I've just reviewed Yaskawa Sigma-5 brochure and noted that they claim compliance with the following safety standards:
EN954-1: Safety Category 3
EN60204-1: Stop Category 0
IEC61800-5-2: Safe Torque Off (STO)
Can somebody give more details / idea about this standards (is EN61800-2, -3, -5 standard similar to IEC61800-2, … ?). Or, maybe, we can take this opportunity to hold a general drive safety discussion:
1. what are today's standards and reasonable servo amplifier / drive / motion controller safety requirements (drive level, not machine one)?
2. what Yaskawa competition Rockwell, Siemens, Baumueller, and other claim / offer in this connection?
3. for drive manufacturers, what is the meaning of safety standard compliance on HW, SW / FW , communication levels etc?
