  • Page 13: Description Of The Safety Function Sto

    With the Safe Torque Off function (STO), the energy supply to the motor is reliably interrupted by switching off the end stage enable and supply to the final output stage. The drive cannot generate torque or any force and so cannot make any dangerous movements. Festo – GDCP-CMMS-ST-G2-S1-EN – 1404NH – English...
  • Page 14 Therefore, when using the “STO” function, do not use motors with holding brakes; use clamping units that permit emergency braking or use automatic locking axis mechanisms. The holding brakes used by Festo motors are not suitable for active deceleration - only for holding a position! Application examples for the STO function are manual manipulations during set-up, equipping and fault clearance.
