Jogging the liquid-handling head

About this topic

Jogging the liquid-handling head moves it in small precise increments. You can jog the liquid-handling head in the x-axis, y-axis, z-axis, or w-axis.

Jogging is useful when setting teachpoints and performing maintenance activities.

 

To avoid potential injury and damage to the device, only personnel trained in how to teach the Bravo Platform should use the Jog/Teach tab controls.

 

 

To perform an emergency stop, press the red button on the emergency-stop pendant.

 

 

To prevent damage to the gripper and other hardware components, do not dock the gripper if you want to jog the liquid-handling head along the y-axis and z-axis.

 

 

Axes of motion

You can use the Jog/Teach tab controls to jog the Bravo head in the following four directions.

 

Axis	Description
X	The horizontal distance (left-to-right) in millimeters, along the rail from the x-axis home position.
Y	The horizontal distance (front-to-back), in millimeters, along the rail from the y-axis home position.
Z	The vertical distance, in millimeters, from the z-axis home position.
W	The vertical distance, in microliters, from the w-axis home position.

Jogging the liquid-handling head

 

Keep away from the Bravo Platform when the liquid-handling head is moving or about to move, especially in the z-axis direction. The head’s z-axis motor is particularly powerful. It might not stop immediately in a collision and a pipette tip could pierce your hand.

 

 

Before you jog the liquid-handling head, remove objects from its path. Move the head slowly and keep the jog increment small until you are certain that there is no obstruction.

 

To jog the liquid-handling head:

1	Open Diagnostics and click the Jog/Teach tab.

2	In the Jog Axes area, select the jog increments in the appropriate list.

 

3	Click a direction button to move the head.

4	Monitor the current position of the liquid-handling head by checking the W-Axis, X‑Axis, Y‑Axis, and Z‑Axis displays.

When the given axis is at the home position, a value of 0.00 displays.

When the liquid-handling head is not in the home position, the position is displayed as the distance from the home position for each axis.

Note: The teachpoint coordinates for the selected location are displayed under the Location list.
