Validation cut-off frequency
As implausible signals may arise due to edge jitter on the sensors around the standstill pos-
ition, a validation cut-off frequency must be configured for sensor types with proximity
switches in the PNOZmulti Configurator (edge jitter is caused by the position control of the
drive frequency converter or by external interference signals).
If the value of the validation cut-off frequency falls below the configured value, the feasibility
check of the sensors will no longer be run.
System reaction time
Calculation of the maximum reaction time between an input switching off and a linked out-
put in the system switching off is described in the document "PNOZmulti System
Expansion [
29]".
Proximity switches
} The following proximity switches can be used with a pnp or npn output:
– Inductive
– Capacitive
} The proximity switches must be fitted so that at least one is always activated. In other
words, the proximity switches must be fitted so that the recorded signals always over-
lap.
} The cable used to connect the proximity switches must be shielded (see connection
diagrams in the chapter entitled "EMC-compliant wiring").
} A DC voltage in the range of 0 - 30 V can be monitored via track S. It should be used to
monitor the supply voltage of the proximity switches.
