PID Control Function Industrial Inverter VF Control , Invt Inverter Chf100A

Brief Introduction

CHF100A series high performance universal inverter 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

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.
