Safety Integrated List for 6SL3126-1TE21-8AA4 (S120 Cold Plate Single Motor Module)
This module supports full S120 Safety Integrated (أساسي + ممتد + Advanced Safety). Hardware is ready for extended safety functions. CU320 / CU320-2 control unit, safety license, safety encoder (for partial functions) and ProfiSafe F-CPU are required to activate relevant functions.
Max safety rating: SIL3 / PLe (ايزو 13849-1)
Advanced Safety Functions (Advanced License Mandatory, Safety Encoder Required)
- SLP Safely-Limited Position: Safe position range monitoring, software limit
- SP Safe Position: Safe absolute position monitoring
- SCA Safe Cam: Safe electronic cam
6SL3126-1TE21-8AA4 (cold plate) and 6SL3120-1TE21-8AA4 (air cooling) have identical safety capability, only cooling method differs.
STARTER / Startdrive for Safety Integrated configuration. Mandatory safety acceptance test (F-test) before commissioning handover.
S120 Basic Safety vs Extended Safety (for 6SL3126-1TE21-8AA4)
Core summary: Basic Safety = Torque removal, time-based stop; Extended Safety = Speed / position monitored safety, limited operation permitted
Basic SS1 (Time-controlled): Decelerate via OFF3 ramp, countdown only. STO activated once timer expires. No actual speed feedback check. STO will still trigger after timeout even if axis is jammed or overspeeding during deceleration.
Extended SS1 (SBR/SAM): OFF3 deceleration ramp active with deceleration ramp monitoring (SBR) / acceleration monitoring (SAM). If deceleration is too slow or overspeed occurs, safety fault + STO is triggered before timeout.
Advanced safety SLP/SP/SCA belong to position-based extended safety, also requiring license and safety encoder.
Cold plate: 6SL3126
Internal air cooling: 6SL3120
External air cooling: 6SL3121
Current ratings are one-to-one mapped. Safety functions are fully identical, only cooling differs.
- Additional Note on Safety Capability
All models within 6SL3126 series share the same safety specification:
✅ Standard basic safety: ستو, time-controlled SS1, SBC (free, no license)
✅ Hardware ready for extended safety: SS2, SOS, SLS, SDI, SBT, SLP (axis license + safety encoder required)
✅ Uniform safety rating: SIL3 / PLe
