2. Once step 1 is complete, the dancer should be allowed to
move freely. Move the dancer up and down to make sure there
is no mechanical binding. Then move the dancer to the
approximate position of “WEB OUT”. Monitor the value of
Parameter 595, the analog #1 raw output. The value should
normally be greater than 1500. The default value that has
been arrived at for the setup of the production units for the
“web out” setting is 1500 (Parameter 558-Dancer Full
Position). This sets the internal logic to recognize a web out at
the position of 1500 which should be approximately 5/8 inch
to 3/4 inch below full-up at auto slack tension (5 to 5-1/2
PSI). The Goss preferred method for establishing “web out”
is to position dancer so that the “flag” or “hammer” is just
touching shock absorber (no compression) observe Parameter
595, note value, and subtract 100 (drive units), then enter that
value into Parameter 558 (Dancer Full Position). Note:
Parameter 559 (Dancer Mid Position) must be set to half the
value of Parameter 558 (Dancer Full Position).
This is all that is required prior to starting the Drive. The following
suggested adjustments should be made during initial checkout.
Permanently store the parameters in EEPROM before proceeding.
Important: The magnetic pickup signal is summed with the pulse
generator for the Emulate signal in the GSD Console
Panel. Thus, when the Drive is in the emulate mode, the
magnetic pickup and associated circuitry are not part of
the system.
Drive Started
Emulate Mode – Since there is no paper from the reel to the press
during emulate mode, or the belts are up and not contacting the paper,
place the dancer in the center position for this portion of the testing
using the block method discussed above.
1. Determine the proper gear pulse per revolution from the printing
diameter cross reference chart (Tables 3 through 6). Set the “Press
Ref PPR” Parameter 561 to the proper value.
2. Determine the maximum belt motor RPM versus maximum press
speed (IMP/HOUR) from this same chart and enter the proper
value in Parameter 608 – Forward Speed Limit.
3. Determine the maximum drive shaft speed of the press (usually
2566 RPM), versus maximum press speed, in KIPH, from this
same chart and enter this value in Parameter 562, “Max Press Ref
RPM”, the major tracking adjustment for the RTP Drive.
