Table 67. Pump parameters (Cont.).
P9.2.4
ab
Back spin delay
ID 2423
Minimum value:
0 s
Maximum value:
32,500 s
Default value:
0 s
Description:
Run delay time parameter sets the time required for the drive to wait before another run command can be received. During this time,
the run signal is given. It is ignored until the time has expired upon which it will then start. This is true for keypad, I/O, or Fieldbus
Control places.
P9.2.5
ab
Minimum run time
ID 1813
Minimum value:
0 s
Maximum value:
32,500 s
Default value:
0 s
Description:
Drive minimum run time.
P9.2.6
b
Minimum frequency ramp time
ID 1850
Minimum value:
0.1 s
Maximum value:
2,000.0 s
Default value:
10.0 s
Description:
Ramp time for output to minimum frequency.
P9.3 - Multi-pump multi-drive (*DM1 PRO).
P9.3.1
ab
Multi-pump mode
ID 2279
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Disabled or
1 = Multi-drive network.
Description:
Determines the number of drives being used in the multi-pump configuration:
0 = Disabled - single drive for motor; or
1 = Multi-drive - multi-follower sequence with multiple drives.
P9.3.2
ab
Number of drives
ID 2449
Minimum value:
1
Maximum value:
5
Default value:
1
Description:
This defines the number of drives active when doing the multi-drive pump and fan scheme. By default, there will be always one drive
active at one time. By setting value to above one, it allows for bringing in additional drives to maintain the sytem.
P9.3.3
ab
Drive ID
ID 2278
Minimum value:
0
Maximum value:
5
Default value:
0
Description:
This parameter defines the drive address when using mult- drive pump mode. Based off this ID, the drive enables in the desired
sequence and can be monitored at this drive ID value in the monitor screen.
P9.3.4
ab
Regulation source
ID 2284
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Network only; or
1 = PI controller.
Description:
For drives that have been connected with both start/stop signal and PI feedback - can be set up as "Feedback", so they will have ability

b
PI bandwidth
ID 2458
Minimum value:
0.00 varies
Maximum value:
6,000.00 varies
Default value:
10.00 varies

ID 2315
Minimum value:
MinFreq
Maximum value:
400.00
Default value:
50.00
Description:
Output frequency is above stagging frequency and PI error is out of PI bandwidth - motor should add to system.
P9.3.7
ab
De-staging frequency
ID 2316
Minimum value:
0.00
Maximum value:
MaxFreq
Default value:
0.00
Description:
Output frequency is below de-stagging frequency and PI error is out of PI bandwidth - motor should remove from system.
P9.3.8
b
Add/remove delay
ID 344
Minimum value:
0 s
Maximum value:
3,600 s
Default value:
