INVT VFD 75/90 kW 3 Phase

OVERVIEW:

INVT general purpose series high performance universal frequency inverter is the enhanced edition It adopts the DSP control system supplies sensorless vector control and V/f control. The performance is more perfect and stable. It is widely applied in Pump & Fan and some applications with high speed control accuracy, rapid torque response and high performance at low frequency.

Features:

• Three control modes: without PG vector (SVC), V/F control, and torque control;
• Starting torque: without PG vector control: 0.5Hz/150% (SVC);
• 18.5kW-90kW inverter built-in DC reactor to improve input power factor and increaseoverall efficiency and stability;
• Internal brake unit with every specification 0.75-15kW, so that the braking resister can be connected directlyfor a quick stop;
• 16-steps simple PLC, multi-speed control, and PID control
• Supporting multi-frequency installation methods: digital setup, analog quantity setup, PID setup, and communication setup;
• Supports starting and stopping DC brake;
• The input and output terminals may be freely programmed, so users may combine a variety of operating modes as needed;
• Equipped with jump frequency control which prevents mechanical resonance and makes the system more stable and reliable;
• Equipped with instantaneous power failure non-outage capability;
• Equipped with sleep-wake delay installation capability;
• Equipped with over-torque detection;
• Variety of maximum frequency setting source options;
• Equipped with a bidirectional shift key , which enables users to use the shift key to view real-time parameters;
• Rotation speed tracking re-start function: allowing rotating machinery to be started smoothly and without any shocks;
• QUICK/JOG function: users can freely define multi-functional shortcut keys, and by setting up these parameters users can quickly browse different function codes of modified which are different from default values;
• Equipped with automatic voltage adjustment function, which can effectively resolve problems with high-power motors low-frequency vibrations;
• Equipped with vibration suppression;
• Offering a variety of fault protection functions: over-current, over-voltage, under-voltage, over-temperature, phase-failure, overload, etc.
