AB 1336 PLUS II Engineering Drives

Product Overview: The 1336 PLUS II is an AC drive with novel control methods, flexible applications and excellent performance. It adopts IGBT power modules and advanced control algorithms to meet a wide range of motor control requirements, and complies with a number of international standards.

Structure and Installation: There are various structural forms, such as standard chassis type, combination type, etc.; installation dimensions vary according to the structure and power, and there are detailed requirements for the installation environment, power supply, wiring, etc., and there are specific specifications for the power supply wiring and control wiring of the inverters in different power segments.

Function description: with motor sensorless vector control, process PI control, encoder feedback and other functions, but also has the power supply voltage drop across, a variety of braking modes, fault diagnosis and storage and other features, parameters are rich and programmable.

performances

The 1336PLUS II engineering inverter offers very simple parameterisation and operation, rare flexibility and outstanding control functions, whether for simple speed control or powerful vector control.

The 1336PLUS II engineering inverter uses the latest IGBT (Insulated Bipolar Tubes) power modules and advanced control algorithms to provide smooth performance at any speed, exceptional torque, and low-noise, high-efficiency motor operation.

Scenario Applications

Continuous casting production field: In Xuansteel No.4 and No.5 continuous casting machines, more than 90 sets of 1336 PLUS II frequency converters are used to drive mechanical equipment from ladle rotary table to transverse steel shifting car, with power ranging from 0.75KW to 45KW. through ControlNet network and Remote I/O network, the real-time control of the transmission equipment through a remote network is realised. 

For example, the speed sensorless vector control mode and s-curve acceleration function are used to meet the needs of rotating equipment for automatic change of high and low speeds and in-place stopping, and to reduce the impact on the gearbox; in the control of the steel transfer car, the PLC works with the frequency converter to adjust the speed according to the operation and limit switches, and the braking function uses the DC brake function with the holding brake to protect the equipment and avoid malfunctions. 

At the same time, in the application of booster pump, using its automatic energy-saving function, no-load or light-load output voltage reduction, reduce power consumption. The use of this device improves the real-time, accuracy and reliability of the system, reduces the installation, commissioning and maintenance costs, and ensures that the continuous casting machine is put into operation and reaches production on time .

Thermal Power Station: The heat exchanger evacuation pumps in the Zhenhai Thermal Power Station are controlled by 1336 PLUS II AC frequency converters with power ratings of 75kW, 55kW and 37kW respectively, which are used to control three evacuation pumps per generating unit. The inverters utilise sensorless vector control to provide smooth control performance and high torque to the motors, enabling direct control of the pump motor speeds according to load requirements. As a result of the application, the running current of the 75kW pumps has been reduced from 145 amps to 98 amps, resulting in energy savings of nearly 30 per cent and a payback of the investment in just sixteen months. At the same time, air pockets and pump wear were reduced, improving the operating efficiency of the sparging pumps, enhancing system stability and reducing power generation costs.

Critical drive control for steel continuous casting process: The 4, 5 and 6 continuous casting machines in Xuansteel's steelmaking plant use the 1336 plusII frequency converter for drive control of billeting, straightening and vibration. The frequency converter provides a variety of communication methods, including device net, control net, ether net and DH+/RIO communication methods, which better meets the process requirements of continuous casting production, and its drive level directly improves the output and quality of continuous casting billets, which is more suitable for the requirements of modern continuous casting with high efficiency.
