SLI (Safely Limited Increment)
Monitoring of the maximum increment
Amount:
cf.
“Overview of the safety modules
Function:
monitoring of the maximum increment
Input:
standardised position signal / speed signal V and X from encoder interface.
Direction LEFT / RIGHT.
RESET function
Violation of the permitted monitoring range is saved and requires a
RESET confirmation. RESET confirmation is alternatively carried out via:
▪
RESET function in the group Input elements.
▪
Function button at the front side of a basis group
▪
Fieldbus inputs via reset block
NOTICE:
It must be programme-technically ensured that in case of a triggering event.
Otherwise, the SLI-block could not be reset again.
When activating the function, it must be programme-technically ensured that CW
and CCW never become 1 at the same time. Otherwise, an alarm is emitted.
Description of the function:
•
Montoring of the maximum permitted increment = relative travel range for continuous travel
in the jog mode.
•
Calculation of the current rotational direction RX from the position signal / the speed
signal X
•
Determination of the relative travel distance after the start of the movement
•
Monitoring for observation of the given direction and of the max. given travel distance
NOTICE
:
In case of a reset, connections in the block must be reset to
“0”.
Otherwise, the function cannot be
reset.
If the function is activated, it is not permitted that
“cw” and “ccw” are activated simultaneously for
the input signal. If both options are activated, an alarm is triggered.
