87hz drift with FR-E700

3 posts in this topic

Hallo. Im currently in a project, where some motors have to run 87hz drift to obtain full momentum, above the normal 50hz After searching a on the subject. I found that: The motor should be 230/400V and mounted in delta. The inverter should be set to 400V. At the moment the inverters are set to 230V because at 400V they tripped. But it sounds like they are struggling a lot. As this is very new to me. Id like to hear some advice on this if anyone have had experience with it.

What exactly do you have? A 400V inverter or a 230V inverter? You cannot switch between input voltage on the inverters, they are either 230V or 400V. Do you have the full name of the inverter (as printed on the side)?

Please attach full nameplate data of both the motor and the inverter. A close picture of both would work.
