1.4 Basics Configuration Logic PNOZmulti elements zusammengestellte and Wiring Texte
The functions on the PNOZmulti devices
are configured using the PNOZmulti
Configurator.
Logic elements affect the state of the
function elements. Logic elements include:
Logic connections e.g. AND, OR
Time elements
Event counter
Speed monitor
Start element
Connection point
Press elements
Muting
Logic elements can be linked with
the outputs of the function elements
other logic elements
the inputs of the output elements
Speed monitor
The speed monitor logic element is
used to configure the PNOZ ms1p/
PNOZ ms2p speed monitor. The
speed monitor monitors
Standstill
Overspeed
Direction of rotation
The following input devices can be
evaluated:
Incremental encoders (TTL and Sin-
Cos)
Proximity switches
The following can be configured in the
PNOZmulti Configurator:
Maximum of 4 PNOZ ms1p speed
monitors
Maximum of 2 independent axes
per speed monitor
Logic elements for press applications
Press-related logic elements are designed
for applications on mechanical
presses.
All the functions required for a press
are available.
These include:
Operating modes
Set-up mode
Single stroke
Automatic
Monitoring a rotary cam arrangement
Run monitoring
Monitoring electrosensitive protective
equipment (pulse mode)
Driving and monitoring a press
safety valve
For applications on presses (PNOZ
m2p only), please refer to the chapter
on “Safety solutions for presses” in the
configuration guide “PNOZmulti –
Special applications”. It contains safely
guidelines and a detailed example.
Time elements
Due to the cyclical processing, delay
times on time elements may be up to
15 ms longer than the configured value.
Muting
The muting logic element is used to
temporarily suspend the safety functions
(ESPE/AOPD) without interrupting
the process (muting).
For a limited period of time, and for a
specific operational phase (e.g. when
feeding materials), it will suspend the
effect of safety devices during the
working process. Once completed, it
will reset the safety function.
Performance features:
Muting via light beam devices or
limit switches
Selectable: sequential, parallel or
cross muting
Ability to override the muting function
if a fault occurs
Max. muting time can be set
Time monitoring of the muting sensors
Suspension of bounce time
Operating modes:
Sequential muting
Parallel muting
Cross muting
The muting application is described in
detail in the configuration guide under
“Special applications”.
