Parameters 259
78.04
Autochg level
Speed limit for the Autochange function when parameter
is set to
.
This parameter is only valid in traditional pump control.
The pump starting sequence is changed when the
Autochange interval has elapsed and the drive speed is
below this limit. Autochanging is indicated by a warning on
the control panel display.
Notes:
• The value of this parameter must be within the allowed
range (between minimum and maximum limits).
Otherwise no Autochanging is possible.
• When the drive is powered off, the values of the starting
sequence counter and the Autochange interval counter
are stored. The counters will continue from these values
after the drive is powered on.
Example:
There are three pumps in a system (parameter
is set to 3). Autochange level is set to
1500 rpm.
An Autochange occurs when the drive speed is below 1500
rpm, and the Autochange interval has elapsed since the
previous Autochange. Upon the Autochange,
1. All pumps are stopped
2. The starting sequence is incremented (from 1-2-3 to
2-3-1, etc.)
3. The contactor that controls the speed-regulated pump is
closed
4. The delay set by parameter
passes
5. The speed-regulated pump is energized and normal
operation starts.
If the Autochange level is 0 rpm and the interval has
elapsed, Autochange will occur during a stop (for example,
when the Sleep function is active).
0…32767 rpm
Autochange level.
1 = 1 rpm
78.05
Autochg interval
Specifies the Autochange interval. See parameter
0.00 … 1092.25 h
Autochange interval.
100 = 1 h
78.06
Interlock pump 1
Selects the input (or signal) for status of pump 1.
When the input is 1, the drive assumes the pump is in use
and can be started.
Not used
The interlock is off, meaning that the pump is not in use.
0
On
The interlock is on, meaning that the pump is ready for use.
1
DI1
Digital input DI1 (as indicated by
, bit 0).
1073742337
DI2
Digital input DI2 (as indicated by
, bit 1).
1073807873
DI3
Digital input DI3 (as indicated by
, bit 2).
1073873409
DI4
Digital input DI4 (as indicated by
, bit 3).
1073938945
DI5
Digital input DI5 (as indicated by
, bit 4).
1074004481
Const
Bit pointer setting (see

Pointer
78.07
Interlock pump 2
Selects the input (or signal) for status of pump 2.
When the input is 1, the drive assumes the pump is in use
and can be started.
Not used
The interlock is off, meaning that the pump is not in use.
0
No.
