4.4.2.2
Adapter for incremental encoders
The adapter records the data between the encoder and drive and makes it available to the
PNOZ ms2p TTL (Coated Version) via the RJ45 socket.
Pilz supplies complete adapters as well as ready-made cable with RJ45 connector, which
can be used when making your own adapter. The range of products in this area is con-
stantly being expanded. Please contact us about the range of adapters that is currently
available.
4.4.3
Incremental encoder and proximity switch on one axis
In order to increase the availability, a proximity switch and an incremental encoder can be
configured on one axis for the speed monitor. The speed monitor then monitors 3 signals
on an axis: Track A and track B of the incremental encoder and the proximity switch
Standstill monitoring
Standstill is detected when at least two of these signals fall below the standstill frequency.
Monitoring for broken shearpins
If the Broken shearpin monitoring option is activated, a shearpin break is recognised if
}
both signals of the incremental encoder fall below the set standstill frequency (stand-
still)
and
}
the proximity switch exceeds the set standstill frequency (rotating shaft).
The recognised broken shearpin leads to safe condition (see status B2 in "Signal statuses"
table in Chapter 8 of the operating manual). If individual or multiple signals change, the sys-
tem may leave a safe state (see "Signal statuses" table).
Hazards that can arise through an automatic restart must be excluded from the user pro-
gram.
