F00.17=2:AI2
The upper frequency limit depends on AI (percentage) * F00.18.
For the details of AI1 and AI2, refer to the F00.04 description. They have the same
meaning. 100.00% is the percentage relative to the set value of F00.18 (upper frequency
limit).
F00.17=6 or 7: communication setting
The torque depends on the communication and the like.
If the master-slave communication (F10.05=1) is enabled, and the inverter works
as the slave (F10.06=0), the actual upper frequency limit is “700FH
(master-slave communication setting) * F10.08 (slave receiving proportional
coefficient) * F00.18 (upper frequency limit)”, and the 700FH data range is
-100.00% to 100.00%, as detailed in Table 0-2.
For general communication (F10.05=0):
a.
F00.17=6
, the actual frequency limit is “700AH (communication setting of the
upper frequency limit) * F00.18 (upper frequency limit)”.
b.
F00.17=7
, the actual frequency limit is “7017H (communication setting of the
upper frequency limit)”.
The 700AH data range is 0.00% to 200.00%, and the 7017H data range is 0.00 to
F00.16 (maximum frequency). For details, see Table 0-2
F00.18 is the highest frequency allowed after the inverter is started. It is represented
by Fup, ranging from Fdown to Fmax;
F00.19 is the lowest frequency allowed after the inverter is started. It is represented by
Fdown, ranging from 0.00Hz to Fup.
1. The upper and lower frequency limits should be set carefully according to the
nameplate parameters and operating conditions of the actually controlled motor,
and the motor should be prevented from long-time operation at the low
frequency; otherwise, the motor life may be shortened due to overheat.
2. Relationship of the maximum frequency, upper frequency limit and lower frequency
limit: 0.00Hz≤Fdown≤Fup≤Fmax≤600.00Hz.
3. When the set frequency is lower than F00.19 (lower frequency limit), the running mode
is dependent on F15.33.
