5.10 Upper limit and lower limit frequencies

• Function
Programs the lower limit frequency that determines the lower limit of the output frequency and the upper
limit frequency that determines the upper limit of that frequency.
Short across the R-CC terminals: reverse rotation
* Reverse rotation is valid if short across the F-CC terminals and R-CC terminals at the same time.
This function is valid only when
