Delta's VFD-C200 series inverters adopt the design concept of ultra-miniature structure: small size, compact structure, reliable performance, and optimal heat dissipation design, which is convenient for users to install and debug. Taking into account the possibilities of industrial production environments, the drives are manufactured from special materials and comply with the IEC/EN 60068-2-27 standard to operate in relatively harsh industrial production environments.
As an important equipment of industrial drive control system, the driving force of the inverter is still a key consideration for users when selecting models. This VFD-C200 series inverter can provide high-order vector control modes FOC PG, FOC sensorless, and Pmsensorless. The low-horsepower drive can control the IM/PM motor, and it has the functions of resonance frequency suppression and resonance frequency jumping, reflecting a powerful driving force. Wide power range (0.4kW - 7.5kW), and built-in standard PLC program editing function with a capacity of up to 5000 steps, users can realize personalized functions.
With such a powerful driving function, it is of course not inferior in terms of communication with the outside world. Delta's VFD-C200 series inverters adopt industrial control network communication standards, built-in high-speed communication MODBUS RS 485 and CAN open cards, and can be equipped with a variety of communication modules to support the construction of fieldbuses. This is convenient for users to a great extent.
In addition, Delta's VFD-C200 series inverters adopt a modular design, which reserves sufficient options for later expansion applications. For example, the product can be programmed to select and control the ultra-long acceleration and deceleration unit, and has independent and multi-stage acceleration and deceleration control; It is equipped with multi-function input and output digital terminals, and includes high-speed counting and encoder input terminals; Multi-channel analogue interface; Closed-loop interface control design; DC bus parallel connection design; The standard configuration can be plugged in with high-brightness LED operation interface, etc., which greatly enhances the flexibility of user applications.
In the face of the development trend of a single product gradually shifting to a complete solution, Delta's VFD-C200 series inverters still have advantages. In response to the special process needs of different industries, Delta's VFD-C200 series inverters can provide users with safe, reliable, and cost-effective integrated solutions to meet the diverse and personalized needs of users.

Debugging Delta's inverter method
1. Acceleration and deceleration time
The acceleration and deceleration time is usually confirmed by the rise and fall of the frequency setting signal. In the commissioning of Delta inverters, it is often used to set a long acceleration and deceleration time according to the load and experience value, and the frequency rise rate of the motor must be constrained when it accelerates to avoid overcurrent. When slowing down, ...
