●
Provides comprehensive fault protection functions (including
overvoltage protection, undervoltage protection, overcurrent
protection, module protection, heatsink overheating protection, motor
overload protection, external fault protection, etc.), ensuring safety
and reliability.
●
Complete energy regeneration drive: Equipped with a cabinet containing
an energy-regenerative power supply unit, which includes all
components for energy-regenerative operation (including the input-side
filter). The energy-regenerative power supply unit enables energy
conversion between motoring mode and generating mode; the power supply
unit automatically feeds back regenerated energy to the power grid in a
sine wave manner, resulting in low grid-side current harmonics. Since
no braking unit or external braking resistor is required,
installation is simpler; it is more energy-efficient and environmentally
friendly.
● Rich peripheral interfaces to meet various application scenarios.
● Multiple communication methods: Standard MODBUS communication, optional PROFIBUS, supporting multi-machine communication and enabling coordinated control of multiple machines.
● New PWM dead-time compensation technology, which effectively reduces motor noise and motor losses.
● Excellent open-loop and closed-loop vector control performance, significantly improving the dynamics and stability of the system; excellent torque control performance, achieving precise torque control.
A four-quadrant Vector Inverter
is a new type of rectifier that converts alternating current (AC) to
direct current (DC). It is typically connected to an inverter and an
asynchronous motor, used in AC-DC-AC drive electric locomotives, and is
particularly suitable for speed control systems requiring frequent
traction and regenerative braking; high-frequency energy feedback
regenerative braking; and environments with high requirements for grid
power quality, such as speed control systems requiring frequent traction
and regenerative braking.
