Current pulse-start
Current pulse-start function enables when regular starting routines are not enough to
accelerate the motor. The most common reason can be pump waxing or
sedimentation. The function produces a series of thrusts to the pump impeller by
sending short high-current impulses.
You can adjust speed, magnitude and frequency of thrusts applied. After the Current
pulse-start routine is competed, the control is given to Kick-start function (if enabled)
and then proceed to production speed with additional help of the acceleration
assistance (if enabled).
