External Single Ended Shaft Encoder Setup
Tools required: Metric ruler.
To setup an external single ended shaft encoder to measure the speed of the production line:
(1) Create a test label.
(2) Select the
Label
tab in the label creator side menu and select
Settings
.
(3) Scroll down to the
Width
setting and make a note of the value.
(4) Select the
icon to send the label to print.
(5) Select
Home
>
Production line setup > Line movement
.
(6) Select the
Encoder input
drop down setting and select
External
.
(7) Scroll to the bottom of the
Line movement
menu, select the
Encoder mode
setting and
select
Single mode
.
(8) Select
Set
calibration settings
.
(9) To calibrate the shaft encoder, the production line will need to run for a measured distance.
Enter the distance that the production line will run for in the
Calibration distance (mm)
setting.
(10) Select Start.
(11) Run the production line over the distance that was set at
(12) Select
Stop
.
(13) Copy the
Velocity encoder pulse count
value and enter it into the
Calibration pulse count
(pulses)
setting.
(14) Select
Save
.
(15) Run the production line to make another test print.
(16) Measure the width of the test print, the test print should be equal to the
Width
setting noted
. If not, the
Calibration distance (mm)
value may be inaccurate. Or, the encoder
may have stopped at a position where the pulse signal is generated. This may cause the
encoder to send false pulse signals to the printer. The equation below can be used to
calculate the correct
Calibration pulse count (pulses)
value.
(17) If the label width needs to be adjusted after the
Calibration pulse count (pulses)
setting has
been set, adjust the
Global
stroke pitch goal (mm/stroke)
setting to change the distance
between print strokes (Default value: 0.43mm).
Note:
A print stroke is the line of ink drops which make up each printed character.
New pulse count (pulses) value = N
Old pulse count (pulses) value = O
Label width value = E
Printed label width = P
N = O x (E/P)
