The following table lists the differences between the embedded HSC and the
2080-MOT-HSC plug-in module.
Embedded HSC
Limited to 100 kHz
12/24V input
None
Dedicated preset and hold inputs
None
When using the 2080-MOT-HSC module, the high and low preset
IMPORTANT
status does not automatically reset. When using the embedded HSC,
it automatically resets when the high and low preset condition no
longer exists.
Filter and decode inputs: 3 input points A, B, Z
These input points may come from different types and configurations of sensors.
The user must configure the module to respond to the type of sensor connected
to the module as described below. This can be configured in the 2080-MOT-
HSC UDFB. From Connected Components Workbench Release 8.0 onwards, if
you have configured the plug-in for Feedback Axis, you can also edit the input
filter values in the plug-in configuration module properties.
