Operating Guide
should be set based on the use of the light curtain. If you want to prevent automatic deactivation of the SLS function after the light
curtain detects no objects, use manual acknowledgment. The drive reset is used to deactivate the STO function and to reset the
faults.
The SQS-SS1 function is used as a violation response of the SLS function and assigned to a digital input for requests. The SQS-SS1
function is used in time monitoring mode with a 5.0 s delay for the STO activation. The SQS-SS1 function can operate in the auto-
matic or the manual acknowledgment mode with the drive acknowledgment enabled.
The SQS-SS1 request is assigned to Digital Input 1 of the Advanced safety option board. The SLS 1 control is assigned to Digital
Input 2.
The drive application is used to limit the speed to the desired value. A Sin/Cos encoder is used to measure the speed of the motor
shaft.
