NOTE!
These parameters will be viewed according to the selection of the parameters for the SoftPLC
engineering unit (P510 and P511).
P916 – PID Controller Process Variable
Adjustable
Range:
-99.99 a 99.99 [SoftPLC Eng. Un.] Factory
Setting:
-
Properties:
ro
Description:
Read-only parameter which presents the value of the PID controller process variable according to the source
defined in P921 and scale defined in P922 and P923.
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 = [ValueAI(%) x (P923 - P922)] + [P922]
P917 – PID Controller Output
Adjustable
Range:
0.0 to 100.0 %
Factory
Setting:
-
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
Adjustable
Range:
0.0 to 400.0 Hz Factory
Setting:
0.0 Hz
Properties:
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
Adjustable
Range:
0000h to FFFFh Factory
Setting:
-
Properties: ro
Description:
This parameter allows monitoring the logical status of the PID controller application. Each bit represents a state.
