Product Features
Specialization characteristics
Anti-sway control
· Control the swing angle of the spreader by controlling its running speed, thereby suppressing the swing of the spreader and achieving smooth control and efficient operation.
Load and speed
· Adjust the equipment operating speed in real time according to the current load changes, taking into account efficiency and safety, so that the equipment can work in the best working condition
Slide hook protection
· The sliding hook is detected during the braking process, and the sliding hook is protected by controlling the motor output to hover to prevent accidents.
Deceleration limit
· Simple positioning is achieved through the cooperation of deceleration limit and stop limit, so that the control object stops in the preset safe area
Anti-loose rope protection
· When going up, it runs at a fixed speed and detects whether the heavy object is mentioned. It detects whether the heavy object is mentioned and then accelerates slowly to rise steadily.
Operating lever zero return detection
· When powering on, the status information of the operating lever can be judged to choose whether to accept the running command to avoid the danger caused by the initial instantaneous operation after powering on.
Macro parameters
· The corresponding lifting mechanism can be selected according to the lifting parameter macro setting value, such as 0: lifting mechanism, 1: translation mechanism
Brake control
· When the inverter starts and stops, the brake is controlled by detecting frequency and current to avoid rolling, thereby improving system performance, safety and stability.
Multiple motor switching
· Internally supports 4 sets of motor parameters, and can drive 4 different motors through command switching

High reliability
Innovative independent air duct design
· The whole machine has an independent air duct design, and sensitive components are isolated from the air duct, which greatly improves the product's adaptability to the environment.
· Effectively prevent dust and impurities from entering the inside of the inverter and avoid failures caused by electrical short circuits, component damage, etc.
Thermal design concepts and professional thermal simulation analysis
· Adopt efficient and accurate thermal simulation platform software to ensure the thermal reliability of the entire machine
· Advanced thermal testing and verification technologies and devices effectively test the theoretical results of thermal design
Rigorous whole machine temperature rise test
· Rigorous full load and overload verification test procedures, as well as strict temperature rise acceptance standards for key components, to meet long-term reliable operation under extreme load conditions
· All products undergo high-temperature load aging before leaving the factory, effectively preventing scattered failures of interception devices and ensuring product quality before leaving the factory.
Automatic spraying process of conformal anti-paint
· Using the automatic spraying process of conformal anti-paint, different spraying strategies can be designed according to different circuit boards, effectively ensuring the uniformity of circuit board spraying and the consistency of product batches

High adaptability
Wide voltage range design
· Rated voltage: three-phase 380V～480V
· Input power frequency: (50Hz/60Hz) ±5%
· Allowable voltage fluctuation range: -15%Vac～+10%Vac
Little external interference
· Built-in C3 filter can effectively suppress high-frequency harmonics generated by the inverter during operation, meeting the requirements of the European Union EN61800-3 standard
· Simple and friendly EMC ground-breaking design can effectively reduce ground leakage current
structural design
· Book-type design, reducing the volume by about 40% compared to traditional models
· Can realize side-by-side installation of the whole machine

Excellent performance
Comprehensive motor drive technology

Accurate motor self-learning function
· Can accurately perform motor parameter self-learning, facilitate operation and debugging, and improve control accuracy and response speed.
· Comprehensive and rich self-learning functions, including a variety of motor self-learning functions (dynamic, static, static + dynamic)
Dynamic self-learning: load self-learning must be disconnected, suitable for occasions with high control accuracy requirements.
Static self-learning: It is suitable for situations where the motor cannot be separated from the load to avoid dynamic self-learning after the equipment is installed.
Comprehensive motor control modes
· V/F control mode
· Open loop vector (OLVC) control mode
· Closed loop vector (CLVC) control mode
Large starting torque
· Open loop vector (OLVC): 0.5Hz/150%
