Setting functional safety parameters
Refer to the following to set the functional safety parameters.
Page 340 Functional safety parameters that must be set
When using the safety sub-function control by input device, refer to the following.
When using output devices, refer to the following.
When using the safety sub-function control by network, refer to the following.
Page 350 Safety sub-function control by network
When using the SLS function, set the following parameters.
■
SLS deceleration monitor time 1 to SLS deceleration monitor time 4
Refer to the operation sequence and set the time required for the speed monitoring to start after SLS_C (SLS_command) is
turned off. Set the sufficient time for the servo motor to decelerate to or below the SLS speed. Although there are parameters
corresponding to SLS1C (SLS1 command) to SLS4C (SLS4 command), it is not necessary to set the parameters
corresponding to commands that are not enabled.
■
SLS speed 1 to SLS speed 4
Refer to the operation sequence and set the speed threshold for speed monitoring. Although there are parameters
corresponding to SLS1C (SLS1 command) to SLS4C (SLS4 command), it is not necessary to set the parameters
corresponding to commands that are not enabled.
■
SLS speed detection delay time
Set the error detection time for the detected speed. The setting value of this parameter changes the delay time from when the
SLS speed is exceeded during speed monitoring to when the STO function is activated.
