Variable Frequency Drives for Async Injection Molding Machine
1. Information of Product Model
ES101 Series Variable Frequency Drives are cabinet-type drives, and hence can be located directly on the ground. The cabinet inside is equipped with mains frequency and variable frequency switch contactor. Working status of mains frequency and variable frequency can be manually switched by the key rotary switch on cabinet panel.
The cabinet inside is equipped with analog sampling interface card EPC-IM1 dedicated for injection molding machine.
