Intended use
The speed monitor monitors standstill, speed, speed range, position and direction in ac-
cordance with EN ISO 13849-1 up to PL e and EN IEC 62061 up to SIL CL 3.
WARNING!
Users must take appropriate measures to detect or exclude errors (e.g. slip-
page or broken shearpin) which cause the frequency of the encoder signal
to no longer be proportional to the monitored speed.
Appropriate measures are:
– Using the monitored encoder to also control the drive
– Mechanical solutions
– Z-frequency monitoring with an additional proximity switch (Ini pnp)
on the same axis

Safety regulations
3.2.1
Safety assessment
Before using a unit it is necessary to perform a safety assessment in accordance with the
Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
3.2.2
Use of qualified personnel
