Table 63. PI Controller (Cont.).
PI dead band
P7.1.7 b
Minimum value: -99999.99 varies
Description: PI dead band around setpoint in process units. This is the band where no actions occur to prevent oscillation or repeated activation/
deactivation of controller. The PI output is locked if the feedback stays within the dead band area.
PI dead band delay
P7.1.8 b
0.00 s
Minimum value:
Description: If the PI process value goes out of the dead band area for the desired time delay, at that point the controller will re-initialize and try to
level out again.
PI ramp time
P7.1.9 b
Minimum value: 0.00 s
Defines the rising and falling ramp times for changes in the process value.
Description:
Parameter value can only be changed after the drive has stopped.
a
Parameter value will be set to be default when changing macros.

Table 64. Setpoint (Cont.).
P7.2.1 - Standard.
PI keypad setpoint 1
P7.2.1.1 b
Minimum value: PI Process Unit Min
Description: Keypad PI reference value setpoint 1.
PI keypad setpoint 2
P7.2.1.2 b
PI Process Unit Min
Minimum value:
Description: Keypad PI reference value setpoint 2.
PI wake-up action
P7.2.1.3 b
Minimum value: N.A.
0 = Wake-up when below wake-up level.
Options:
1 = Wake-up when above wake-up-level.
2 = Wake-up when below wake-up level % from PI setpoint.
3 = Wake-up when above wake-up level %from PI setpoint.
Description: This parameter defines the wake-up function action.
P7.2.2 - Setpoint 1.
PI setpoint 1 source
P7.2.2.1 a
Minimum value: N.A.
0 = Not used;
Options:
1 = PI keypad setpoint 1;
2 = PI keypad setpoint 2;
3 = AI;
4 = Drive reference pot;
5 = FB process data input 1;
6 = FB process data input 2;
7 = FB process data input 3;
8 = FB process data input 4;
9 = FB process data input 5;
10 = FB process data input 6;
11 = FB process data input 7;
12 = FB process data input 8;
13 = FB PI setpoint 1; or
14 = FB PI setpoint 2.
Description: Defines source of the setpoint value the drive uses. This can either be an internal preset value, keypad setpoint, analog signal, or
fieldbus message.
