CHV180 series Lift Inverter 0.5% maximum speed SVC Energy saving running
Brief Introduction
Intelligent control CHV180 series Elevator Inverter is a professional driver for elevator just designed for elevator industry, It not only can control the tractor which driven by gear, but also can control the tractor which driven without gear. It preeminent function and performance can easily matches with elevator control, so it ensures the safety and comfortable level of elevator.
Features
Synchronous motors identify the initial magnetic pole angle in static state; Compatiable with synchronous and asynchronous motor; Apply to asynchronous induction motor and permanent magnet synchronous motor which running speed is less than 4m/s. Start torque compensation without weight sensor; Optimized speed curve; Optimized S curve control, the parameters can be set separately in the process of starting and stopping. It decrease the libration, increase the comfortable level when acceleration, deceleration and stopping. Reliable brake sticking and contactor control function; Optimized speed adjusting loop; Speed adjusting loop adapt variable proportion gain and integral gain control. It improved the dynamic response for starting and stopping, it also improved the comfortable level while constant running. With high performance current vector control and integrated many encoder interface; High order harmonic suppression of power; Force speed down precessing function; Prevent the elevator from top-hitting or bottom-clashing in the process of up or down running.Specifications
