Overview
Position proportional type
The position proportional type only uses standard control.
• Floating control and closed control can also be selected for the
position proportional type. Floating control allows position propor-
tional control without a potentiometer.
● Control / Transfer
output allocation
Use this setting to assign what type of data is output from each output.
For the multi-point input type, assignment data can be set for channels
2 and higher as needed for the number of channels.
When used for control output, assignments are made automatically
based on the control mode setting as explained on the previous page.
No changes are necessary.

Description
Direct action
(cooling)
Control whereby the MV is increased as the
present value increases
(When the present value (PV) is higher than
the set point (SP), the MV is increased in pro-
portion to the difference between the PV and
the SP.)
Reverse action
(heating)
Control whereby the MV is decreased as the
present value increases
(When the present value (PV) is lower than
the set point (SP), the MV is increased in pro-
portion to the difference between the PV and
the SP.)
