9.6. Parameter Group 8 – Application Function Specific Parameters
Par Name
P8-01 Pump Stir Interval Duration
This parameter can be used to set a pre-defined period of inactivity, whereby if the drive remains in standby mode for a period of time
exceeding the limit, stir function is activated, and the drive will operate at preset speed 7 (P2-07) for the time set in P8-02. This allows
the pump to stir, preventing sediment from settling and avoiding a blockage.
P8-02 Pump Stir Activation Time
Set the time period that the stir function will be active once triggered (excludes time for deceleration to stop).
P8-03 Pump Clean Function Select
This parameter configures the drive conditions that will cause activation of the automatic pump clean function. When activated, the
pump clean will operate the pump at preset speed 5 (P2-05) for the time period set in P8-04, followed by Preset Speed 6 (P2-06)
(Providing P2-06 <> 0) for the time set in P8-04, before resuming normal operation. During the cleaning cycle, the ramp time set in P8-
05 is used for both acceleration and deceleration, and overrides P1-03 and P1-04.
Where possible, P2-05 and P2-06 may be set to negative values, to allow the pump to be reversed. For best results, it is recommended
to use as high a speed as possible, and to adjust P8-05 to allow a short acceleration time whilst avoiding over current trips.
0 : Disabled.
1 : Active on start-up only. The pump cleaning function operates every time the pump is started.
2 : Active on start-up and high current detection. The pump cleaning function operates every time the pump is started,
and also in the event that the drive detects a possible pump blockage during normal operation. This requires the Motor Current Profile
Monitoring function to be active and commissioned for correct operation, see parameter P8-06.
3 : Active on high current detection only. The pump cleaning function operates only when a possible pump blockage is
detected during normal operation. This requires the Motor Current Profile Monitoring function to be active and commissioned for
9
correct operation, see parameter P8-06.
NOTE The pump clean function can also be activated by digital input configured in group 9 parameters.
P8-04 Pump Clean Time
Sets the time period for the operation of the pump cleaning cycle. When bi-directional pump cleaning is selected, the time interval is
used twice, once in each direction.
P8-05 Pump Clean Function Ramp Time
Independent ramp rate used only for the pump automatic cleaning function (see P8-03) when the motor is Accelerated as part of the
cleaning cycle.

Drive Sets the motor magnetising period in V/F Mode.
Sets the motor alignment time in PM modes.
0.0% For PM Motors, applies a torque boost current
at low frequency, % x P1-08.
0.0% For PM motors, determines the frequency, % x
P1-09 when the boost current is removed.
0
When P4-01 = 4 (BLDC control) and P7-19 = 1
(Enable) the drive will reduce the output voltage
during light load operation in order to improve
1
motor efficiency. This setting has no effect if
the motor is driven close to its nominal current,
where the nominal flux level will be applied.
