NARROW PROPORTIONAL CONSTANT
This lets you vary the unit's proportional constant in the low frequency range
(start-up constant).
AMPLITUDE FOR INCREASING THE KE CONSTANT
This lets you vary the amplitude of the step used to increase the KE constant.
WIDE PROPORTIONAL CONSTANT
This lets you vary the unit's proportional constant in the high frequency range
(working constant).
AMPLITUDE FOR INCREASING THE KA CONSTANT
This lets you vary the amplitude of the step used to increase the KA constant.
PWM FREQUENCY (Pulse Width Modulation)
Allows the variation of the internal module switching tasks.
A high-pitched sound will be heard from the motor (depending on the type of
motor) when the switching frequency is varied.
CALCULATION FACTOR FOR DRY RUN STOP
During the installation of the unit, it is advisable to test the dry run stop by closing
the intake valve of each pump. If no error occurs, increase this value by intervals
of 5% and repeat the test.
