Table 30. Setpoint (Cont.).
P7.2.2.2
ab
PI setpoint 1 sleep enable
ID 1315
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Disabled; or
1 = Enabled.
Description:
This function will disable the output when the frequency drops below the sleep frequency for the sleep delay time. The output
re-engages when feedback rises above the wake-up level.
P7.2.2.3
b
PI setpoint 1 sleep delay
ID 1317
Minimum value:
0 s
Maximum value:
3,000 s
Default value:
0 s
Description:
This parameter sets the delay time after the setpoint drops below the sleep level for this amount of time and then the drives output will
shut off till the wake up level is met. It is to prevent large fluctuations when going into the sleep function to save motor run time.
P7.2.2.4
b
PI setpoint 1 wake-up level
ID 1318
Minimum value:
-99999.99 varies
Maximum value:
99999.99 varies
Default value:
0.00 varies
Description:
Defines the level for the PI feedback value to go above top enable the PI output to be re enabled. This value is based of the % of
feedback which can be scaled based off the PI unit min./max, values.
P7.2.2.5
b
PI setpoint 1 boost
ID 1320
Minimum value:
-2.00 varies
Maximum value:
2.00 varies
Default value:
1.00 varies
Description:
The setpoint can be boosted via a multiplier value.
P7.2.2.6
b
PI setpoint 1 sleep level
ID 2450
Minimum value:
Min Freq
Maximum value:
Max Freq
Default value:
0.00 Hz
Description:
Defines the level of which the unit value is used to look at to go into the sleep mode. When the unit drops below this level for the sleep
delay time, it will put the drive into the sleep mode.
P7.2.2.7
b
SP1 sleep mode over cycle time
ID 1842
Minimum value:
0
Maximum value:
10
Default value:
0
Description:
Defines the count the drive come in and out of sleep mode. If multiple times done in this time frame, the drive would trip on ”pump over
cycle” fault.
One cycle is defined when the drive transfers from normal mode to sleep mode.
0 value means do not do the sleep over cycle check and clear ”pump over cycle” fault.
P7.2.2.8
b
SP1 sleep mode maximum cycle time
ID 1843
Minimum value:
0
Maximum value:
3,600
Default value:
0
Description:
Defines the maximum time for sleep over cycle checking.
P7.2.3 - Setpoint 2.
P7.2.3.1
ab
PI setpoint 2 source
ID 1321
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
1
Options:
0 = Not used;
1 = PI keypad setpoint 1;
2 = PI keypad setpoint 2;
3 = AI;
4 = Drive reference pot;
5 = Fieldbus process data input 1;
6 = Fieldbus process data input 2;
7 = Fieldbus process data input 3;
8 = Fieldbus process data input 4;
9 = Fieldbus process data input 5;
10 = Fieldbus process data input 6;
11 = Fieldbus process data input 7;
12 = Fieldbus process data input 8;
13 = Fieldbus PI setpoint 1; or
14 = Fieldbus 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.
