If a diameter sensor has been installed and calibrated,
use the DBA Setup (Section 6.0B) of this manual. If no
diameter sensor will be used for the application, OBA
Setup (Section 6.0A) must be completed.
NOTe: Press SeND anytime a setting on the Setup
screen is changed. The SeND button will send all
of the setup values to the RSD100. Press the Re-
TRIeVe button to read the SeTUP values that are
already stored in the RSD100.

The OBA setup parameters are visible in the lower left of
the SETUP screen when OBA is selected. They are not
accessible if DBA has been selected.
The RSD100 must be run in manual mode to determine
the OBA Settings. A full roll will be needed. Run the
machine at 20% of full speed with normal operating
tension (minimum tension for variable tension machines).
Manually adjust the output of the RSD100 to achieve
stable operation at full roll and core (Refer to Manual
Operation of RSD100 Output). Record and enter these
output values into the OBA Settings window.

1. Measure the Full Roll Diameter and Core Diameter.
2. Calculate the Diameter Ratio. DIAMETER RATIO =
Full Roll Diameter / Core Roll Diameter.
3. Round this number off to an integer and enter it in
the DIAMETER RATIO field of the OBA settings
window.

1. Open the Diagnostics and Setup windows.
2. Place RSD100 in manual mode (Refer to Manual
Operation of RSD100 Output).
3. Adjust the tension on the machine for the minimum
operating tension. For constant tension machines,
run the machine at normal operating tension.
4. Start the machine with a full roll and run machine at
20% of maximum speed.
5. Manually adjust the OUTPUT of the RSD100 until
the dancer arm is stable in the middle of its travel.
6. Round this number to an integer and enter it in the
FULL ROLL OUTPUT field.

The procedure for determining the CORE OUTPUT is
the same as the FULL ROLL OUTPUT [%] procedure,
except it is done at core. However, if the roll is not
at core and the machine needs to run until core, then
CORE OUTPUT [%] can be approximated using the
following steps:
1. CORE OUTPUT = FULL ROLL OUTPUT / DIAM-
ETER RATIO (Temporary Value)
2. Set Gain = 50 with Proportional (P)= 40, Integral
(I)= 10 and Derivative (D)= 50.
3. Place the RSD100 in Automatic operation and
slowly take the machine to normal running speed.
Note: The control is not tuned yet for optimum
performance. If the dancer arm hits an end-of-
travel limit, reduce the Proportional and Deriva-
tive gains or decrease the machine acceleration /
deceleration times.
4. Run the machine to near core and then slow ma-
chine down to 20% of maximum speed.
5. When at core, record the RSD100 OUTPUT. Round
this number to an integer and input this value in the
CORE OUTPUT field in Setup.
