Dedicated features

Anti-shake function

Prevents accidents caused by large swings of the load during acceleration or deceleration

Anti-loose rope protection

Accelerate slowly and rise smoothly according to whether the weight is lifted

Hook protection

After holding the gate, it detects whether the heavy object is hooked, and an alarm is issued, and the motor hovers

Holding the brake control

Control the brake holding device and loosening the brake through the judgment of frequency, current, etc., to avoid accidents such as slipping

Joystick zeroing detection

Determine whether the joystick is in neutral or not

Command reverse control

When the brake control is effective, it supports holding the brake to stop during the forward and reverse switching process, or running directly to the reversal frequency without holding the brake

Accelerate and deceleration switching

Support 3 frequency switching points to switch acceleration and deceleration time

Deceleration limit

Realize simple positioning function, automatic optimization of deceleration time

Voltage suppression

Automatically change the frequency to stabilize the bus voltage to prevent fault reporting

Overload protection

Prevents excessive loads from damaging the equipment

Low-speed operation protection

The main application is not suitable for machines that run at low speed for a long time

Load as you go

Automatically adjust the operating speed according to load changes to improve work efficiency

Macro parameters

According to the on-site application scenario, different lifting mechanisms choose different lifting macros

Basic features:

acceleration and deceleration curves

Master-slave control

It can realize the master-slave synchronous control function of two or more motors

Automatic voltage adjustment

When the grid voltage changes within a certain range, it can automatically keep the output voltage constant

Multi-motor switching

Four sets of motor parameters, which can realize the switching control of four motors

Overvoltage and overcurrent stall control

Automatic current and voltage limit during operation to prevent frequent overcurrent and overvoltage tripping

Power outage and restart

After the frequency converter is powered off, when it is powered on again, it will automatically run after the set time is reached
