Q-7000 series of brilliant inverters for operation of elevators and escalators are designed to have a lot of exclusive features including Q-7000-EC especially for escalator, Q-7000-EL and Q-7000-IP especially for elevator.

Q-7000 series are all the type adopting IGBT’s PWM control and current vector control, V/F control. Q-7000 series have the function such as connection-point-memory & DC0-10V EASY TUNING, loading compensation for start-up torque, and manual vernier adjustment correcting. High efficiency and safe function, 300% torque compensation. Monitor torque compensation output of the inverter at anytime so as to reduce the shocking the elevator during running. The series of products has easy tuning function to the motor parameters and are complied with the regulation of GB, with braking unit (for≤45kw) and speed feedback unit.

Q-7000-EC is for open loop control without built in PG card, especially used for escalator with brilliant performance by long life design and support RS-485 communication port.

Q-7000-EL is used for geared asynchronous motor. PG card is built in for customer to realize the high fine speed control. Q-7000EL support standalone signal, frequency division, isolated signal, and open collector output functions for Encoder. 200% of rated current for 10 seconds. Speed control accuracy is nominal 1:100 and could reach 1:1000 with PG.

Q-7000 IP is used for gearless synchronous motor. It also support standalone single, frequency division, isolated signal and open collector output functions for Encoder. Q-7000IP supports Line drive 8192 C/T. Its ultra-slim design is adequate for machine room-less elevator. It combines 32- digit vernier-adjustment current vector control and stochastic PWM control. The ultra-low noise, with adjustable wave frequency, carrier frequency 2k-15k is adjustable.

All of Q-7000 series support the RS-485 communication port and other more functions that customers would find most necessary in elevator controls to provide an inverter that delivers performance which fits the elevator systems.
