Parameters 317
40.30 Set 1 setpoint
freeze enable
Freezes, or defines a source that can be used to freeze, the
setpoint of the process PID controller. This feature is useful
when the reference is based on a process feedback
connected to an analog input, and the sensor must be
serviced without stopping the process.
1 = Process PID controller setpoint frozen
See also parameter 40.38 Set 1 output freeze enable.
Not selected
Not selected Process PID controller setpoint not frozen. 0
Selected Process PID controller setpoint frozen. 1
DI1 Digital input DI1 (10.02 DI delayed status, bit 0). 2
DI2 Digital input DI2 (10.02 DI delayed status, bit 1). 3
DI3 Digital input DI3 (10.02 DI delayed status, bit 2). 4
DI4 Digital input DI4 (10.02 DI delayed status, bit 3). 5
DI5 Digital input DI5 (10.02 DI delayed status, bit 4). 6
DI6 Digital input DI6 (10.02 DI delayed status, bit 5). 7
DIO1 Digital input/output DIO1 (11.02 DIO delayed status, bit 0). 10
DIO2 Digital input/output DIO2 (11.02 DIO delayed status, bit 1). 11
Other [bit] Source selection (see Terms and abbreviations on page 114). -
40.31 Set 1 deviation
inversion
Inverts the input of the process PID controller.
0 = Deviation not inverted (Deviation = Setpoint - Feedback)
1 = Deviation inverted (Deviation = Feedback - Setpoint)
See also section Sleep function for process PID control (page
67).

40.32 Set 1 gain Defines the gain for the process PID controller. See parameter
40.33 Set 1 integration time.
