7.5KW Output 3 Phase 380V AC Variable Frequency Drive VFD Low Frequency Inverter
Product Features:
1. With TI's latest high-speed DSP chip and independent
intellectual property control software, the motor can run stably in
various application environments by giving full play to the
characteristics of software and hardware.
2. New wave by wave current limiting control algorithm, stable
current, and voltage control, ensure the inverter run without fault
under limit conditions
3. New current, voltage, control algorithm, plus a unique
excitation current control, to ensure that the motor fault free
fast start and stop.
4. New motor model, low-frequency motor running speed stability,
high torque, current control accuracy, no-fault shutdown,
high-frequency motor running speed stability, low current.
5. New software speed tracking algorithm, tracking current, voltage
impact is small, tracking speed is accurate.
6. The carrier frequency can be automatically adjusted with the
frequency conversion temperature and operation frequency to ensure
reliable operation under the condition of a small frequency
conversion temperature rise.
7. The maximum frequency of a standard machine is 3000hz, one
machine is multi-purpose, which can meet the multi-purpose
processing needs. It can realize a variety of frequency switching.
8. Super overload capacity, 150% 60s, 180% 10s, 200% 0.5s
9. Default one set of motor parameters, can customize multiple sets
of motor parameters, can drive different types of motor.
10. Four times of fault parameter record, detailed record of the
detailed state of the inverter when the fault occurs, and record
the maximum current, maximum voltage, and maximum temperature
during the operation of the inverter, so as to facilitate the
analysis and treatment after the fault occurs.
