5.7 H: Terminal Functions
When you set a terminal that is not in use to F, you can use the signal input to the terminal as PLC analog signal input
through MEMOBUS/Modbus communications or the communication option. This input signal does not have an effect
on drive operation. This functions the same as setting 1F (Through Mode).
■
16: Differential PID Feedback
Setting Value Function
16 Differential PID Feedback
The drive uses the deviation between the PID feedback and the differential feedback value signals to calculate the PID
input.
■
1F: Not Used
Setting Value Function
1F Not Used
When you set a terminal that you do not use to 1F, you can use the signal that is input to that terminal as the PLC
analog signal input from MEMOBUS/Modbus communications or the communication option. This input signal does
not have an effect on drive operation. This signal functions the same as F (Through Mode).

2D: Differential Level Source
Setting Value Function
2D Differential Level Source
302
Enters the PID differential feedback value if the full scale analog signal (10 V or 20 mA) is 100%.
Use this setting for unused terminals or to use terminals in through mode.
Enters the PID Feedback Backup signal for the drive to use when it loses the primary PID feedback set for H3-xx = B [PID
Feedback].
Enters the PI2 Control setpoint level as a percentage of the S3-02 [PI2 Control Transducer Scale] value.
Enters the PI2 Control feedback level as a percentage of the S3-02 [PI2 Control Transducer Scale] value.
Enters the PI Auxiliary Control feedback value when YF-01 = 1 [PI Aux Control Selection = Enabled].
This input is the PID Feedback source when Emergency Override is running in PID mode (S6-02 = 2 or 3 [Emergency Override Ref
Selection = System PID Mode or Independent PID Mode]).
This input is the PID Setpoint source when Emergency Override is running in PID mode (S6-02 = 2 or 3 [Emergency Override Ref
Selection = System PID Mode or Independent PID Mode]).
Enters a feedback value to calculate the Differential Level between the Differential Level Source feedback and the primary PID
Feedback [H3-xx = B].
