83
Terminal RP
Set E5-00 to 2 (PID target)
Parameter b5-18
Set b5-17 to 1, and input the PID target to b5-18.
Lowest
Modbus Register
Set bit 1 in Modbus register 000FH to 1 (PID target
input) and input the target to 0006H.
Note: When both terminal A1 and A2 are set to 9 (PID Target), oPE07 fault will be triggered.
■ PID Feedback Input Methods
There are two input methods. The first is to input one feedback signal for normal PID control.
The second is to input two signals to control the deviation in between.
Normal PID Feedback:
Selects the PID feedback signal in the source listed in Table 6.7.
Table 6.7 PID Feedback Sources

PID Feedback Source
Setting
Higher
Terminal A1
Set E3-01 to 8 (PID feedback)
Terminal A2
Set E3-07 to 8 (PID feedback)
Lower
Terminal RP
Set E5-00 to 1 (PID feedback)
Note: A1, A2 if the same is set to 8 (PID feedback value), OPE07 (AI parameter setting error) fault will be triggered.
■
PID Differential Feedback
Selects the second PID feedback signal used for deviation calculation in Table 6.8. Assigning a
differential feedback input will automatically activate the differential feedback function.
Table 6.8 PID Differential Feedback Sources
PID Differential Feedback Source
Settings
Terminal A1
Set E3-01 to 10 (differential feedback)
Terminal A2
Set E3-07 to 10 (differential feedback)
Note: When more than one PID feedback differential input source is assigned, oPE07 fault will be triggered.
