Specialized functionsAnti-swing functionPrevents large-scale swings of the load during acceleration or deceleration, thereby avoiding accidents.
Anti-slack rope protectionEnables the frequency converter to speed up the lifting tool slowly for smooth ascent based on the detection of a heavy load
Hook slip protectionDetects whether the heavy load is slipping and issues an alarm after the brake engages, thereby causing the motor to hover
Brake controlControls the engagement and disengagement of the brake device based on factors such as frequency and current, to prevent unexpected slipping
Operating rod zero-return detectionDetermines whether the operating rod is in the neutral position
Reverse control of commandsSupports either engaging the brake to halt during forward and reverse rotation switching, or continuing directly to the reverse frequency without engaging the brake, when brake control is active
Acceleration and deceleration switchingSupports up to three frequency switching points and the adjustment of acceleration time and deceleration time
Deceleration limitSupports simple positioning, automatically optimizing deceleration time
Voltage suppressionAutomatically adjusts the frequency to stabilize the bus voltage, preventing fault reports
Overload protectionPrevents equipment damage due to excessive load
Low-speed operation protectionPrimarily protects machines that should not operate at low speeds for a long time
Load-dependent speed regulatingAutomatically adjusts the operating speed based on load changes, raising work efficiency
Macro parametersSelects different hoisting macros based on the on-site application scenario and hoisting mechanism.
