SLS (Safely Limited Speed Control)
Monitoring of a minimum speed
Amount:
cf.
“Overview of the safety modules“
Function:
monitoring of a minmum speed
Eingang:
standardised position signal X from the encoder interface
RESET-function: Violation of the permitted monitoring range is saved and requires a RESET
confirmation. The RESET confirmation is alternatively carried out via:
▪
RESET function in the group of the input elements.
▪
Function button at the front side of a basis group
▪
Fieldbus inputs via Reset block
Description of the function:
•
Monitoring of the maximum speed or the maximum rotational speed of a drive.
•
Calculation of the current speed V from the position signal, or rather, from the digital speed
signal X
•
Comparison of the actual speed to the parametrised speed threshold
•
Monitoring of a change of speed from fast to slow by means of the selected SSX -ramp
•
Error distance monitoring
