By selecting an operator, you can either switch between main speed and auxiliary speed ([SCHG]
switching with [AA105]=00) or make a command (arithmetic frequency) ([AA105] not equal to 00) on
the basis of addition, subtraction, or multiplication of the two speeds.
 Parameter
(Ex.1) Gain is multiplied.
[AA101]=01 ([Ai1] command)/[AA102]=07 (set [Ab110])/[AA105]=03 (multiplication)/[Ab110]=3.00(Hz)

(Main speed) + (auxiliary speed) is used for the
command.
02
(Main speed) - (auxiliary speed) is used for the

[SCHG] Main speed and auxiliary speed are
switched from each other for the operation.
OFF: Main speed is effective, ON: Auxiliary
speed is effective.
Note The operator needs to be [AA105]=00.
