User Manual of A90 Series Inverter F00.17=2:AI2 The upper frequency limit depends on AI (percentage) * F00.18. meaning. 100.00% is the percentage relative to the set value of F00.18 (upper frequency For the details of AI1 and AI2, refer to the F00.04 description. They have the same 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 For general communication (F10.05=0): -100.00% to 100.00%, as detailed in Table 0-2. 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 The 700AH data range is 0.00% to 200.00%, and the 7017H data range is 0.00 to upper frequency limit)”. 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. 127
