These functions are part of the standard scope of the drive and can be used without
requiring an additional license. These functions are always available. These functions do
not require an encoder and/or do not place any special requirements on the encoder
used.
– Safe Torque Off (STO)
Safe Torque Off is a safety function that prevents the drive from restarting
unexpectedly, in accordance with EN 60204-1. STO prevents the supply of energy to
the motor which can generate a torque and corresponds to Stop Category 0.
– Safe Stop 1 (SS1, time controlled)
Safe Stop 1 is based on the "Safe Torque Off" function. This means that a Category 1
stop in accordance with EN 60204-1 can be implemented.
