AKD2G-S Installation, Safety 1 | 10 Functional Safety
10.1 General notes
Beta Drives: Functional Safety of AKD2G is neither approved nor certified. Do not use this
functionality in applications with functional safety request.
Resulting Functional Safety classification (SIL and/or PL level) is calculated across the drive
system. The drive system usually consists of
motion controller (e.g. AKC/KAS),
safety controller (e.g. KSM),
servo drives (AKD2G) and servo motors (e.g. AKM2G),
motor brakes, feedback systems,
cables to connect drive and motor,
sensors/actors.
The safety properties listed in this chapter can be reached if the Kollmorgen components are
used.
Only properly qualified personnel are permitted to perform such tasks as installation, setup
and parameterization.
Mechanical installation: only by qualified personnel with mechanical expertise according
to IEC 60417-6183.
Electrical installation: only by qualified personnel with electrotechnical expertise accord-
ing to IEC 60417-6182.
Parameterizing Functional Safety: only by trained personnel with expertise appropriate
to the complexity and safety integrity level of the drive system.
Verification/Validation: only by trained personnel after any changes to the installation.
The expertise of the personnel must be appropriate to the complexity and safety integrity
level of the drive system.
High electrical voltage!
Risk of electrical shock! The safety functions do not provide an electrical separation from the
power output. If manual access to the motor or drive power terminals is necessary,
disconnect the drive from mains supply,
consider the discharging time of the DC-Bus link,
ensure the cabinet is safely disconnected and protected against unintended switch-on
(for instance, with a lock-out and warning signs).
10.2 Use as directed
Safety functions are intended to reduce the risk of the machine operation to the required tol-
erable risk. To achieve functional safety, the wiring of the safety circuits must meet the
safety requirements of IEC 60204, ISO 12100 and ISO 13849.
The network, where the drive is connected to, must be secured according to state-of-the-
art information technology security requirements.
The user IT specialists shall analyze whether further security requirements are applic-
able to ensure functional safety.
The drive firmware can be updated without opening the AKD2G while it is built into the
machine. The parameter sets must be reloaded, verified and proof tested before normal oper-
ation is started.
