4.2.2.2 Adapter for incremental encoders
Adapter for incremental encoders 4-
The adapter records the data between the incremental encoder and the
drive and makes it available to the speed monitor via the RJ-45 female
connector.
Pilz supplies complete adapters as well as ready-made cable with RJ-
45 female connectors, which can be used when making an individual
adapter. The range of products in this area is constantly being expand-
ed. Please contact us about the range of adapters that is currently avail-
able.
4.2.3 Incremental encoder and proximity switch on one axis
Incremental encoder and proximity switch on one axis 4-
In order to increase the availability, a proximity switch and an incremen-
tal encoder can be configured on one axis for the speed monitor. That
way the speed monitor can monitor 3 signals on one 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 fre-
quency (standstill)
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). If individual or multiple signals
CAUTION!
The maximum permitted supply voltage on the incremental
encoder must not exceed 5 VDC. Higher voltages would dam-
age the unit.
