Stop and the Issue of an Alarm upon an Emergency Stop
NOTE
For this signal, the CNC monitors not only input from
the PMC to the NC but also the interface between the
machine and the PMC. This means that the interface
(connector pins) between the machine and PMC
cannot be changed.
An overtravel is detected with the stored stroke check function. To
prevent the machine from moving beyond a software limit if a servo
feedback system error occurs, set the stroke end limit switches as
shown in Fig. 2.1(c).
