POS.MONITOR –Position.monitoring
The
POS.MONITOR function monitors the current position of the actuator.
The tolerance band for the set-point value is specified in the
DEADBAND submenu.
A period for alignment of the actual value with the set-point value is specified in the
COMP.TIME submenu
(compensation time).
The compensation time
COMP.TIME starts recording as soon as the set-point value is constant. When the com-
pensation time has elapsed, monitoring starts.
If the control deviation (DEV) of the actual value is greater than the tolerance band of the set-point value during
monitoring, a message is output.
• To do this, a history entry is made in the
HISTORY submenu. For description see “26.2.22.7. History entries in
• The status signal, which is assigned to the message, is indicated at short intervals on the display.
