I am trying to run 3 phase Induction motor Rated 0.75 KW, 1.8 Amps, 1440 rpm. with Mitsubishi FR-500E Drive.
When I run motor at 17 Hz ( As process requires ) it takes 2.5 Amps current and getting hot on no load, And when I run at 50 Hz it takes only 1 Amps and runs ok.
Is it not recommended to run the motor on such low frequencies ?
I tried this on other motor with other drive, in that case current not increases as frequency decresses.
Anybody suggest me to run the motor on low frequency with low current, what will the probable causes for the same.
Thanks in advance.
