Defines the speed reference used to perform current
pulse-start routine. The base value to calculate the
current pulse speed reference is parameter
nominal speed.
Current pulse speed reference.
Defines 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
many times as set in parameter
of cycles.
The base value to calculate the current pulse start
reference is parameter
Current pulse start current ref.
Defines 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
start current ref and a period of waiting together
lasting as long as set in parameter
cycle time.
Current pulse number of cycles.
Defines the time for a period in the current pulse-start
routine.
Each cycle consists of two such periods.
Current pulse cycle time.
Defines the pump speed reference.
This parameter is read-only.
Pump speed reference.
Displays the status word of the functions controlling
ESP control program starting routines, i.e. Starting
speed, Acceleration assistance, Kick-start and Current
