I just got a Sumitomo Heavy Industries AF3000 VFD for free. It is 5HP w/ a digital key board on the face of the drive. I am having trouble understanding the settings listed below. Also, if I change the Output frequency do I need to change other parameters such as the "Max. Voltage Output Frequency" or will the VFD adjust itself? Also, what do these settings all mean? I just want to be able to vary the speed of the 3 phase motor on my lathe. Maximum Hz is apparently 400. Also, even though this is a digital setup can I install a pot to adjust the frequency? Any help greatly appreciated. Thanks, Steve
All listed settings are "Factory Preset".
Max Output Frequency 60.0 Hz Max Voltage 200.0 V Max Voltage Output Frequency 60.0 Hz Intermediate Output Frequency 1.5 Hz Intermediate Output Frequency Voltage 11V Min Output Frequency 1.5 Hz Min Output Frequency Voltage 11V Output Volatge Limiter Selector 0000
