5.3 Calibrating the position system
To calibrate the position system (adapt the internal device processing to mirror actual
conditions at the place of installation) it is necessary to determine the system limits, cali-
bration point, calibration factor and unit.
•
The system limits define the max. possible working range. An error will be
triggered if values exceed or fall below the defined range.
PLEASE NOTE!
To avoid system limit errors ensure sufficient clearance between the sys-
tem limits and the switching points.
•
The operating range must not exceed 32768 rotations of the device shaft.
•
The preset position value is a defined position point (calibration point).
•
The calibration factor is the adaption factor between system units and device units.
It is assumed that this ratio is constant.
If unknown, it is possible to determine the calibration factor via the menu item
“Options
Determine calibration factor” (see Chap.5.3.2).
In this instance it is possible to determine the calibration factor with the aid of 2
calibration points, the interval between which should be as great as possible but must
not exceed the system limits.
