Page: 301 / 514

Parameters 301
DI6 Digital input DI6 ( 10.02 DI delayed status , bit 5). 7
Timed function 1 Bit 0 of 34.01 Timed functions status (see page 273 ). 18
Timed function 2 Bit 1 of 34.01 Timed functions status (see page 273 ). 19
Timed function 3 Bit 2 of 34.01 Timed functions status (see page 273 ). 20
Supervision 1 Bit 0 of 32.01 Supervision status (see page 266 ). 21
Supervision 2 Bit 1 of 32.01 Supervision status (see page 266 ). 22

Other [bit] Source selection (see Terms and abbreviations on page 162 ). -
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)

Sleep and boost functions for process PID
control (page 52 ).
Not inverted
(Ref - Fbk)
Not inverted
(Ref - Fbk) 0. 0
Inverted (Fbk - Ref) 1. 1

40.32 Set 1 gain Defines the gain for the process PID controller. See
parameter
40.33 Set 1 integration time .
1.00
0.01…100.00 Gain for PID controller. 100 = 1
40.33 Set 1 integration
time Defines the integration time for the process PID controller.
This time needs to be set to the same order of magnitude as
the reaction time of the process being controlled, otherwise
instability will result.
Note: Setting this value to 0 disables the “I” part, turning the
PID controller into a PD controller.
