Safety Integrated basic functions

9.1General information

Safe torque off (STO)

STO is a safety function that prevents the drive from restarting unexpectedly, in accordance with EN 60204-1, Section 5.4.

Note

When a drive object that has Safety Integrated functions released is switched to "Parking" mode, the Safety Integrated software responds by activating STOP without generating a separate message.

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)

The SBC function permits the safe control of a holding brake.

SBC is not supported by chassis components. Power Modules Blocksize also require a Safe Brake Relay for this function.

Safety Integrated extended functions

Safe Stop 1 (SS1, time and acceleration controlled)

The SS1 function 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 Stop 2 (SS2)

The SS2 function brakes the motor safely with a subsequent transition to "Safe Operational Stop" (SOS).

Safe Operational Stop (SOS)

"Safe Operational Stop" (SOS) protects against unintentional movements. The drive is in closed-loop control mode and is not disconnected from the power supply.

Safely Limited Speed (SLS)

The "Safely Limited Speed" (SLS) protects against excessively high drive speeds.

Safe Speed Monitor (SSM)

The SSM function reliably monitors the speed limit and issues a safe output signal, but without a response function.

Prerequisites for the extended functions

An appropriate license

Activation via PROFIsafe or TM54F

NOTICE

Per single Control Unit, either control via PROFIsafe or TM54F is permitted. Mixed operation is not permitted.
