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 theinverter 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.

 

 

1,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.

 

 

2,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.

 

 

3,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.
