3-16 Start-Up Instructions
Speed Match The Drive is set up at the factory to ensure an accurate speed match
between the new roll coming up to speed and the existing web. This is
accomplished by using the at set speed algorithm in the Drive. The up
to speed tolerance (Parameter 709) sets the hysteresis in motor RPM
around the at speed point. When the new roll is speed matched with
the press speed reference, and the motor is not at zero speed, the
Drive will go into Mode 5 which is speed match. This turns on digital
output #1 to produce an external indication to the paster panel.
Dancer Calibration Drive Not Started
Dancer Voltage – The dancer potentiometer voltage should always
be plus when the dancer is in the up or “WEB OUT” position.
Determine whether the specific application is right hand or left hand
as observed from the GSD console looking at the reel. Check to
assure that the Drive wiring conforms to applicable configuration.
Dancer at Center Position – The dancer at center position or at a
horizontal level position is a mechanical benchmark which will
continue to be used throughout the life of the press. One way of
quickly and reputably setting the dancer at center position is to
establish a mechanical data point for the placement of a machined
block that acts as a setup block to restrict the dancer of downward
movement only during setup and troubleshooting with no paper
webbed from the reel. Two of these machined blocks are
recommended, one for each side of the dancer.
Once the dancer potentiometer has been set up for 0.0 volts DC, ± 0.2
volts, with the dancer in the horizontal level position, the following
normal adjustments to the setup parameters can be made prior to
starting the Drive.
Preliminary Steps:
A. Disable the process trim system by setting Parameter 628 to zero.
B. Disable the integral channel of the P/I Regulator by setting
Parameter 567 to zero.
1. Using a digital voltmeter, monitor test point TP14 to TP12 on
the Digital Reference Adapter Board. The voltage should be
0.0 volts DC with the dancer in the horizontal or dancer
center position. If there is a need to trim the voltage to a value
closer to zero, use Parameter 551. (eg. V@TP14 = + 0.5
volts; using the DHT find Parameter 551, arrow down to the
value; use the “DEC” key to change from the default value of
0.0 volts to a negative number. Continue to enter DEC until
the value at TP14 is as close as possible to 0.0 volts.)
