VEICHI provides OEM/ODM Service for TOP Customers. AC70T hoisting special frequency converter is specially designed for hoisting industry applications. Complete functions, good protection effect (resistance to salt spray corrosion), and excellent performance to ensure the safety and reliability of lifting machinery. Product Advantages 1. Master-slave speed synchronization control function: When the double hoisting mechanism lifts a heavy object at the same time, then it can ensure that two hoisting mechanisms are synchronously promoted to ensure safety 2. Real-time correction control (closed-loop mode): It is suitable for applications with large spans. The master-slave adopts real-time position correction to meet the synchronous control of the position of the cart (applicable to driving and traveling equipment of gantry crane) 3. The slack rope detection function: to prevent the unsafe operation of the light load and high-speed function due to the malfunction of the crane rope under slack conditions 4. Support Profibus-DP, Modbus, and CANopen communication protocol to achieve the communication connection between multiple frequency inverters and PLC and HMI. Applications Port machinery, ship machinery, construction machinery, mining machinery, cranes, gantry cranes, electric hoists, cranes and hoists, etc. The output voltage: Output under rated conditions: 3-phase, 0 input voltage, error less than 5% Output frequency range: 0 320Hz
