How can the frequency for the ATV58 unit to run above 60hz?

The high speed (HSP) can not be set higher than the Maximum Frequency (tFr).
tFr is in the drC menu. Increase this value to about 20% greater than the desired high speed.
The maximum value for tFr depends on the setting for switching frequency (SFr)
See the keypad programming guide for additional assistance.
