SLS with stop response "STOP B"
Table 10- 25 Function "Safely-Limited Speed without encoder" with "STOP B"
No. Description Status
Note:
The acceptance test must be carried out separately for each configured control and each SLS speed limit used.
Control may be via TM54F or PROFIsafe.
Initial state
• Drive in "Ready" state (p0010 = 0)
• Safety Integrated Extended Functions enabled (p9601.2 = 1)
• Safety functions enabled (p9501.0 = 1)
• Safety configured without encoder (p9506 = 1)
1.
• No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]); see note "non-
critical alarms" in section "Acceptance tests".
2. It may be necessary to take measures in the higher-level control to be able to exceed the active speed limit
Configure and activate trace recording
• Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
• Record the following values: r9714[0], r9714[1], r9720, r9721, r9722
• Select the time interval and pretrigger so you can recognize when the active SLS
limit has been exceeded and the subsequent drive responses
Select SLS with level x
Switch on the drive and specify the setpoint above the SLS limit
• Check that the drive is moving, and after the SLS limit (p9331[x]/9531[x]) has been
exceeded that it is decelerated along the OFF3 ramp before STOP A becomes
active
Check whether the following Safety messages are pending:
• C01714 (x00), C30714 (x00); x = 1...4 depending on the SLS level (safely limited
speed exceeded)
• C01701, C30701 (STOP B initiated)
3.
• C01700, C30700 (STOP A initiated)
Analyze trace:
• If r9714[0] (unit [µm/Safety clock cycle] or [m°/Safety clock cycle]) exceeds the
active SLS limit, a Safety message (r9722.7 = 0) becomes active
• A STOP B is initiated as a consequence (with subsequent stop STOP A)
For better analysis, display the following bit values:
• r9720.4 (deselection SLS) and r9720.9/.10 (selection SLS level)
• r9721.12 (STOP A or B active)
• r9722.0 (STO active; set for STOP A)
• r9722.1 (SS1 active; set for STOP B)
• r9722.4 (SLS active) and r9722.9/.10 (active SLS level)
4.
• r9722.7 (internal event; set with the occurrence of the first Safety message)
