2-6 Safety Instructions for Electric Drives and Controls REFUspeed RS51

2.7 Protection against dangerous movements
Dangerous movements can be caused by faulty control or the connected
motors. There are various causes:
• Incorrect wiring or cable connections
• Inappropriate or wrong operation of equipment
• Malfunction of sensors, encoders and monitoring circuits
• Defective components
• Software errors
Dangerous movements can occur immediately after equipment has been
powered-up or even after an unspecified time of trouble-free operation.
The monitoring functions in the drive components make faulty operation
almost impossible. Regarding personnel safety, especially the danger of
bodily harm and property damage, this alone should not be relied upon to
ensure complete safety. Until the integrated monitoring functions become
active and effective, it must be assumed in any case that some faulty
drive movements will occur. The extent of these faulty drive movements
depends on the type of control and the state of operation.
