Sls Function - Mitsubishi Electric MELSERVO-J5 MR-J5 Series User Manual

SLS function

Outline
This function monitors whether the speed is within the prescribed speed limit. If the speed exceeds the specified speed limit,
the STO will shut off energy. Upon detection that the servo motor speed exceeds the SLS speed, the STO function is
activated. The SLS function monitors both the command speed and feedback speed.
Sequence outline
The SLS function is activated by turning off SLS_C (SLS_command). After SLS_C (SLS_ command) is turned off, speed
monitoring starts after the delay time specified by the functional safety parameter has elapsed. During speed monitoring, the
function monitors whether the servo motor speed is within the SLS speed set by the functional safety parameter. Speed
monitoring ends by turning on SLS_C (SLS_command).
