INVT GD35 closed-loop vector frequency converter: empowering the machine tool industry with efficient and precise control
1. Strong low-speed torque output capability
The GD35 series frequency converter can output 200% of its rated torque at 0Hz in closed-loop vector mode, making it easy to cope with large load impacts during machine tool spindle startup and low-speed cutting. Its overload capacity of 150% rated current for 1 minute and 180% rated current for 10 seconds can ensure stable operation of the equipment under heavy load conditions.
2. Accurate spindle positioning and indexing function
In response to the positioning requirements of machine tool spindles, GD35 is equipped with a high-precision spindle stop algorithm that supports both encoder Z-phase positioning and external photoelectric switch positioning, ensuring accurate positioning without overshoot. Simultaneously providing 7 programmable indexing angles and 4 zero positions, which can be quickly switched through terminals to meet the indexing requirements of different processing techniques.
3. Rich fieldbus communication support
INVT GD35 is fully compatible with mainstream industrial fieldbus protocols, and in addition to standard Modbus communication, it also offers expansion options for PROFIBUS-DP, CANopen, and Ethernet communication. The centralized control and parameter monitoring of multiple frequency converters can be achieved through the upper computer, greatly improving the automation level of the production line.
4. Improved protection and maintenance mechanisms
This series of frequency converters has complete self diagnosis and protection functions, which can monitor key parameters such as input and output voltage, current, module temperature, etc. in real time. When abnormalities occur, protection will be triggered immediately and fault codes will be displayed. Simultaneously supporting parameter copying function, batch configuration of parameters for multiple devices can be quickly achieved through the keyboard, reducing debugging time.
