AC80T Tower Crane Purpose VFD Manual
Two modes: line ACC/ DEC, S curve ACC/ DEC.;
Four sets ACC/ DEC, time unit: 0.01s, maximum: 650.00s.
Auto voltage regulation for keeping output voltage stable when
grid voltage fluctuation.
Auto current limit during running mode to avoid trip occurs
frequently.
Achieve continuous running through bus voltage control, when
momentary power loss.
