Tangshan frequency converter, vector type PLC frequency converter has basic functions such as voltage regulation, frequency modulation, voltage stabilization, speed regulation, etc. It applies modern science and technology, is expensive but has good performance, complex internal structure but simple to use, so it is not only used for starting electric motors, but widely used in various fields, with various powers, shapes, volumes, and purposes.
Tangshan frequency converter - vector type PLC frequency converterFeatures:
1. Power range: 1.5~400KW.
2. Compact and reasonable structural design, with a specially designed enclosed space for the electrical part, which has waterproof and dustproof functions, ensuring the safety and reliability of the circuit part.
3. Dual LED panel display allows for simultaneous monitoring and debugging with customers; The keyboard parameter copying function facilitates customers to copy multiple frequency converter programs. 4. PID closed-loop control can be used for constant temperature and constant pressure process control systems.
5. Built in simple PLC function, which can achieve various operational functions through control terminals.
6. Sag control function: Automatically balance the power of each variable frequency drive system on the same transmission chain, and a single variable frequency drive can achieve torque motor characteristics.
7. Adaptive control technology, automatic current and voltage limiting, and under voltage suppression during operation.
8. It has excellent frequency tracking function, which can capture the motor operating frequency and accelerate to the set value at the moment of power loss and power on of the frequency converter. It is suitable for large inertia loads such as fans and pumps.
9. Standard configuration of RS485 communication interface, optional MODBUS protocol and four party custom protocol; Equipped with linkage synchronization control function, it easily realizes the interconnection and intercommunication between the frequency converter and other industrial control equipment such as PLC and industrial computer.
10. Load self balancing capability: When using RS485 communication linkage control function, the host synchronously sends frequency and torque load commands to each slave to achieve torque balance of the variable frequency drive system.
11. Widely applicable, incorporating macro switching and macro calling concepts, with built-in functional modules such as wire drawing machines and textile machinery
Precautions for vector type PLC frequency converter:
1. It is strictly prohibited to short-circuit or ground the output terminals of the frequency converter, otherwise it will cause damage to the internal components of the frequency converter.
2. Avoid short circuiting between the output line and the inverter casing, otherwise there is a risk of electric shock.
3. It is strictly prohibited to connect capacitors or LC/RC noise filters with phase advance at the output end of the frequency converter, otherwise it will cause damage to the internal components of the frequency converter.
4. When installing a contactor between the frequency converter and the motor, the output terminal contactor switch action cannot be performed during the operation of the frequency converter, otherwise a large current will flow into the frequency converter, causing the frequency converter protection action.
5. The cable length between the frequency converter and the motor: When the cable between the frequency converter and the motor is long, the high-order harmonic leakage current at the output end will have adverse effects on the frequency converter and peripheral equipment. It is recommended to install an output AC reactor when the motor cable exceeds 100 meters
