Mitsubishi FREQROL-SF - Control Circuit and Parameter Setting; Where the Speed Selection Signal Function Is; Provided (SF-OR Card)

3.2 Control circuit and parameter setting
3.2.1 Where the speed selection signal function is provided
(SF-OR card):
(1) Setting parameters
Although the contents of the parameters which are set
by the amplifier are listed in Reference l-2.2(2), only
the parameters relating to the orientation function are
listed in the following.
For instructions of setting parameters, see Reference
1.2.2(l).
