As its name indicates, AS330 escalator integrated drive and controller is a combination of an escalator drive and an escalator controller. It comes with anti-interference capability and design exceeding the highest industrial design standard, and features compact structure, small size, few wire connection, and high reliability. It is also easy for operation and economical.
With functions of both escalator controller and escalator drive, the escalator integrated drive and controller provides escalators very high safety standard, and meanwhile, it can also offers multiple escalator operation control functions to suit customers' demands. Additionally, it allows the escalator to operate in different speeds according to passenger flow, thus helping saving energy.
The escalator integrated drive and controller is composed of a motor drive circuit, power supply circuit, and control circuit. The control circuit of the escalator integrated drive and controller functions to receive the signal and then sends the signal to motor drive circuit. The motor drive circuit also receives power supply signals from both industrial power supply and escalator drive's output power supply, and sends signals to control the escalator traction machine.
With the escalator integrated drive and controller, the escalator working process is divided into two parts. When the escalator is in speed changing or standby status, it is powered by the escalator drive output power supply, and when it is in smooth operation status, it is powered by industrial power supply. The escalator integrated drive and controller ensure escalators have compact structure, convenience installation, simple testing and commissioning, highly effective operation and high safety, etc.
Technical Characteristics and Functions of the Escalator Integrated Drive and Controller
1. The escalator integrated drive and controller is designed with dual 32-bit embedded microprocessors to control escalator operation and electric motor drive.
2. Through making improvement on the equipment hardware, our escalator integrated drive and controller comes with a maximum junction temperature of 175℃, low switch loss and extended service life.
3. The escalator integrated drive and controller provides escalators with variable frequency control and industrial frequency control. To illustrate, it offers fully variable frequency control, bypass variable frequency control, Y-△ control modes to suit customers' varied demands and reduce escalator failure rate. When the escalator is in standby and speed-changing status, it is variable frequency controlled; while in steady operation status, it is industrial frequency controlled. Thus, energy consumption can be reduced.
4. Designed based on new PWM dead time compensation technology, the escalator integrated drive and controller is able to ensure reduced motor noise and loss. Meanwhile, the adoption of dynamic PWM carrier modulation technology also helps reduce motor operation noise.
1. Closed loop vector control for higher performance.
2. New PWM dead-zone compensation technology leads to less energy loss.
