Calibrate tension through the fieldbus procedure
The DLCA NET-ECAT has two modes of calibration: Precision and
Weightless. Precision calibration is used when applying a known
weight with a rope in the web path to the load cells for
calibration. Typically this known weight should be 10% of the load
cell rating or greater. Weightless calibration is used when a
known weight is not convenient or desired.
The
Command Interface
is used to perform the calibrations.
A command request is entered in the
Command Request
. The
Command Response
will show the progress of the command and
when the command is complete. Errors will also be shown.
Parameters for Tension Zone 1 can be accessed in the group
Configuration Tension 1
and those for Tension Zone 2 can be
accessed in the group
Configuration Tension 2
.
