Safely Limited Speed (Sls) - Allen-Bradley Kinetix 5700 Reference Manual

Safely Limited Speed (SLS)

Table 44 - SLS Instruction Checklist
Test Type Test Description
Initiate a Start command.
• Verify that the machine is in a normal machine run condition
• Verify proper machine status and safety application program status
Operate the machine within the desired speed range.
Set up a trend with expected time scale and the following tags to graphically capture this information:
SFX_Name.ActualSpeed
SLS_Name.SLSLimit
SLS_Name.ActiveLimit
Normal Operation
SLS_Name.Output 1
Initiate SLS demand.
Verify that the drive achieves the speed below the SLS_Name.ActiveLimit without asserting the SLS_Name.SLSLimit output.
While the system is in SLS monitoring state and with the sensor subsystems in a safe state, remove the SLS demand.
• Verify proper machine status and safety application program status
Resume normal machine operation.
• Verify proper machine status and safety application program status
Initiate a Start command.
• Verify that the machine is in a normal machine run condition
• Verify proper machine status and safety application program status
Operate the machine within the normal speed range.
Set up a trend with expected time scale and the following tags to graphically capture this information:
SFX_Name.ActualSpeed
SLS_Name.SLSLimit
SLS_Name.ActiveLimit
SLS_Name.Output 1
Abnormal Operation 1
Initiate SLS demand.
Verify that the drive achieves the speed below the SLS_Name.ActiveLimit without asserting the SLS_Name.SLSLimit output.
While the system is in the SLS monitoring state, initiate a motion command that violates the SLS_Name.ActiveLimit.
• Verify that the SLS_Name.SLSLimit output is asserted and the programmed stop action is initiated
While the system is stopped with the sensor subsystems in a safe state, initiate a Start command.
• Verify proper machine status and safety application program status
While the system is stopped, initiate a Reset command.
• Verify proper machine status and safety application program status
Use this SLS instruction checklist to verify normal operation and the abnormal
operation scenarios.
IMPORTANT Perform I/O verification and validation before validating your safety ladder
program. SFX instruction must be verified within your application.
When possible, use immediate operands for instructions to reduce the
possibility of systematic errors in your ladder program.
Instruction operands must be verified for your safety ladder program.
