Disturb Operation Function（F2201=2）
Disturb operation function (F2201=2)
F2236 Disturb modulation analog input switching
F2237 Disturb modulation rate
● The function to periodically set the frequency change and repeat the actions through the pre-set acceleration/deceleration time.
According to the difference between the shaft diameters of front end and terminal end, it is effective for the system desiring to
change the rotating speed.
● For the frequency set in disturb operation, since it is freely modulated according to external analog command, the setting value of
repeated frequency can be adjusted in conjunction with load status.

2) Basic actions of disturb operation
● Please set F2201=2 (disturb operation). No matter what is the control mode of the motor, the disturb operation is
always effective.
● Since there are two settings of frequency value, it must be set according to 1
frequency (F2102).
● When an operation command is input, the both frequencies will be repeated with a sequence of 1
nd
frequency→2
order to prevent twining, an increase/decrease (△F) will be made to the instantaneously set frequency. When 1
frequency is reached, 8

of the acceleration and deceleration time during disturb operation, the frequency is changed through 1
acceleration/deceleration time, furthermore, it can also be changed through 2
