In Estimating-type position proportional control, the limiter function
does not work on output operation.
The reverse-signal relay turns on when being limited by low limit.
The direct-signal relay turns on when being limited by high limit.

For the model with optional suffix code /DR:
Remote input with direct input
(E1-terminal area) can be used
when suffix code: Type 2 = 1 or 4,
and with optional suffix code /DR.
However, DI16 is to be deleted.
Program pattern selection
DI41 to DI45 are equipped when suffix
code: Type 2 = 0, 1 or 3.
The function is assigned to each DIs at
factory default.
