ME700 

Module combination inverter

Functional features


Customers can choose separate power modules and assemble on their own or choose whole-set
cabinet products according to their own requirements. The compact modular design and rich port
resources provide users with a powerful programmable function, which can meet a variety of
application demands เท various industrial sites. STEP ME700 series of cabinet frequency inverters
can provide the silicon controlled rectifier and AEF active rectifier modes, and users can choose
different way of rectifier according to specific needs. This series has many features:
Can reduce the current harmonics
Stable DC bus
Reduce reactive power
Current-sharing control
Speed tracking start - smooth and shock-free
Internal contracting brake logic - smooth, safe, and reliable
Torque given function
Weak magnetic constant power function
Memory torque function
Motor parameter and operation curve switching function
Speed/torque switching supports dynamic switching

Characteristic

The compact modular design and rich port resources provide users with a powerful programmable function, which can meet a variety of application demands in various industrial sites. STEP ME700 series of cabinet frequency inverters can provide the silicon controlled rectifier and AFE active rectifier modes, and users can choose different way of rectifier according to specific 

Application characteristics


1. The rectifier feedback unit can feed back energy to power grid, with the power factor close to 1.0 and the current            harmonic less than 4%;
2. The whole quay crane main drive system shares DC bus, and electric power and power generation are recycled   

    between multiple drives internally;
3. The lifting drive is equipped with constant power function and brake management function;
4. The lifting carts share an inverter, and the pitching cars share an inverter, with two sets of parameters built in the

     inverter
5. Lifting 1 inverter and lifting 2 inverter are master-slave control, lifting 1 is for speed control, and lifting 2 is for torque

     control, with torque given from the torque output by lifting 1 inverter speed loop;
6. Most of the large vehicle is in multi-motor parallel connection, with one inverter control, เท VF control mode with 

     speed feedback
7. Most of the large vehicle is in multi-motor parallel connection, with one inverter control, in VF control mode with 

     speed ME700 feedback

8. The lifting and pitch are for closed-loop vector control mode
