No function
is assigned
to DI3.
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.

Universal input (E1-terminal area) can be used
when UT55A/UT52A optional suffix code /U1.
However, DI16 does not exist.
(For Detailed model)
Remote input can be used when UT55A/UT52A
optional suffix code /R1 or /RCH1.
(For Standard model)
Remote 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)
Feedforward input can be used when
UT55A optional suffix code /A2.
(For Standard model)
Feedforward input can be used when
UT55A suffix code: Type 2 = 7.
(For Detailed model)
DI16 is equipped 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.
