10 Internal In0, In1, In2 / 11 External IO 1DI0, 1DI1,
1DI2, 1DI3, 1DI4, 2DI5, 2DI6, 2DI7
Configure the parameters to either Pump cleaning
automatic, Pump cleaning forward or Pump cleaning
backward.
INFORMATION
An Extension I/O module, see chapter 5.1.3
Extension I/O, is necessary if the 11 External IO
is going to be used.
Fieldbus configuration
Fieldbus digital outputs (from PLC to Softstarter) can be
used to run Pump cleaning automatic, Pump cleaning
forward or Pump cleaning backward.
For more information about the communication, see
chapter 8 Communication
Pump cleaning is configured with the following
parameters:
Parameter Description Setting range Default value
29.01 Pump clean reverse speed Sets the slow speed reverse. Fast jog
reverse is 33 %, jog reverse is 20 % and
creep reverse is 9 % of the nominal motor
speed.
Fast jog, Jog, Creep Jog
29.02 Pump clean reverse strength Parameter related to the torque that is
generated during slow speed in the reverse
direction. Choose suitable value for the
application. Too high value could cause
oscillations and if too low the motor may
not start.
10 … 100 % 45 %
29.03 Pump clean forward start mode Sets the desired start mode: Voltage start
ramp = Increases voltage linearly, Torque
start ramp = Increases torque in a pre-
defined pattern, Full Voltage start = Ramps
up to full voltage within one third of a
second

29.04 Pump clean auto forward time Sets the number of seconds to run forward
per sequence for automatic pump cleaning.
1.0 … 100.0 s 5.0 s
29.05 Pump clean auto reverse time Sets the number of seconds to run reverse
per sequence for automatic pump cleaning.
1.0 … 100.0 s 5.0 s
29.06 Pump clean brake strength Sets the pump cleaning braking strength to
10-100 %. Only used for pump cleaning in
forward direction.
10 … 100 % 45 %
29.07 Pump clean brake timeout Sets the motor brake timeout used when
pump cleaning forward has finished.
1.0 … 100.0 s 10.0 s
