High-Speed Control Inverter AC Motor Inverter 7.5KW 3 Phase Frequency Drive
Product Features of variable frequency drive
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 starts 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 occur.
