Safe Torque Off
6-3
AC30 series Variable Speed Inverter
Alignment to European Standards
EN ISO13849-1:2008
(Safety of machinery – Safety-related parts of control systems)
STO aligns internally to the following aspects of this standard:
Architecture according to Category 3:
Solid lines represent the STO control paths.
Dashed lines represent reasonably practicable fault detection.
Key:
I1, I2 = user terminal
L1, L2 = logic
O1, O2 = methods of enabling or disabling output power devices
i
mxy
=
interconnecting means
m
x
= monitoring
c
= cross monitoring
Category 3 general requirements are:
A single failure, and any consequential failures, will not lead to loss of the STO safety function.
Failure of more than one component can lead to the loss of the STO safety function.
