11.3.4 Expansion card "Safety 2-2" (S4)
This expansion card (Basic version) includes various safety functions for the safe operation
of drive shafts. Rotatory synchronous motors are allowed when using this safety card. All
functions fulfill the safety requirements SIL CL2 according to IEC 62061 respectively per-
formance level PLd according to ISO 13849-1.
The safety card restricts feedback capability of the drive (refer to Safety Card Operation
Manual or to the KDN).
11.3.4.1 Safe drive functions S2-2
The safety functions are activated using the digital inputs on the expansion card. The fol-
lowing 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, category
0.
Safe Stop 1 (SS1)
With the SS1 function, the drive is stopped by controlled braking and then the power supply
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 con-
trolled 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 Speed Range (SSR)
The SSR function checks the current speed of the drive against maximum and minimum lim-
iting values.
Safe Direction (SDI)
The SDI function ensures that the drive can only move in one (defined) direction.
