Four sets of SLS speed and SLS deceleration monitor time can be set with the SLS function. The following table lists the SLS
deceleration monitor time and SLS speed that are enabled by the SLS1 command, the SLS2 command, the SLS3 command,
and the SLS4 command.
The following shows a sequence when the SLS1 command and SLS2 command are simultaneously turned off. When multiple
speed monitoring instances are executed simultaneously, the smallest SLS speed threshold is enabled. In the following
sequence, SLS speed 2 is a smaller value than SLS speed 1, so if both the SLS1 command and the SLS2 command are
enabled, monitoring by SLS speed 2 is enabled.
SLS command SLS deceleration monitor time SLS speed
SLS1 command [Pr. PSA07 SLS deceleration monitor time 1] [Pr. PSA11 SLS speed 1]
SLS2 command [Pr. PSA08 SLS deceleration monitor time 2] [Pr. PSA12 SLS speed 2]
SLS3 command [Pr. PSA09 SLS deceleration monitor time 3] [Pr. PSA13 SLS speed 3]
SLS4 command [Pr. PSA10 SLS deceleration monitor time 4] [Pr. PSA14 SLS speed 4]
