Safety Integrated Basic Functions

The Safety Integrated Basic Functions are part of the standard scope of the drive and can be
used without 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 to avoid unexpected startup in accordance with
EN 60204-1. STO prevents the supply of power to the motor, which can produce a
torque. This is equivalent 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.
● Safe Brake Control (SBC)
Safe Brake Control is used to safely control a holding brake.
Note regarding Power/Motor Modules in the chassis format: For the chassis format, SBC is
1)
only supported by Power/Motor Modules with article number ...3 or higher. A Safe Brake
Adapter is also needed for this design.
Note regarding Power/Motor Modules in the blocksize format: Blocksize Power Modules
2)
also require a Safe Brake Relay for this function.
Note
Parallel use of Safety Integrated Functions
All Safety Integrated Functions can be used simultaneously.
Exception: If SOS and SLS are activated simultaneously, SOS has higher priority and
overrides the SLS reaction.
