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.
In Manual operation, the relay turns on while the
or key is pressed. Output limiter does not work.

Input ladder calculation program (signal goes to the control computation as is when without ladder program). For ladder program, see the LL50A Parameter Setting Software User’s Manual.
Output ladder calculation program (signal goes to the output as is when without ladder program). For ladder program, see the LL50A Parameter Setting Software User’s Manual.

OFF) at FAIL of Loop-1 controller
Position Proportional Computation Output cannot be calculated by ladder program.
Universal input (E1-terminal area) can be used
when UT55A/UT52A optional suffix code /U1.
However, DI16 does not exist.
(For Standard model)
Cascade input can be used when UT55A suffix code: Type
2 = 1, 2, 4, 5, or 7; UT52A suffix code: Type 2 = 1 or 2.
(For Detailed model)
Cascade input can be used when UT55A/UT52A optional
suffix code /R1 or /RCH1.
(For Standard model)
DI16 is equipped when UT55A suffix code: Type 2 = 1, 2,
4, 5, or 7; UT52A suffix code: Type 2 = 1 or 2.
(For Detailed model)
DI16 is equipped when UT55A/UT52A optional suffix code
/R1 or /RCH1.
