K-Cube Inertia Piezo Motor Driver
Jogs
These parameters define the speed and acceleration of moves by jog command,
either from the joystick, GUI panel or via software.
Jog Mode
- The way in which the motor moves when a jog command is received (i.e.
front panel 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 distance specified in the Step Size parameter.
The jog key must be released and pressed again for jogging to be repeated - see Fig.
6.3. In ‘Continuous’ mode, the motor actuator will accelerate at the Step Accn value
and move at the Step Rate while the button is held down..

Jog Step Size
- The distance to move when a jog command is initiated. The step size
is specified by the ‘number of steps’ (or pulses)’, in a jog step, in the range 1 to 2,000.
The optimum step size depends on several parameters including the resistive torque
against which the actuator tip is pushing, the drive voltage, the step rate, active
preload, variance in the frictional behaviour of assembly components, the direction of
actuation and the condition of the actuator.
Step Rate
- The velocity to move when a jog command is initiated. The step rate is
specified in pulses per second, in the range 1 to 2,000.
Step Accn
- The acceleration up to the step rate. It is specified in pulses/sec/sec in
the range 1 to 100,000.
Persist Settings to Hardware -
Many of the parameters that can be set for the Inertial
Driver K-Cube 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
