Functions
If you want to use both the CSS I/O and the KT 130 edge finder at the
same time, or if you want to transmit measured values via the external
switching output, the distribution cable with ID 593761-01 is required.
Switching inputs
The CSS I/O provides four inputs that are used to zero the actual value
of the assigned axis. A low-to-high transition at the input causes the
value for that axis to be set to zero.
Switching outputs
The switching outputs consist of integrated relays available for generic
usage. The number of switching outputs available is dependent on the
configuration options chosen. When the system is configured for a
Mill, and the spindle speed control (RPM) is disabled, 8 switching
outputs are available. If RPM is enabled, then only 5 switching outputs
are available. See "Spindle Speed Control (RPM)" on page 8.
When the system is configured for a Lathe, and the constant surface
speed (CSS) is disabled, 8 switching outputs are available. If CSS is
enabled, then only 5 switching outputs are available. See "Controlling
the Constant Surface Speed (CSS)" on page 14.
The switching outputs are activated depending on “position”. The
relays can be configured to activate when a position display reaches a
specific value, or within a specified range of zero. The ninth output
relay indicates readiness.
Select SWITCHING OUTPUTS from the INSTALLATION SETUP menu
to open the SWITCHING OUTPUTS table in which the configuration of
the outputs are stored. If you want to change the configuration of an
output, select it with the arrow keys, and press ENTER to confirm your
selection. This opens the OUTPUT SETTINGS form in which you
define the switching conditions. To reset a relay, select the relay in the
table and press the CLEAR RELAY soft key, followed by the YES soft
key for confirmation.
