Description
Sets the speed of the Pump cleaning reverse.
It should be set to the maximum speed, which
is 33% or the nominal motor speed.
Sets the torque for Pump cleaning reverse. It
should be set to the highest possible, which is
100%.
Complete list 08 Sequence
u u
Description
Enables sequence start of motors which is
necessary to have different starts for normal
soft start of pump and Pump cleaning
forward start.
Sets the nominal current for the motor. For
good performance, it is important that the
nominal current is set to the correct value.
For Inside Delta connection, this parameter
shall be set to 58% of the nominal motor
current.
Sets the desired start mode for Pump
cleaning forward. For maximum effect during
the start select full voltage start.
