4.0% / real32Defines the speed reference used to perform current
pulse-start routine. The base value to calculate the
current pulse speed reference is parameter 99.9 Motor
nominal speed.

100.0% / real32Defines the motor current reference used for producing
a thrust to the pump impeller.
This is active only for the time defined with parameter
75.69 Current pulse cycle time. This can be repeated as
many times as set in parameter 75.68 Current pulse nr
of cycles.
The base value to calculate the current pulse start
reference is parameter 99.6 Motor nominal current.

- / real32Defines the quantity of desired current pulses applied
in sequence.
Each cycle consists of a period of thrust generated by
high motor current set in parameter 75.62 Current pulse
start current ref and a period of waiting together
lasting as long as set in parameter 75.69 Current pulse
cycle time.
