Utilizing vector control to output higher low-speed torque
·By adopting our company's unique vector control technology, we can generate high torque (1Hz → 150%) even at medium and low speeds. In devices with large load fluctuations and requiring sufficient starting torque, such as conveyor belts carrying a large number of semi-finished products and heavy-duty turntables, they can also operate smoothly. It can also exert its power in the operation of can sealing machines, stamping machines, injection molding machines, etc. that also require low-speed torque, without the need to use frequency converters that amplify the capacity by one or more levels, contributing to cost reduction and installation space reduction.
·In addition, it is equipped with automatic tuning function, which allows for simple and appropriate parameter settings to achieve good motor characteristics.
Adopting a large operation panel further improves operability
·Large and clear 7-segment display
·A large potentiometer that is easy to operate
·Simple and easily recognizable key configuration
The operation panel is detachable
·Simply install on other devices to copy parameters for use.
·The DIN size of 72mm × 72mm can maintain its appearance even when installed on the cabinet.
·Users only need to prepare commercially available LAN cables (straight type) to connect the operation panel and the host, which has the characteristics of simple procurement and affordable price. (up to 5m in length)
Standard equipped with serial interface RS485
Up to 31 VF200s can be controlled through RS485 serial communication. The communication protocol corresponds to Modbus RTU and MEWTOCOL, which can easily send speed indications or collect data through a computer or PLC.
Our FP series PLC has Modbus RTU and MEWTOCOL master station functions.
Corresponding textile winding machine functions
● Textile winding reciprocating operation function
·The winding mode control function operates at the frequency of the triangular wave mode shown in the figure below.
● New operating mode
·Random swing mode: can effectively prevent winding from accumulating at the same point
·Wire winding length stop mode: automatic stop function after accumulating a certain length of wire winding
·Pulse input length calculation mode: convenient for displaying and calculating winding length, and the calculation results can be communicated
·Two point mode: The reference frequency smoothly changes with the winding length and eventually changes to the second frequency
Built in output short-circuit protection circuit
Even if the motor malfunctions due to overload or other reasons, causing a short circuit, VF200 will detect overcurrent and protect the circuit by instantly disconnecting the output, so it can be used with confidence.
Equipped with high-speed current limiting function
Even if excessive current flows in an instant due to load changes, VF200 will not trip but continue to operate, thereby improving productivity. Effective for rapid acceleration of heavy-duty turntables and mixing of sticky objects such as bread and noodles.
High construction and maintenance efficiency
