Features:

Low frequency and high torque: PG vector control: 0Hz/200% (rated torque); Space voltage vector: 0.5Hz/150% (rated torque)

Good load adaptability: The control algorithm is optimized for lifting applications, and the output torque can be adapted according to the load situation, and the no-load and load-bearing can obtain good comfort.

Tower crane rotation and eddy current control: The control of tower crane rotation can realize eddy current, and support rapid stopping, fast switching of forward and reverse rotation, and low-speed jog positioning.

Conical rotor motor control: Adjust the magnetic flux according to the characteristics of the conical rotor motor, realize fast brake release and brake holding control, simplify the debugging steps, and ensure the safety of the equipment.

Dedicated brake logic: brake logic control fusion torque verification, brake release control after the torque is established, safety does not slip; The logic control of the brake supports the selection function of starting direction and forward and reverse switching, which meets various starting requirements and has good adaptability.

Stroke limit protection: Integrate the functions of upper/lower limit and up/down deceleration limit to restrict the operation of the crane within the specified range, ensure safety while optimizing the shutdown mode and improving equipment efficiency.

Anti-sway function: Sensorless anti-sway control algorithm is used to realize the anti-sway control of various lifting equipment, which is simple to debug and has good adaptability

The standard anti-sway function can effectively suppress the shaking of goods during translation and improve work efficiency

The high-efficiency anti-roll function can effectively reduce the shaking of the goods during translation and improve work efficiency

Rope loosening protection: avoid safety accidents caused by high-speed lifting, malfunction of the speed lifting function and rope failure in the state of rope relaxation.

Smooth lifting: When running at high speed, when the hook lifts the load, the speed is automatically reduced, the hook is lifted smoothly, and the impact of the sudden load on the crane is reduced.

Zero servo: The motor is locked at zero speed, and the motor can remain locked at zero speed even if an external force in the forward/reverse direction is applied. When the brake fails, it can also drive the motor to control full-load hovering or controlled low-speed lowering to ensure safe use.

Light load speed increase: support constant power, stepped speed limit mode, according to the load situation to achieve the best running speed matching, shorten the crane operation cycle, improve the operation efficiency.

Warehouse protection: During the lifting process, after an abnormality such as hanging on other objects, the machine will be shut down in an emergency manner to ensure safety and improve efficiency

Safe torque shutdown (STO/SIL2): cut off the torque output when the motor stops to prevent the equipment from starting unexpectedly, which is reliable and safer; The inverter is uninterrupted, and can continue to monitor the system status and recover quickly.

Load height measurement: integrated roll diameter calculation function, which can output hook height information to the outside to guide the driver to reduce the running speed and prevent the collision between the hook and the roll simplification.

Master-slave control: support two control modes: power balance mode to ensure uniform motor output and meet the application requirements of multi-motor rigid connection drive and one load; Speed synchronization mode to ensure the synchronous lifting of the lifting mechanism to ensure safety; It supports one master and multiple slaves, and master-slave switching, making the application flexible.

Tower crane rotation control: the inverter has a built-in special algorithm to achieve stable start and stop, support anti-vehicle and low-speed gear hook, higher efficiency and easier operation

Lifting special application macro: solidify multiple application macros, users can set parameters with one click, and the corresponding application macro parameters can be viewed in the manual, and custom application macros are supported.

3 groups of motor switching: At the same time as the motor switching, we can also realize the switching of application macros, so that we do not need to set some functional parameters after the application macro switching is completed at the same time as the motor switching, and even when the master-slave mode is switched, we can also realize the switching of application macros.

Positioning and parking: In the closed-loop mode, it supports positioning and parking control of large vehicles, small cars, and lifting, and the equipment operation is more accurate and efficient

Open-loop/closed-loop one-key switching: When the encoder fails, it can quickly switch to the open-loop control mode through one-key setting, and switch the application macro at the same time to ensure the normal operation of the device (it does not respond during operation).

Multiple operation modes: Support joystick, grading joystick, electric potentiometer, communication, remote control, grading remote control and other speed given methods to meet the application requirements of various lifting equipment.

Abundant expansion cards: support 3 expansion cards (IO expansion card, communication card, PG card), which can cope with different scheme applications (2 cards can be expanded below 5.5KW).

	Anti-sway and anti-sway of large and small cars	When the anti-sway function, the encoder needs to be installed for lifting, and the lifting and the large and small car frequency conversion are connected through analog AI or HDI, or are equipped with CAN master-slave card communication, so that the large and small car frequency conversion obtains the height value of real-time lifting and frequency conversion, and then combined with the built-in amplitude anti-sway algorithm, the output of the given frequency and acceleration and deceleration time, the large and small car frequency conversion accelerates or decelerates according to the start-stop command and the given frequency, which can eliminate the swing when the frequency conversion reaches steady state or stops.
