Fig. 6.2 Piezo Motor Driver T-Cube - Move/Jog Settings
Moves can be initiated via the GUI panel, either by using the jog buttons (see Section
5.6.) or by entering a position value after clicking on the position display box (see
Section 5.3.), or by pressing the buttons on the unit.
Moves - Drive Output Params
These parameters define the speed and acceleration of moves initiated by clicking in
the position display, or via the buttons when 'Go To Position' mode is selected.
Peak Voltage - the maximum piezo drive voltage. Set in the range 85V to 125V.
Step Rate - The piezo motor moves by ramping up the drive voltage to the value set
in the Peak Voltage parameter and then dropping quickly to zero, then repeating (see
Fig. 6.3). One cycle is termed a step. The Step Rate is the velocity to move when a
command is initiated. It is specified in steps/sec, in the range 1 to 2,000.
Step Accn - The acceleration up to the step rate. It is specified in steps/sec/sec in the
range 1 to 100,000.
Note
The step size is defined as the distance moved in one step or pulse. This
distance can be adjusted up to about 30% by changing the piezo drive
voltage. The actual step size achieved for a given drive voltage will be
dependant on application.
