Issue:
Firmware for running drive over 599hz, but unable to run above 600hz.

Product Line:
Altivar 61 and 71

Environment:
All products of the Altivar 61 and 71 series

Cause:
Has the special software for running the drive over 599hz, but cannot get it to run above 600 hz.

Resolution:
The usual max is around 600 hz. To run above 600hz you will need to adjust some settings in the drive.
In Menu 1.4 Motor Control, you will need to set your Rated Motor Frequency (FrS) to 1000hz, set the Max Frequency (tFr) to 1000hz and then set the High Speed (HSP) to 1000 hz.
