CHV190-220G-4 Variable Frequency Drive CHV190 220.0kW 3-ф/380

CHV190-220G-4 — three-phase frequency inverter from INVT CHV190 series, rated at 220.0 kW active power capacity (nominal output current 415 A) for electrical grids with 3-phase 380V supply voltage. The VFD supports sensorless vector control (SVC) and scalar V/F control, delivering smooth motor speed adjustments and dynamic torque response. The device features IP protection standard, integrated EMC filter, and built-in Modbus RTU RS-485 communication interface.

Typical Applications:

• Industrial conveyors, mixers, extruders, and packaging machine drive systems.
• HVAC fans and automated pump systems utilizing built-in PID controller for constant pressure hold.

Please Note: Perform motor autotuning (rotating or static) before first system startup. When installing motor cables longer than 50 meters, an output reactor (du/dt filter) is highly recommended to protect motor winding isolation from voltage spikes.

INVT CHV100 — Positioning

INVT CHV100 is a flagship series of high-performance variable frequency drives designed to deliver unprecedented dynamic response and precision in speed and torque control. By implementing advanced closed-loop vector control algorithms via optional PG feedback cards, this inverter achieves speed control accuracy up to ±0.02% and is capable of maintaining rated torque even at zero speed. The dual-CPU platform, comprising a high-speed DSP for current vector arithmetic and a 32-bit ARM processor for control functions, guarantees instant reaction to load variations. This makes the series an outstanding choice for demanding industrial applications requiring precise tension control and superior dynamic stability.

Typical Applications:

• Industrial Extruders & Heavy Mixers: Provides stable output torque at ultra-low frequencies, smoothing out startup overloads and compensating for raw material viscosity changes without line interruptions or motor voltage drops.
• Paper & Textile Machinery: Co-ordinates the speed of adjacent linear sections through a closed-loop encoder feedback system, preventing paper web tearing or fabric sagging.
• High-Precision Machine Tools & Spindles: Precise speed control under heavy cutting loads, smooth workpiece startup, and rapid deceleration using built-in or external dynamic braking resistors.

Competitor Comparison

Compared to Delta C2000 and Yaskawa A1000, the CHV100 model demonstrates superior overload resilience during extended operations and serves as a highly cost-effective B2B solution for machine park modernization, although Yaskawa offers a slightly higher instantaneous peak overload capacity.

Series Limitations:

• For heavy-duty mine hoists or passenger elevator applications requiring integrated mechanical brake control sequences and specific movement comfort profiles, we highly recommend choosing the specialized INVT CHV190 or INVT CHV180 series.

Our Practical Experience:

When commissioning the CHV100 drives, we found that dynamic motor auto-tuning is a mandatory step for stable closed-loop operation. It accurately identifies rotor leakage inductance and stator resistance parameters. Configuring Modbus registers for switching between speed and torque control modes operates seamlessly via writing values into control register 0x2000 without requiring a complete motor stop.
