Weightless calibration procedure continued
When performing a calibration, both the zero and WEIGHTLESS
calibrate steps must be done in sequence before a calibration
is valid.
If only zeroing the tension is required, use the 0x1E or 0x1F
command.
1.
Unload the load cell(s) for Tension Zone 1.
2.
Enter the command 0x01 (Zero Calibrate Zone 1) in the
Command Request.
The DLCA NET-ECAT immediately
responds with 0x8000 0001 (Busy) in the
Command
Response
.
If the calibrate zero is successful, the DLCA NET-ECAT will
respond after ten to twenty seconds with 0x1000 0001.
Otherwise, error message 0x20XX 0001 will be returned.
3.
Clear the
Command Request
by entering the command
0x00.
4.
Enter the command 0x03 (Weightless Calibrate Zone 1) in
the
Command Request
. The DLCA NET-ECAT will
immediately respond with success message 0x1000 0003
or
error message 0x20XX 0003 in the
Command Response
.
5.
Clear the
Command Request
register by entering the
command 0x00.
Clearing the command request is necessary to prevent
starting multiple calibrations, such as zero and precision,
before the first entered request is finished.
Weightless Calibration is complete.
Note:
If the returned tension values in the cyclic data are negative
you will need to manually set the
Tension Polarity
parameter
(0x216 or 0x223) so the tension values are positive.
