Safety
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
