The YWK-KW pedal frequency converter is mainly composed of a brake frame, a PED frequency converter, a frequency converter speed control box, a foot controller and an operation control box.

Multiple functions can be combined to meet different working conditions.

The brake function of the brake is realized through two methods: foot control and manual control, and can be converted freely.

The foot controller can control the braking torque and braking time in time; manual control can achieve short-term continuous braking, which can reduce the operating strength during parking braking.

The PEd frequency converter is S3 operating system. In the power outage or shutdown state, the self-locking mechanism can be automatically self-locking and braking (the micromotor is powered by the backup battery); it can also be self-locking or opening by manual control.

The electric wear automatic compensation device has high compensation accuracy, accurate and reliable operation, and a long service life.

The brake frame is suitable for horizontal installation and can be designed according to the box installation structure of the slewing mechanism of the door seat crane, and can also be specially designed according to the on-site installation requirements.

Основные характеристики

• The YWK-KW pedal frequency converter brake can change the braking torque and braking time in time by changing the depressing amplitude of the pedal controller.

The brakes are sensitive to action, and the brake torque increases and falls rapidly.

The unique torque loader design allows the brakes to be combined with no impact, achieving soft braking.

• The foot controller is designed according to ergonomics.

Long pedal type, operating pressure of 20N-60N, easy to press and feel calm.

Manual control can reduce operating strength during short-term continuous braking, and can adjust the torque by manual torsion.

• The brake handwheel can automatically self-lock braking when power is cut off, shut down or fault, and it will automatically open when starting; it can also be manually controlled

to achieve self-locking and opening; In an emergency, the brake handwheel can also be turned manually to achieve self-locking and opening.

When the self-locking mechanism is braked, the operating braking delay is 1.5 seconds, and the torque growth time is 0.5 seconds; the full opening time is no more than 2 seconds.

Automatic and manual functions can be converted freely.

• Use the inverter controller of a well-known brand to control the new PED inverter to achieve the requirements of high torque, high precision, wide speed regulation and frequent

start-up; The system frequency conversion control module can work normally within 1 second; it can also realize multi-drive synchronization control, good synchronization, stable braking

torque and stable and undegradable.

The control system consists of a frequency converter control module, an operation monitoring module, a DC power management and a DC motor control module and a system safety

operation protection module.

It also comes with an output (MA, MB, MC) interface, which facilitates online control of the system; multiple state instructions are convenient for operation.

• The PEd frequency converter is designed in accordance with DIN15430 standard, adopts a fully sealed single push rod structure, high-pressure cast aluminum alloy shell; non-oil-

immersed frequency converter motor, F-class insulation; IP65 protection level.

The seals and bearings are both internationally renowned brands, with excellent performance and long service life.

• The brake frame is suitable for horizontal installation and can be designed according to on-site installation requirements, making it simple to install.

The main twist points of the brake frame are equipped with self-lubricating bearings, which have high transmission efficiency, flexible and reliable movements, and long service life;

The brake frame has a self-reset mechanism to ensure rapid reset, and the reset speed can be adjusted by the reset spring; the equal withdrawal mechanism can ensure equal withdrawal

distance; the leveling device can eliminate the deviation caused by the brake frame due to its own weight at any time;

The brake tiles are equipped with an automatic follower device, which completely avoids the phenomenon of the brake lining block floating on the brake wheel without adjustment; the plug-in

brake tiles are embedded, which are quickly installed and easy to replace.

• The electric wear automatic compensation device can automatically detect and perform automatic compensation adjustment every time the self-lock braking is turned on.

The electric compensation device realizes electric compensation within the service life of the friction material.

The compensation accuracy is 0.3mm on one side each time, and a friction material wear limit indication is provided.

During automatic function, wear compensation can be completed every time the system is stopped or started.

• The intelligent backup DC power management module can provide stable power for electric self-locking braking and wear automatic compensation devices.

The power management module has the functions of power management, intelligent charging, automatic conversion, and large current discharge.
