Chapter 7. PARAMETER SETUP
●
C50 (auxiliary output lower limit)
●
C51 (auxiliary output upper limit)
• This parameter is the scaling setting for auxiliary output. The values of the
upper limit setting and lower limit setting can also be inverted.
• In the following example, the type is set to MV at auxiliary input. 12 mA is
output when MV is 100% and 20 mA is output when MV is 0%. In the
following figure, MV is 200% when virtually calculated at 4 mA.
Accordingly, the settings of
C50
and
C51
become 200.0 and 0.0, respectively.
●
C65 (time display)
0: Remaining segment time
1: Total operation time
• This parameter selects the time display in the basic display state in the program
operation mode.
• When set to 0, in the READY mode, the time setting value of the currently
selected segment is displayed.
• When set to 0, in the RUN, HOLD, FAST or END modes, the remaining time
for the currently executing segment is displayed after being rounded down.
For example, if the remaining time is 1 hour, 30 minutes, 59 seconds when the
time unit is set to “hours:minutes”, the time display is “
1 .30
”.
• When set to 1, in the READY mode, the time display is “
0 .00
”.
• When set to 1, in the RUN, HOLD, FAST or END modes, the time it takes to
move from the READY to the RUN mode is displayed after being round down.
After “
99.59
” the time display changes to “
0 .00
”.
For example, if the remaining time is 101 hours, 30 minutes, 59 seconds when
the total operation time is set to "hours:minutes", the time display is “
1 .30
”.
• In the FAST mode, the time display changes according to the FAST scale if this
parameter is set to either 0 or 1.
●
C66 (PV display)
This parameter selects PV display in the basic display state. You can select
between numerical display or no display at all. The setting of this parameter does
not influence PV-related input processing, PID operation, event output, auxiliary
output and alarm display.
Also, to eliminate PV alarm display or PV alarm event output, select the
thermocouple range by the input range to short-circuit the input terminals.
