Note 1: The 1st speed frequency in disturbed operation is set by F2101. Therefore, the 1st speed frequency will not be
set through external analog & digital (option) or terminal step. Please use F1002=1, 21.
Note 2: The inching operation before disturbed operation is as normal.
Note 3: During disturbed operation, since the acceleration/deceleration time can be set by 1st and 2nd, the switching of
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 disturbed operation mode is set by 1st speed and 2nd speed, the multi-speed set by
control circuit input terminal 2DF and 3DF are noneffective.
Note 5: When restart the operation with the functions of flying start, alarm auto reset and instantaneous-stop restart,
it will be restarted toward the 1st speed frequency.
3) Modulation of disturbed operation
● The 1st speed frequency and 2nd speed frequency in disturbed operation can be modulated by external analog
command. When 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.
