6.4 FSM 2.0 – MOV
6.4.1 Features
The Functional Safety Module FSM 2.0 – MOV serves as an expansion of the servo positioning
controller ARS 2000 FS to implement the safety functions:
STO – Safe Torque Off
SS1 – Safe Stop 1
SS2 – Safe Stop 2
SOS – Safe Operating Stop
SLS – Safely-Limited Speed
SSR – Safe Speed Range
SSM – Safe Speed Monitor
SBC – Safe Brake Control
When suitable position transmitters are used and with suitable activation of the safety module, the
requirements are fulfilled in accordance with EN 61800-5-2 up to and including SIL3 and in
accordance with EN ISO 13849-1 up to and including Category 4 / PL e.
Depending on the encoders used for position recording, it is possible that only SIL2 is
implemented
It is equipped with a floating feedback contact.
It can be simply plugged into the basic unit from the outside, so that it can be used for upgrading
systems that are already equipped with ARS 2100 FS servo positioning controllers.
It is exclusively suitable for the ARS 2000 FS product range.
It offers a user-friendly parameterisation with the Metronix ServoCommander® software with
including the SafetyTool.
DANGER!
The function STO as a sole safety function is not sufficient for drives under
permanent torque, such as hanging loads.
DANGER!
For drives, the safety functions must be validated after installation and after any
changes to the installation.
This validation must be documented by the commissioning engineer.
