4.2.5. PLL measuring system input
Systems with Phase - Lock - Loop data recording. In these systems the actual value is found through
interpolation of initiator impulses. This measuring system is applied to machines with constant speed
and with a cyclic pulse.
= Initiator impulse
= Found actual value
The Initiator can be connected to any free input of the CamCon.
Note: For CamCon DC115 a special input is available on the 25pol. SUB-D plug.
See also chapter "7.4.1.6.5. PLL measuring system" on page 51.
4.2.6. Timer as a measuring system
Systems which are controlled by elapsed time. In this case the CamCon makes a time available with a
time basis of minimum 1 ms as actual value. Through laying on of input signals it is possible to
influence the elapsed time. This measuring system is applied to machines with a fixed time scanner as
a control feature, e.g. washing machines.
See also chapter "7.4.1.6.6. Timer way simulation" on page 51.
4.2.7. RS232 as a measuring system
Systems, receiving their actual position through the RS232 interface, e.g. for a junction of a Stegmann
POMUX linear scale to a RS232 data output.
Warning The activation of this measuring system blocks the RS232 interface for
programming. This measuring system is only reasonable with a CamCon
DC50/51.
