The term “Safe Torque Off” is defi ned in the standard for safety functions in adjustable speed drives.
Safe Torque Off (STO)
The STO function is the most common and basic drive-integrated safety function. It ensures that no torque-generating energy can continue to affect a motor and prevents unintentional start-ups.
