Close Loop Inverter
Close Loop Inverter
Model CHV100 Series is a vector control frequency close loop inverter. Features: power range – 4~630 kW; adopts advanced modular design concept; dual-CPU control platform – DSP is responsible for current vector arithmetic while 32 bit MCU is in charge of control function; static and dynamic motor parameter autotune; ensures excellent vector control; achieves high accuracy close-loop speed control and torque control using PG card to receive pulse signal from encoder, torque control – offers multi-mode torque setting; constant tension control – the built-in roll diameter calculation can implement direct (indirect) tension control in wind and unwind application; external LCD panel can monitor three parameters at the same time; parameter copy function make several drives commissioning more convenient; CHV110 series energy saving cabinet (7.5~75 kW) has built-in bypass system, which ensures continuous production; and specially designed for water supply application, which is able to control up-to 7 pumps with circular switching and dormant control function.
