(2) Setting Time Unit
5-2 Time unit setting screen
To 5-0 screen
Initial value:
Setting range:
(HM)/
(MS)
A unit of time used in various items, such as step signal and step
time, is set.
stands for "~hours~minutes" and
for "~minutes~seconds."
A set unit is unable to be changed during RUN in the PROG mode.
(3) Setting With/Without Power Failure Compensation
5-3 With/without power failure compensation setting screen
To 5-0 screen
Initial value: OFF
Setting range: ON/OFF
When OFF is set, the instrument starts up in the state of RST in
the PROG mode when power is applied again, that is, a state
preceding the power failure is not maintained. When ON is
selected, the instrument starts up in a state preceding the power
failure. (In the FIX mode, a state preceding the power failure is
always maintained.)
The following are excluded, however:
࣭
AT in execution.
࣭
A change in the state of DI input (Power supply is interrupted
in the state of ON, turned OFF during interruption).
࣭
PID No. where hysteresis of zone PID is involved.
(4) Setting Input Abnormality Mode
5-4 Input abnormality mode setting screen
To 5-0 screen
Initial value:
Setting range:
(HLD)
,
(RUN)
,
(RST)
How to deal with sensor break or scaleover, which may occur in
the process of program control, is set.
㸸
The HLD state precedes recovery from scaleover or
resetting. Output is fixed to 0%. If the sensor has
no problem, the HLD state is released upon
applying power again.
㸸
Program action continues until the program ends or
reset is input. (Time continuation) Output is fixed
to 0%.
: Program action is released and the instrument is put
in the state of reset.
(5) Setting Measuring Range Code
5-5 Measuring range code setting screen
To 5-0 screen
Initial value: 05
Setting range: 01 ~ 92
A measuring range is set. A table of measuring range codes is
shown in "5-11. Measuring Range Code Table." A set code is
unable to be changed during RUN in the PROG mode.
(6) Setting Input Unit
5-6 Screen for changing set input unit
To 5-0 screen
Initial value:
Setting range:
/
The unit for sensor input display is selected between
(˚C) and
(˚F). The screen is not displayed when linear input (mV, V,
mA) is selected. A set unit is unable to be changed during RUN
in the PROG mode.
(7) Setting Input Scaling
5-7 Input scaling lower limit value setting screen
To 5-0 screen
Initial value: 0.0
Setting range: –1999 ~ 9989 digits
A lower limit value of scaling for linear input (mV, V, mA) is set.
During sensor input, the lower limit of measuring range is
displayed and no change is possible. A set value is unable to be
changed during RUN in the PROG mode.
To 5-8 screen
5-8 Input scaling higher limit value setting screen
To 5-0 screen
Initial value: 100.0
Setting range: (Input scale) lower limit value + 10 ~
Lower limit value + 5000 digits
A higher limit value of scaling for linear input (mV, V, mA) is
set. During sensor input, the higher limit of measuring range is
displayed and no change is possible. A set value is unable to be
changed during RUN in the PROG mode.
Note
: If a lower limit value is set so as to have a difference
of less than 10 counts or more than 5000 counts from a
higher limit value, the higher limit value is forcibly
changed to the lower limit value +10 counts or the
lower limit value +5000.
5-9 Input scaling decimal point position setting
To 5-0 screen
Initial value: 0.0
Setting range: Without decimal point (0) ~ 3 decimal
places (0.000)
The position of decimal point for input scaling is set. During
sensor input, the screen is for monitoring only and no setting is
possible. A set position is unable to be changed during RUN in
the PROG mode.
(8) Setting PV Bias
5-10 PV Bias setting screen
To 5-0 screen
Initial value: 0.0
Setting range: –1999 ~ 2000 digits
PV bias is used to correct an error of input from sensor or the
like. When a bias is set, control is also carried out with a
corrected value.
(9) Setting PV Filter
5-11 PV filter setting screen
To 5-0 screen
Initial value: 0
Setting range: 0 ~ 100 seconds
In case input changes conspicuously or noise continues, PV filter
is used to mitigate such undesirable effect. When 0 second is set,
filter does not function.
(10) Setting Output Control Characteristic
5-12 Output control characteristic setting screen
To 5-0 screen
Initial value:
|
Setting range:
|
5$ࠊ
|
'$
A characteristic of control output is set. RA is for heating and
DA cooling.
(11) Setting Proportional Cycle
5-13 Proportional cycle setting screen
To 5-0 screen
Initial value: Y output: 30, P output: 3
Setting range: 1 ~ 120 seconds
Proportional cycling time of control output is set. This screen is
not displayed in the case of voltage or current output. For details
of proportional cycle, see
"6-8. Proportional Cycle Time."
(12) Setting SV Limiter
5-14 SV limiter lower limit value setting screen
To 5-0 screen
Initial value: Lower limit value of measuring range
Setting range: Lower limit value of measuring range ~
Higher limit –1 count
When a narrower range than the measuring range is used for
target value setting, a lower limit value is set. (It prevents
erroneous setting in a dangerous range.)
