PID REF DEC TIME
0.0 … 1800.0 s 1 = 0.1 s 0.0 s
Defines the time for the reference (PID setpoint) decrease from 100 to 0%.
4034
PID REF FREEZE
NOT SEL
Freezes the input (reference, PID setpoint) of the process PID controller.
0 = NOT SEL – Not selected
1 = DI1 – Reference is frozen on the rising edge of digital input DI1.
2 = DI2 – See selection DI1.
3 = DI3 – See selection DI1.
4 = DI4 – See selection DI1.
5 = DI5 – See selection DI1.
-1 = DI1(INV) – Reference is frozen on the falling edge of digital input DI1.
-2 = DI2(INV) – See selection DI1(INV).
-3 = DI3(INV) – See selection DI1(INV).
-4 = DI4(INV) – See selection DI1(INV).
-5 = DI5(INV) – See selection DI1(INV).
4035
PID OUT FREEZE
NOT SEL
Freezes the output of the process PID controller.
0 = NOT SEL – Not selected
1 = DI1 – Output is frozen on the rising edge of digital input DI1
2 = DI2 – See selection DI1.
3 = DI3 – See selection DI1.
4 = DI4 – See selection DI1.
5 = DI5 – See selection DI1.
-1 = DI1(INV) – Output is frozen on the falling edge of digital input DI1.
-2 = DI2(INV) – See selection DI1(INV).
-3 = DI3(INV) – See selection DI1(INV).
-4 = DI4(INV) – See selection DI1(INV).
-5 = DI5(INV) – See selection DI1(INV).

INTERNAL SETPNT2
-3276.8 … 3276.7 - -
Selects a constant value as the process PID controller reference, which becomes
active when parameter 4010 SET POINT SEL value is set to INTERNAL and setpoint
2 is selected with the input defined by parameter 4039 INT SETPNT SEL. Value in
percent.
4037
INTERNAL SETPNT3
-3276.8 … 3276.7 - -
Selects a constant value as the process PID controller reference, which becomes
active when parameter 4010 SET POINT SEL value is set to INTERNAL and setpoint
3 is selected with the input defined by parameter 4039 INT SETPNT SEL. Value in
percent.
4038
INTERNAL SETPNT4
-3276.8 … 3276.7 - -
Selects a constant value as the process PID controller reference, which becomes
active when parameter 4010 SET POINT SEL value is set to INTERNAL and setpoint
4 is selected with the input defined by parameter 4039 INT SETPNT SEL. Value in
percent.
