V&T VY-JY Inverter

V&T VY−JY inverters are high-performance inverters designed to meet motor control needs in various industrial applications, especially manufacturing, textile, and food processing.

Outstanding features of V&T VY−JY inverter

The V&T VY-JY inverter series is a powerful solution for industrial motor control, with many modern features that help optimize system performance.

Wide power range from 11kW to 132kW, suitable for various machines and drive systems.

V&T VY-JY inverter supports many modern control modes, meeting many operating requirements: V/F control, Vector Control 1 & 2, sensorless vector, torque control, and vector control with the sensor.

Outstanding control performance, demonstrated by:

• High starting torque of 180% at both 0.50Hz and 0.25Hz.
• Wide speed control range, with Vector control one being 1:100 and Vector control two being 1:200, allowing flexible application in various operating conditions.
• High-speed stability accuracy, ±0.5% with vector control one and ±0.2% with vector control 2 ensures stability and precision during operation.
• Torque control is also very precise, with an error of less than ±5%.
• In particular, this inverter has a fast response time of less than 20ms, helping the system operate efficiently and flexibly.

In addition, the VY-Jy inverter is also equipped with many features to support operation: Automatic low voltage adjustment, torque and current limit, automatic speed detection for smooth start-up, acceleration/deceleration adjustment according to S-curve, slip compensation and PID control, quick saving and copying of setting parameters.

Flexible installation and communication capabilities with:

• Multiple frequency setting methods:
  • Directly from the dashboard
  • Analog input (AI1, AI2, AI3)
  • Control pulse from DI port
  • Through communication with the host computer
• Wide frequency range support:
  • 0.00 – 300.00Hz (expandable to 3000Hz)
• 2 RS485 ports support Modbus RTU and can be controlled remotely with a distance of up to 500m.
• Support for communication expansion with various expansion cards:
  • PG Feedback Card
  • Power Monitoring Card
  • Phase Sequence Detection Card
  • Communication Interface Card

V&T VY-JY inverter is also equipped with effective braking and braking features, ensuring safety and optimal control during operation.

• Regarding dynamic braking, the inverter supports connection with an external brake to enhance braking efficiency, making the motor stop process faster and safer.
• For DC braking, users can flexibly set the braking current in the range of 0-120% (for constant torque load) and customize the braking time from 0-30 seconds, allowing the motor to stop quickly and accurately when needed.

Thanks to these features, the V&T VY-JY inverter improves operating efficiency and ensures safety for the system and users.

V&T VY-JY also provides comprehensive protection for the motor and system with overvoltage, overcurrent, overload, input/output phase loss, ground short, phase short, overtemperature warning, protection against unstable power supply voltage, and automatic error detection during start-up.

V&T VY-JY inverter not only stands out with its superior control performance and braking features but also brings outstanding energy-saving capabilities:

• ≥93% for power below 7.5kW
• ≥95% for power below 45kW
• ≥98% for power above 55kW
