CIMR-F7U2015 Yaskawa 

 

3G3RV-A2150 Omron

20 HP, Serial F7

The F7 drive was the Industrial Workhorse of adjustable frequency drives. It was intended to handle every conventional drive application found in the typical industrial manufacturing plant from simple variable torque pumping to sophisticated networked material handling. The F7 / Configured package provided an F7 drive in a NEMA Type 12 or NEMA 12 FVFF enclosure, with space for factory-mounted and wired options, such as reactors, filters, circuit breakers, fuses, network communications and I/O cards, etc.
