Numeric Data Field - Quartech 2800 Product Manual

Section 1:

Numeric Data Field

This field will display numeric values associated with drive parameters. The parameter from which data will be retrieved
is specified when the field is created. Signed and unsigned integer values plus floating point formats are supported.
Modification to the value may be enabled or disabled. Individual data value limits are also set for each Numeric Data
field created. If enabled, values are entered by first moving the focus to this field by pressing the Select key, a new
value is then keyed in and the Enter key pressed.
Note:
If a Scale value other than one is assigned with an integer type variable such as Index Distance, please be aware
of the following:
If a decimal value is specified as shown here (Dbl.Decimal.3), then the entry and display of the variable is treated
as a floating point value, however, the limit values remain in the native integer format and in this example would
indicate maximum and minimum counts.
Example: Assume 8000 counts (1 revolution) equals 0.01 inches of travel.
The desired range of travel is from, -1.25 inches to six inches.
Scale: 0.01 Divided by 8,000 equals 0.00000125 (or 1.25e-6)
Maximum Entry Value:
Minimum Entry Value:
The decimal point in the Max and Min Entry Values is a place holder only and is not numerically significant to the
entered limit value. If it is not placed correctly an integrity check error may occur.
Introduction
6.00 / 0.00000125 = 4,800,000
-1.25 / 0.00000125 = -1,000,000
