Chf100a Series Universal Variable Frequency Drive With Sensorless Vector Control

 CHF100A Series Universal Variable Frequency Drive with Sensorless Vector Control

Description

CHF100A series high performance universal inverter(AC Drive) is the enhanced edition of CHF series, which is combined the advantage of CHF100 & CHE100. 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

1.       Three control modes: without PG vector (SVC), V/F control, and torque control;

2.       Starting torque: without PG vector control: 0.5Hz/150% (SVC);

3.       18.5kW-90kW inverter built-in DC reactor to improve input power factor and increaseoverall efficiency and stability;

4.       Internal brake unit with every specification 0.75-15kW, so that the braking resister can be connected directlyfor a quick stop;

5.       16-steps simple PLC, multi-speed control, and PID control;

6.       Supporting multi-frequency installation methods: digital setup, analog quantity setup, PID setup, and communication setup;

7.       Supports starting and stopping DC brake;

8.       The input and output terminals may be freely programmed, so users may combine a variety of operating modes as needed;

9.       Equipped with jump frequency control which prevents mechanical resonance and makes the system more stable and reliable;

10.   Equipped with instantaneous power failure non-outage capability;

11.   Equipped with sleep-wake delay installation capability;

12.   Equipped with over-torque detection;

13.   Variety of maximum frequency setting source options;

14.   Equipped with a bidirectional shift key , which enables users to use the shift key to view real-time parameters;

15.   Rotation speed tracking re-start function: allowing rotating machinery to be started smoothly and without any shocks;

16.   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;

17.   Equipped with automatic voltage adjustment function, which can effectively resolve problems with high-power motors low-frequency vibrations;

18.   Equipped with vibration suppression;

19.   Offering a variety of fault protection functions: over-current, over-voltage, under-voltage, over-temperature, phase-failure, overload, etc.
