4-13 Using the Transfer Output
4-13-1 Transfer Output Function
• If a control output is a linear current output it can be used as a transfer
output. To use the transfer output, set the “transfer output type” parame-
ter to any setting other than OFF.
(When the “transfer output type” parameter is set to any setting other than
OFF, the “transfer output upper limit” and “transfer output lower limit”
parameters will be enabled.)
Transfer Output Type
Note (1) The default is OFF. If the transfer type is set to OFF, the item assigned in
the “control output 1 assignment” parameter will be output on control out-
put 1.
(2) The difference between the transfer output value and the linear current
output value is illustrated in the following figure.
If the linear output is used as the transfer output when the linear current
output type is set to 4 to 20 mA, 4.0 mA will be output for 0% and 20.0
mA will be output for 100%.
When a linear output is used for the control output, 3.7 mA is output for
0% and 20.3 mA is output for 100% when the control output for heating
is selected to ensure that the control object is controlled at 0% and 100%.
11. Press the U or D key to set the manual MV. (In this example, the MV is
set to 500%.)
Note The manual MV setting must be fixed (see
page 12),
but values
changed with key operations are reflected in the control output
immediately.
Operation Level
12. Press the O key for at least one second to move from the manual control
level to the operation level.
