User Manual of A90 Series Inverter The main frequency source A depends on the AI (percentage) * F00.16. AI1 is the 0-10V voltage input; S4/S5 on the terminal block; AI2 is the 0-10V voltage input or 0-20mA current input, selected via the terminals The percentage corresponding to the input physical quantity of the AI terminal is set by the function codes F02.31 to F02.36. 100.00% is the percentage to the set value of F00.16 (maximum frequency). F00.04=4: digital potentiometer setting potentiometer forward or reversely in the monitoring interface, to increase or decrease the Operating instructions for the digital potentiometer: Rotate the digital set frequency. F00.04=6 or 7:
main frequency communication setting The main frequency source A depends on the communication, etc. If the master-slave communication (F10.05=1) is enabled and the inverter works as the slave (F10.06=0), the main frequency source A is set to “700FH (master-slave communication setting) * F00.16 (maximum frequency) * F10.08 (slave receiving proportional coefficient)”, and the 700FH data range is -100.00% to 100.00%, as detailed in Table 0-2 . For general communication (F10.05=0): a. F00.04=6 percentage setting: the main frequency source A is set to “7001H (communication percentage setting of the main channel frequency A) * F00.16 (maximum frequency)”; b. F00.04=7 direct frequency setting:
the main frequency source A is set to “7015H (communication setting of the main channel frequency A)” The 7001H data range is -100.00% to 100.00%, and the 7015H data range is 0.00 to F00.16 (maximum frequency), as detailed in Table 0-2. The final setting of the main frequency source A is also dependent on the DI terminal status: Table 7-1 Detailed Setting of Main Frequency Source A 119 Terminal Function Status Description Priority 11-14: multi-segment speed terminals 1-4 If one is valid, the multi-segment speed mode will be enabled (F08.00-F08.14). 1 51:
switching of main frequency source to digital frequency setting Valid, depending on the digital frequency setting F00.07, the same as the function code F00.04=0 2
