DEFAULT TO 60HZ
The setting of this parameter selects the drive operating frequency. It affects those parameters whose values
are dependent upon the default base frequency of the drive. Settings will only be updated following a
“restore macro” operation.
The default is 50Hz (6511 keypad = 0 , 6901 keypad = FALSE).
Refer to Appendix D: “Programming” - Frequency Dependent Defaults.
