•
Insert reel with large diameter to get a signal according to the large diameter
from the distance sensor, or set PLC diameter signal to a large value.
•
Input the actual (large) reel diameter as
Diameter 2
as written above (fig. 16).
After confirmation with
↵
key the diameter is saved together with the referring
voltage signal.
Adjustment of pilot control
To get the electronic unit calculating the pilot control correct, a certain torque has
to be assigned to a certain diameter:
•
Set parameter
Pilot control
to
No.
•
Proceed for a test run. If the control loop runs stable at a diameter as large as
possible, the actual reference value and, after pressing the
↑
key, the actual
output value
can be read from the display (fig. 10). Note these values:
Actual reference value
REF
= ________________ [N, lbs]
Actual output value
OUTPUT = ________________ [V, mA]
•
Terminate test run
•
Calculate the required torque value as a percentage of the maximum output
signal which is 10V or 20mA:
The torque for the pilot control is now determined.
•
Set parameter
Pilot control
to
Yes.
•
The reel diameter must be the same as during the test run.
•
When in the main operating menu, press
