System installation
Arm control
Two separate machine
tool control outputs are
required to command
the arm to move to
“machine ready position”
(MRC) and “arm ready
position” (ARC). The
user must ensure that
both outputs are never
active at the same
time. There must be a
minimum time delay of
0.1 seconds (100 ms)
between one command
being de-activated
and the other being
activated. If both outputs
are active at the same
time then the arm is
unable to determine
what to do and will
stop. This condition
can only be overcome
by de-activating both
outputs.
Two machine tool control
inputs are required to
receive arm position
confirmation signals for
“machine ready” (MRO)
and “arm ready” (ARO).
All I/O are “ACTIVE HIGH” configuration.
