EVO6800 on 400 Mesh Pulverizer

2018-12-04

The 400 mesh super pulverizer can grind the raw materials of traditional Chinese medicine into fine powder. It uses EVO6800 VFD to control the speed of the main machine, sorting and feeding. 

 

 

Technical Requirements

All motors on the equipment are controlled by one PLC. There are manual operation and automatic operation modes from the HMI, showing current, housing temperature, fault alarm and fault prompt.

When the operating currents of the main circuit and the sorting exceed the rated current by 10%, the feeding automatically stops.

When the running current drops to 80% of the rated current, the feeding starts automatically at the same running speed as before it stopped.

 

 

Solution

 

The EVO6800 VFD is activated through the terminal. Its speed is adjusted manually on the HMI screen via the Modbus network. PLC provides frequency through RS485. 

 

 

 

Technical Advantages and Customer Benefits

The IGBT module has a large margin and is able to support high current and long-time operation to meet customers' demand for extended production time.

Through the network interface of the RS485 of the VFD, the customer is able to use LiteON-Studio software to upload modified parameters. The software can also record wave forms to expedite troubleshooting.

There are multiple operating hardware buttons on the VFD's panel. The tuning process is as easy as setting up a few parameters.

The circuit board is coated to effectively prevent from dust contamination in the factory. This ensures the lifespan of the circuit board.
