I have a special firmware for running the drive over 599hz, but why can I not run above 600hz?

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

Product Line:
Altivar 61 and 71

All products of the Altivar 61 and 71 series

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

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, set Rated Motor Frequency (FrS).  Then define the maximum output frequency by setting the Max Frequency (tFr) and the High Speed (HSP) to appropriate values to increase the output frequency range.
