1.5 Functional Safety
Beta Drives: Functionality Safety of AKD2G is neither approved nor certified. Do not use
this functionality in applications with functional safety request.
There are three optional levels of Functional Safety implementation for AKD2G:
Option 1 (SIL2 PLd): STO, activation by safe I/O
Option 2 (SIL3 PLe): STO, SS1-t, SBC, SBT, SDB, activation by safe I/O or FSoE
Option 3 (SIL3 PLe): STO, SS1-t, SS1-r, SS2, SLS, SSM, SSR, SDI, SLA, SAR, SLI,
SLP, SCA, SBC, SBT, SDB, activation by safe I/O or FSoE
Resulting Functional Safety classification (SIL and/or PL level) must be calculated across
the drive system.
The safety properties given by Kollmorgen can be reached if the Kollmorgen components are
used. Refer to the matching AKD2G-S Installation Manual for full information on the installed
functional safety option.
Parameterizing of the safety functions shall be done by trained personnel only. The level of
experience shall beappropriate tothe complexity and safety integrity level of the drive sys-
tem.
CAUTION
High electrical voltage!
Risk of electrical shock! The safety functions do not provide an electrical separation from the
power output. If manual access to power terminals is necessary,
disconnect the drive from mains supply,
consider the discharging time of the DC-Bus link.
