Various inclinations can be set by frequency point setting.
The frequency command value on the slave side during inter-drive communication can be expressed
by the following formulas.
If inter-drive communication is not selected (=), point conversion is not performed.
Point conversion is performed only when the command “S” is received.

(Ex.)                               < unit > Frequency unit: 1=0.01(Hz), point setting unit: 1=0.01%
