S700 Safety Guide | 6 Appendix
6.4.2 Conformance with CE
CE Declarations of Conformity can be found on the Kollmorgen website.
The servo amplifiers have been tested by an authorized testing laboratory in a defined con-
figuration, using the system components that are described in this documentation. Any diver-
gence from the configuration and installation described in this documentation means that you
will be responsible for carrying out new measurements to ensure conformance with reg-
ulatory requirements.
Kollmorgen declares the conformity of the products S700 with the following directives
EC Machinery Directive (2006/42)
EC EMC Directive (2014/30/EC)
EC Low Voltage Directive (2014/35/EC)
Concerning noise immunity the servo amplifier meets the requirements to the 2nd envir-
onmental category (industrial environment). For noise emission the amplifier meets the
requirement to a product of the category C2 (motor cable up to 10 m). With a motor cable
length from 10 m onwards, the servo amplifier meets the requirement to the category C3.
This product can cause high-frequency interferences in non industrial environments which
can require measures for interference suppression.
Functional Safety Conformance (STO) according to EC Machinery Directive
STO (Safe Torque Off)
The S700 servo amplifier offers a two channel STO function (Safe Torque Off). The function
blocks the trigger pulses of the power transistors (pulse inhibitor).
The STO safety concept is certified by the TÜV. The safety circuit concept for realizing the
safety function "Safe Torque Off" in the servo amplifiers S700 is suited for SIL CL3 according
to IEC 62061 and PLe according to ISO 13849-1.
The subsystems (servo amplifiers) are totally described for safety technics with the char-
acteristic data SIL CL, PFHD and TM.

SIL2 / PLd solutions can be implemented with single-channel or dual-channel control with
simple safety switching devices.
SIL3 / PLe solutions requires a safety control that periodically tests the safe switching of the
pulse inhibitor by analyzing the feedback signal.
Expansion card "Safety 2-2" (S4)
This expansion card (Basic version) includes various safety functions for the safe operation
of drive shafts. All functions fulfill the safety requirements SIL CL2 according to IEC 62061
respectively performance level PLd according to ISO 13849-1. The functional safety is cer-
tified by the TÜV. Safety characteristic data are listed in the Instructions Manual of the expan-
sion card.
Expansion card "Safety 1-2" (S3)
This expansion card (full version) includes several safety functions. All functions fulfill the
safety requirements SIL CL3 acc. to IEC 62061 respectively performance level PLe acc. to
ISO 13849-1. The functional safety is certified by the TÜV. Safety characteristic data are lis-
ted in the Instructions Manual of the expansion card.
