listTI - list the Galil Box input assignments
SYNOPSIS
listTI
DESCRIPTION
This command will return the current state of the Galil
Box input assignments in a human readable way. The
DMC-1580 has 24 digital inputs for controlling motion by
local switches.
Inputs 1, 2 and 4 are used with the latching function
(high speed position capture) of the controller in the
homing routine of the stages. The latching function is
used to arm the position latches and capture the encoder
position upon a low going signal.
Input 3 is use as an interrupt signal that checks the
orthogonal condition of the stages (1 degree). Upon a low
signal the interrupt will caused the embedded software to
stop all motion in the system.
Input 5 is used as the master fault interrupt. Upon a low
signal this interrupt will cause the system to stop all
motions, halt all running processes and inhibit future
motions. The only way to clear a master fault condition is
to either cycle the power or lower the FSA (Focal Surface
Assembly) and manually toggle the Reset switch.
A master fault interrupt is activated whenever the third
orthogonal limit is hit, one of the XYW panic reverse/for-
ward limit is hit, or one of the panic switches is hit.
Input 6 is used to sense if the gripper is closed (0).
Input 7 senses if the gripper is opened wide. Input 8
senses button presence (0=empty).
Input 9 is used to sense the state of the plate (1 =
warp).
Input 13 senses the AC Drive Power condition. A high sig-
nal tells us that the drive power is on.
Input 17, 18, 19 and 20 connects the brushless servo
amplifiers fault output pin to the controller. The fault
output of the amplifiers indicates the status of the power
stage (amplifier enabled or disabled). The fault output
will go to its active state upon a power stage fault,
thermal overload, RMS current limit, power supply under
voltage condition, and DC bus over voltage condition (BA
Series USER'S Manual).
second orthogonal switch and to the FSA interlocks. Upon a
low signal motion is inhibited.
