 3
mm/sec. and the Max Accn parameter to 5 mm/sec
