Setting (Correcting) the Detail Information
• If the data is not set correctly using auto setting, you can set (correct) the items
using the operation keys.
• Select the turning parameters from the following:
Tuning parameter Soft Key Menu (Item ID)
Target setpoint SP
Alarm value 1 A1
Alarm value 2 A2
Alarm value 3 A3
Alarm value 4 A4
Proportional band P
Integral time I
Derivative time D
Output high-limit OH
Output low-limit OL
Manual reset MR
Relay hysteresis H
Control direction DR
Dead band DB
Preset output PO
Others ETC
• If you select an item ID (tuning parameter) from “SP, A1, A2, A3, A4, P, I, D, OH,
OL, MR, H, DR, DB, and PO,” the preset setup information is assigned to the detail
information items (item name, register address, decimal point position, high and
low limits of the value range).
• If the connecting model is UT320, UT321, UT350, UT351, or UT420, you cannot
set the tuning parameter of alarm value 4 (A4).
• When the connecting model is “ETC,” you can only set “ETC” for the tuning
parameter.
• Item ID
Item IDs are used to display the tuning parameters on the setting display of the CX.
A list of tuning parameters and item ID is indicated above.
• Item name
You can set the name of the tuning parameter using up to 6 alphanumeric
characters.
• Registers address
You can set the register address in the following range.
30001 to 39999, 40001 to 49999, 300001 to 365535, 400001 to 465535
• Decimal point
Set the decimal point position in the range of 0 to 4.
•
No decimal point when set to 0.
• One digit to the right of the decimal when set to 1.
• Two digits to the right of the decimal when set to 2.
• Three digits to the right of the decimal when set to 3.
• Four digits to the right of the decimal when set to 4.
• Range lower and upper
• Set the limits in the range of –30000 to 30000.
• The decimal point position above is used. For example, if the decimal point
position is set to “1” and you enter “10000,” it is taken to be “1000.0”.
