SIEPCYEUOQ2V01A Q2V Technical Manual
Use
to select how the feedback signal is input to the drive for PID control.
Table 12.14 PID Feedback Input Method
PID Feedback Input Method
Setting Value
MFAI terminal AI1
Set
H3-02 = F [PID Fbk]
.
MFAI terminal AI2
Set
H3-10 = F
.
Pulse train input terminal DI
Set
H6-01 = 1 [PIDFbk Value]
.
•
Use two signals, and use the difference between those signals as the feedback signal.
The drive uses two feedback signals, and the difference between those signals becomes the deviation.
Use
to select how the second feedback value is input to the drive. The drive calculates the deviation
of the second feedback value. Set
H3-02 or H3-10 = 11 [AI1 Function Selection or AI2 Function Selection =
Diff PIDFbk]
to enable the second feedback signal used to calculated the deviation.
Table 12.15 PID Differential Feedback Input Method
PID Differential Feedback Input Method
Setting Value
MFAI terminal AI1
Set
H3-02 = 11 [Diff PIDFbk]
.
MFAI terminal AI2
Set
H3-10 = 11
.
Note:
If you set
H3-02 and H3-10 = 11
, it will trigger
oPE07 [Analog Input Selection Error]
.

PID Feedback Loss Detection
The PID feedback loss detection function detects broken sensors and defective wiring between the drive and
sensors.
