Group Code Parameter Name Setting Range Initial Unit
Function
group 1
F21 [Max frequency]
- 0 ~ 400 50.00 Hz
F23 [Start frequency]
- 0.1 ~ 10 0.50 Hz

Max Frequency: Frequency highest limit. Any frequency cannot be set above [Max
frequency] except for F22 [Base frequency].
 Start Frequency: Frequency lowest limit. Until a frequency reference is set lower than this,
