4.1   System Set up

Basic calibration cannot be performed if E-STOP is open,

or if RUN/STOP is in run mode.

A complete flow chart is shown in Figure 6.

To begin basic calibration, do the following:

Press SHIFT,

Press PROGram,

Use   or    to select 

)PROGRAM: CALIBRATE(,

Press NEXT to select 

)CALIBRATE BASIC(,

Press NEXT to display 

)SELECT SYSTEM(.

Use 

é or ê  to select desired system type. See Figure 1 for a

description of system types.   If using a regenerative drive, see

Section 6.9 to determine system type.

Then continue through the flow chart at right entering the

desired data in each screen.

4.2   Tension Sensor Calibration

NOTE: Continuing beyond this point will erase any

previous sensor calibration in this setup.

Sensor calibration will require loading the sensor roll

with a known force.  The known force will be applied

using a weight and a temporary web as shown below.

The temporary web should be threaded as the web

would normally be threaded in the machine to ensure

the same wrap angles.  In wide web applications, the

known force should be applied near the center of the

sensing roll using a narrow web such as a rope.

Follow the steps at the right to calibrate the tension

sensors.
