Control Period Setting
It is possible to set the control period within a range of 1 to 99 s. The control peri-
od is the period required by the E5
J to turn ON and OFF its relay output or volt-
age output. The ON period increases in proportion to the output value. If the con-
trol period is short, smooth control operation will be possible although a short
control period shortens the life of the relay if relay output is used. Therefore, the
control period should not be less than 20 s if relay output is used. The following
are output examples with an output value of 50.0 %.

When an input shift value is set, the process value will be the input value added
with the shift value.

After the input shift value is set, the it is effective even if the input shift value dis-

It is possible to set the heater current value within a range of 0.0 to 55.0 A. If the
current value exceeds 55.0 A,

will be displayed on the set value display.
The heater current will be processed and displayed if the control output is ON.
It is possible to set the heater burnout alarm value within a range of 0.0 to 50.0 A,
which will be used to detect heater burnout. If the heater burnout alarm value is
set to 0.0 A, the heater burnout alarm output will be always OFF. If the heater
burnout alarm value is set to 50.0 A, the heater burnout alarm output will be al-
ways ON. Refer to
Section 8 Heater Burnout Detection for details.
When the E5
J is in advanced PID with fuzzy self-tuning mode, the following
parameters (
p
,
i
,
d
,
ofr
) will not be displayed (i.e., there is no need to set the
following parameters). The fuzzy self-tuning always adjusts the PID constants to
the most suitable values according to the characteristics of the controlled de-
vice.
