STOP input You can stop the processing of the current NC record via the
STOP input. If a positioning task is running at that moment, it
will be interrupted. The current positions become the nom
inal positions (closed−loop controlled stop).
The stop status is cancelled by:
1. a 1−signal at the STOP input.
2. renewed start
of the sequence, e.g. by a rising edge at
the ST AR T input.
START input Using the start input, you can start the selected starting pro
gram, or resume the current program after a stop, or set the
current program back to the initial state, or acknowledge a
fault message; for details see chapter 5.
The START input is edge−triggered, and responds exclusively
to the level change from 0−signal to 1−signal.
READY output This output supplies a 1−signal if the system is ready to oper
ate. A 0−signal at this output indicates that the SPC200 is not
yet ready to operate, because:
 there is a system fault or positioning
fault
 the enable signal is missing or
 the rising signal edge required at the ENABLE input for
the first commissioning, after a Data Reset or after the
movement test, is missing (e.g. the ENABLE input is incor
rectly connected to the supply voltage).
