| 1) the electrical part of the automatic packaging | | | | Food packaging machine applications used in |
| machine generally consists of the following | | | | transmission although relatively simple, but the |
| components: | | | | dynamic performance of the high transmission |
| A) the main control circuit speed sensorless | | | | requirements, system requirements follow the |
| vector frequency by a programmable logic | | | | fast dynamic performance and precision |
| controller (PLC) controls the composition of the | | | | high-speed stability. Therefore, the inverter must |
| core; | | | | be considered dynamic technical indicators, use |
| b) temperature control circuit consists of | | | | high-frequency converter to meet the |
| intelligent temperature controller, solid state relays, | | | | requirements. |
| thermocouple elements such as composition, | | | | ABB sensorless vector inverter, to meet the |
| temperature control is precise, intuitive display, | | | | requirements of packaging machine, because it |
| easy to set; | | | | has the following characteristics: |
