X7. F00.04 has the same meanings as AI1-AI4 and X7. 100.00% is the percentage
inputted through F00.18 (Upper Limit Frequency).
F00.17=6 or 7: Communication Setting
For master-slave communication (F10.05=1) and the inverter is slave (F10.06=0)
upper limit frequency is set as “700FH (Main Frequency Setting by Communication) *
F00.18 (upper limit frequency)* F10.08 (Receiving Proportionality Factor of Slave)”.
The range of 700FH is -100.00% to 100.00%. See Table 12-2 for details.
For general communication (F10.05=0)
★
For F00.17=6, upper limit frequency is
“
700AH (communication setting of
upper limit frequency) * F00.18 (upper limit frequency)”.
★ For F00.17=7, upper limit frequency is “7017H (communication setting of
upper limit frequency)
”
The range of 700AH is 0.00% to 200%. The range of 7017H is 0.00 to F00.16
(maximum frequency). See Table 12-2 for details.
F00.18 is the maximum operating frequency after inverter starts and denoted by Fup
(range: Fdown - Fmax).
F00.19 is the minimum operating frequency after inverter starts and denoted by
Fdown (range: 0.00 Hz - Fup).
By changing the function code, user may reverse motor rotation direction without
1. Upper limit frequency and lower limit frequency shall be set
carefully according to the nameplate parameters and working conditions
of the controlled motor. Otherwise, motor, after having worked for a
long time at a low frequency, would lose its service life due to overheating.
2. The relationship among maximum frequency, upper limit frequency and lower
limit frequency: 0.00 Hz≤Fdown≤Fup≤Fmax≤600.00 Hz.
3. When the set frequency is lower than F00.19 (lower limit frequency), the
running mode of inverter is determined through F15.33.
