The setpoint values are limited to the value set here. If the actual position value exceeds the set
value, the error message "E14.7 maximum position exceeded" is triggered. Position monitoring is
disabled if the value is set to "0".
Positioning with incremental encoders:
The position monitoring function with switch-off in case of error is only active with referenced
incremental encoders, i.e.: in parameter P604 (encoder type), setting {0} or {3} a "reference point
run" or "reset position" is required every time the frequency inverter is switched on.
In contrast, with setting {2} and {4} initial referencing after commissioning is sufficient to activate
the function. Switching the inverter off does not automatically disable the monitoring functionality.
Special case for round axes (modulo axes):
If the functions "Absolute Increment", "Absolute Increment with Saving" or "Path Optimised" are
selected in parameter p604 (encoder type) the value of the overflow point must be set in this
parameter.

The setpoint values are limited to the value set here. If the actual position value undershoots the
set value, the error message "E14.8 minimum position exceeded" is triggered. The position
monitoring is disabled if the value is set to "0".

Difference between switch-on and switch-off point to prevent oscillation of the output signal.
Relevant for functions 20 - 26 of relays 1 and 2 or outputs DOUT 1 to DOUT 2 as well as the
Bus IO Out Bits.
NOTE:
The standardisation parameters (P435, (P442, P451, P456) and P482) and
hysteresis parameters (P436, (P443, P452, P457) and P483) assigned to the relays
or outputs as well as the BusIO Out Bits are not active for POSICON-relevant
functions (20 - 26, see parameterisation function of output P434, (P441, P450,
P455) and P481.
