Note 1: The 1 speed frequency in disturb operation is set by F2101. Therefore, the 1
through external analog & digital (option) or terminal step. Please use F1002=1, 21.
Note 2: The inching operation before disturb operation is as normal.
Note 3: During disturb operation, since the acceleration/deceleration time can be set by 1
acceleration/deceleration time through control circuit input terminal AD2 and AD3 are noneffective. However,
when AD2 and AD3 are set by terminal stepping function, the terminal stepping function is effective.
When control circuit input terminal is selected by operation signal holding function (F1414~F1421=38), its
function is available.
Note 4: Since the multi-speed in disturb operation mode is set by 1
control circuit input terminal 2DF and 3DF are noneffective.
Note 5: When restart the operation with the functions of speed tracking, alarm auto reset and instantaneous-stop restart,
it will be restarted toward the 1
3) Modulation of disturb operation
st
● The 1 speed frequency and 2
analog input is switched to be non-zero, the corresponding analog input will be modulation command. The maximum gain
(frequency) of analog command will be set by gain frequency (F1402 or F1404 or F1406). However, since the polarity of
analog input is positive, in order to modulate larger and smaller the frequency, a disturb modulation rate (F2237) can be
used to adjust the offset of modulation rate.
2-1) Setting and modulating method
· Use F2236 (analog input switching) to specify the modulation input.
· Use F1402 or F1404 or F1406 (setting of gain frequency) to set a maximum analog input.
Gain frequency implies the switched frequency (modulated frequency) when a maximum analog input is specified
by F2236, i.e. the switching gain corresponding to modulated frequency of analog input. When gain frequency is
decided, the input analog signal will be switched into modulated frequency. This frequency is added by the two
frequencies (1
However, the function codes of 1
frequency can also be negative. I.e. the switched modulation frequency of analog input command tends to be
