7-3 Description of Functions
Arbitrary V/f pattern function
F2003 Arbitrary V/f pattern intermediate voltage 1
F2004 Arbitrary V/f pattern intermediate voltage 2
F2005 Arbitrary V/f pattern intermediate frequency 1
F2006 Arbitrary V/f pattern intermediate frequency 2
Arbitrary V/f pattern can be set when linear V/f pattern is selected as the V/f pattern of F1003.

●
When intermediate voltage 1 & 2 are smaller than the voltage command determined by F1004 (torque boost), a
voltage command determined by torque boost will be for limitation.
●
When intermediate voltage 1 & 2 are larger than the voltage command determined by F1005 (base voltage), the base
voltage will be used for limitation.
●
When intermediate frequency 1 & 2 are smaller than F1103 (starting frequency), the starting frequency will be used
for limitation.
●
When intermediate frequency 1 & 2 are larger than F1006 (
base
frequency), the
base
frequency will be used for
limitation.
Note 1: Trip operation may happen when the output command changes fast, so more attention must be paid to the changes
of settings during operation.
Note 2: Please set F2003=F2004 and F2005=F2006 when only an intermediate point is required.
