Signal description
6.3.1
Common signals
The following signals are for the external axes 7 -12:
LIM SW EXT(l-7)
The signal is common to all limit-position switches throughout the system. All limit-switches
are connected in series. An open circuit indicates that the external axis has reached the limit
of its working range, and this will tripthe safety chains in the robot. The signal must be
jumpered if not used. When the MOTOR ON-button in the control system is kept depressed,
the axis can be jogged past the limit-position switches back into working range.
Note: The dual safety chains requries on intermediate relay if a single limit switch is used.
