Expansion card "Safety 1-2" (S3)

This expansion card includes all available safety functions. Rotatory synchronous motors
are allowed when using this safety card. All functions fulfill the safety requirements SIL
CL3 according to IEC 62061 respectively performance level PLe acc. to ISO 13849-1.
The safety card restricts feedback capability of the drive (refer to Safety Card Operation
Manual or to the KDN).
10.3.5.1 Safe drive functions S1-2
The safety functions are selected/activated using the digital inputs on the expansion card.
The following functions are available:
Safe Torque Off (STO)
With the STO function, the power supply to the motor is interrupted safely directly in the
drive. This corresponds to an uncontrolled braking in accordance with IEC 60204-1, cate-
gory 0.
Safe Stop 1 (SS1)
With the SS1 function, the drive is stopped by controlled braking and then the power sup-
ply to the motor is interrupted safely. This corresponds to an uncontrolled braking in
accordance with IEC 60204-1, category 1.
Safe Stop 2 (SS2)
With the SS2 function, the drive is stopped by controlled braking and then remains at a
controlled standstill (SOS). This corresponds to a controlled braking in accordance with
IEC 60204-1, category 2.
Safe Operating Stop (SOS)
The SOS function monitors the stop position reached and prevents any deviation outside
a defined range.
Safely Limited Speed (SLS)
The SLS function monitors the drive to ensure that it maintains a defined speed.
Safe Limited Increments (SLI)
The SLI function monitors that the drive maintains a relative position.
Safe Limited Position (SLP)
The SLP function monitors that the drive maintains an absolute position.
Safe Speed Range (SSR)
The SSR function checks the current speed of the drive against maximum and minimum
limiting values.
Safe Direction (SDI)
The SDI function ensures that the drive can only move in one (defined) direction.
Safe Brake Control (SBC)
An external mechanical brake can be controlled by the 2 poles output "SBC+/SBC" of the
safety card. SBC will become active with STO.
Safe Brake Test (SBT)
The safety function SBT can be used for testing the external mechanical brake and the
internal motor holding brake.
10.3.5.2 Safety Notes S1-2
