Page 4: Scope
STO enables safe working and has a wide range of use in motion control/ systems with moving axes. The advantage of the integrated STO safety function compared with standard safety technology using electromechanical switchgear is the elimination of separate components and the effort that would be required to wire and service them. -
Page 5: Activating Sto
2- STO Fault LED at Roborun+ utility in failure This failure can have several internal and external reasons. If the failure is shown, please check the cabling and the signals to STO 1 and STO 2. Both signals much have at all times the same level. ... -
Page 6: Sto Firmware Implementation
Same status LED pattern is used for undervoltage and overvoltage faults and that should not be confusing. If STO fault appear it is normal for the controller voltage to be off and undervoltage fault to trigger. Either way this Status LED pattern indicates a situation that should be treated with caution. -
Page 7: Stt - Sto Self-Test
This process is applicable only on motor controllers with latest firmware v2.x installed. The result of the test is returned automatically. In case of fault the Respective STO Fault bit in the Fault Flags is set. The fault is triggered when: ... -

= W2 bottom fault 13. Installation – Maintenance STO Installation test The STO circuit needs to be tested before first installation and at least every 3 months according to the below sequence: 1. Activate STO (both logic level 0) 2. -
Page 9: Sto Voltage Source Specification Attention
14. STO Voltage source specification attention In order to have maximum response at STO implementation, user/installer/integrator should use voltage source with low output capacitance. In any other case, latency in activation might occur. 15. Compliance and Safety Metrics The STO function is compliant to: ...
