For the pressurization control, see the chart below.
J10 PID Control (Anti reset windup
J10 suppresses overshoot in control with the PID processor. As long as the deviation between the feedback and the PID
command is beyond the preset range, the integrator holds its value and does not perform integration operation.
- Data setting range: 0 to 200 (%)
J11 to J13 PID Control (Select alarm output, Upper level alarm (AH) and Lower level alarm (AL))
The inverter can output two types of alarm signals (absolute-value and deviation alarms) associated with PID control if
the digital output signal
PID-ALM is assigned to any of the programmable, output terminals with any of E20 through
E24 and E27 (data = 42).
J11 specifies the alarm output types. J12 and J13 specify the upper and lower limits for alarms.
Select alarm output (J11)
J11 specifies one of the following alarms available.
Data for J11 Alarm Description
0 Absolute-value alarm While PV < AL or AH < PV, PID-ALM is ON.
1 Absolute-value alarm (with Hold) Same as above (with Hold)
2 Absolute-value alarm (with Latch) Same as above (with Latch)
3 Absolute-value alarm (with Hold and
Latch)
Same as above (with Hold and Latch)
4 Deviation alarm While PV < SV - AL or SV + AH < PV, PID-ALM is ON.
5 Deviation alarm (with Hold) Same as above (with Hold)
6 Deviation alarm (with Latch) Same as above (with Latch)
7 Deviation alarm (with Hold and Latch) Same as above (with Hold and Latch)
SV: PID process command PV: PID feedback amount
