The Display Positions status screen displays the current position of the four motor-
driven positioners. The positions are given in motor steps, counted from the home po-
sition of each axis. There are 24 steps per revolution for the Vertical (Y) Axis and In-
sertion (Z) Axis motors. There are 200 steps per revolution for the I/O port Axis and
Carousel (X) Axis motors.
•
IS
This value indicates the current I/O Port carrier position. A value of 0 means
that the I/O Port Slot is at its home position (fully retracted).
•
X
This value indicates the current Carousel position. A value of 0 means that the
Carousel is at its home position (face 1).
•
Y
This value indicates the current vertical position of the Carriage. A value of 0
means that the Carriage is at its home position (at the bottom of its travel
range).
•
Period Y
Used primarily for diagnostics, this value represents the period of time that it
takes for the Hall-Effect sensors in the Y-axis brushless DC motor to move be-
tween two points. The maximum value of 65,535 will be shown when the motor
is not moving.
•
Z
This value indicates the current position of the Handler's Gripper. A value of 0
means that the Handler's Gripper is in its home position (fully retracted).
•
Period Z
Used primarily for diagnostics, this value represents the period of time that it
takes for the Hall-Effect sensors in the Z-axis brushless DC motor to move be-
tween two points. The maximum value of 65,535 will be shown when the motor
is not moving.
