[?]: Help solve Altivar 31 OverSpeed fault

Post by nguyenhonghao » Thu Aug 27, 2009 12:18 am

I have a system as follows:

I installed Altivar 31 inverter compatibly with motor's parameters.

Motor works well (current <~ 31A) as frequency <= 45Hz. But when I adjust to increase frequency (~46-50Hz), inverter has fault as OverSpeed (SOF).

Pls help me to solve it!

Thanks.
