NOTE!
This parameter will be viewed according to the selection of the parameters for the SoftPLC engineering
unit (P510 and P511).
The conversion of the value read by the analog input in percentage into the value of the process variable shown in
P916 according to the scale is done through the following formula:
P916 = [ValorAI(%) x (P923 - P922)] + [P922]
P917 - PID Controller Output
Range: 0.0 to 100.0 %
Properties: ro
Description:
Read-only parameter which presents, in percentage (%), the value of the PID controller output, where 0.0 %
corresponds to the motor minimum speed (P133), and 100.0 % corresponds to the motor maximum speed
(P134).
P918 - PID Controller Setpoint in Manual Mode
Range: 0.0 to 400.0 Hz
Description:
This parameter defines the value of the PID controller output when it is in the manual mode, that is, when the PID
controller works in manual mode, the value defined as manual setpoint is transferred directly to the PID controller
output.
P919 - PID Controller Logical Status
Range: 0 to FFFF (hexa)
Bit 0 = Sleep Mode Active (A750)
Bit 1 = PID in Manual (0) / Automatic (1)
Bit 2 = PV Low Level (A760)
Bit 3 = PV Low Level (F761)
Bit 4 = PV High Level (A762)
Bit 5 = PV High Level (F763)
Bit 6 to 15 = Reserved
Properties: ro
Description:
This parameter allows monitoring the logical status of the PID controller application. Each bit represents a state.
