Specialized functions

Anti-swing function

Prevents large-scale swings of the load during acceleration or deceleration, thereby avoiding accidents.

Anti-slack rope protection

Enables the frequency converter to speed up the lifting tool slowly for smooth ascent based on the detection of a heavy load

Hook slip protection

Detects whether the heavy load is slipping and issues an alarm after the brake engages, thereby causing the motor to hover

Brake control

Controls the engagement and disengagement of the brake device based on factors such as frequency and current, to prevent unexpected slipping

Operating rod zero-return detection

Determines whether the operating rod is in the neutral position

Reverse control of commands

Supports 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 switching

Supports up to three frequency switching points and the adjustment of acceleration time and deceleration time

Deceleration limit

Supports simple positioning, automatically optimizing deceleration time

Voltage suppression

Automatically adjusts the frequency to stabilize the bus voltage, preventing fault reports

Overload protection

Prevents equipment damage due to excessive load

Low-speed operation protection

Primarily protects machines that should not operate at low speeds for a long time

Load-dependent speed regulating

Automatically adjusts the operating speed based on load changes, raising work efficiency

Macro parameters

Selects different hoisting macros based on the on-site application scenario and hoisting mechanism.

Basic functions

Straight line, S-shaped curve

Simple PLC and multiple speeds

Master-slave control

Automatic voltage regulation (AVR)

Constant output voltage when the grid voltage changes within a certain range

Multi-motor switching

Four groups of motor parameters available to control the switching of four motors

Overvoltage and overcurrent stall control

Automatically limits the current and voltage during operation, to prevent frequent trips caused by overcurrent or overvoltage

Automatic restart after a power failure

Enables the frequency converter to automatically resume operation when the set time is reached, after the frequency converter undergoes a power failure and restoration

Fast current limit

Prevents frequent faults on the frequency converter caused by overcurrent
