7.4.1.3. Controlling the measuring system
The option "Vmax" of the menu enables entering the tolerated steps per cycle of the actual value..
This enables controlling a measure-system.
The required value is calculated of the CamCon's actual cycle-time, the measuring system's physical
resolution und the device's Speed.
Note:
The resolution needs to be a physical measure, e.g. if for a measuring system 4096
Impulses are calculated to 3600 by a (3600/4096)gear, the resolution must be set to 4096.
Example: Cycle time = 0.5ms / resolution = 360 / speed of machine = 180 min -1.
Value =
resolution * plant speed
60 * 1000
* Cycle time + margin
360 * 180
60 * 1000
* 0.5 + 5 = 5.54
≈
6
The result is rounded and filled in "
Vmax"
If the CamCon detects a step of more than 6 impulses at the actual value an error report
"Ist-Err:5"
is
shown.
If a zero is filled in here, the controll is deactivated, and a maximum of 9999 is possible.
