deflection is increased. Bidirectional control of motor moves is possible by moving the
wheel in both directions.
Joystick Mode
Velocity Control - Deflecting the wheel starts a move with the velocity proportional
to the deflection. The maximum velocity (i.e. velocity corresponding to the full
deflection of the joystick wheel) and acceleration are set in the Max Velocity and
Acceleration. parameters.
Jog - Deflecting the wheel initiates a jog move, using the parameters specified by
the Move/Jogs tab. Keeping the wheel deflected repeats the move automatically
after the current move has completed.
Move To Position - Deflecting the wheel starts a move from the current position to
one of the two predefined "teach" positions. The teach positions are specified in
the Preset Position 1 and Preset Position 2 parameters, and are measured in
number of steps from the home position.
Joystick Direction
The direction of a move initiated by the velocity wheel is specified as follows:
Forwards - Upwards rotation of the wheel results in a positive motion (i.e.
increased position count).
Note. The following option applies only when the Wheel Mode is set to Velocity
Control. If set to Position Jogging or Go to Position Mode, the following option is
ignored.
Backwards - Upwards rotation of the wheel results in a negative motion (i.e.
decreased position count).
MMI Display
In certain applications, it may be necessary to adjust the brightness of the LED display
on the top of the unit. The brightness is set in the Display Intensity parameter, as a
value from 0 (Off) to 100 (brightest). The display can be turned off completely by
entering a setting of zero, however, pressing the MENU button on the top panel will
temporarily illuminate the display at its lowest brightness setting to allow adjustments.
When the display returns to its default position display mode, it will turn off again.
Furthermore, 'Burn In' of the display can occur if it remains static for a long time. To
prevent this, the display is automatically dimmed after the time interval specified in the
Display Timeout parameter has elapsed. The time interval is specified in minutes in
the range 1 to 480. The dim level is set in the Dimmed Intensity parameter, as a
percentage of full brightness from 0 (Off) to 10 (brightest) but is also limited by the
Display Intensity parameter if this is lower. These settings are only visible and active
if the Dim device display on inactivity box is checked.
