User Manual of EM730 Series Inverter This function is mainly conducive to parameter display, especially during operation. output frequency (F18.00), set frequency (F18.01), output current (F18.06), output voltage By default, several common items are included in the cycle display queue, including the (F18.08) and DC bus voltage (F18.09). Please set the corresponding bit to 1 to select other display parameters and 0 to hide the selected parameters. ★ Some bits of the function codes for display parameter selection are reserved. Please set them carefully.
Where several inverters need to run with the same parameter settings, we can debug one inverter first, set it to F12.03=1 to upload the set parameters to the keyboard for temporary storage and finally set the other inverters to F12.03=2 (Do not download motor parameters or F12.03=3 download motor parameters) to download the parameters to these inverters. This function can be applied to quickly set the parameters of several inverters. Even if some parameter settings are different, this function can be applied to set multiple function codes before setting by other means. The inverter output is mostly displayed in the frequency form.
To set the current load speed (F18.13), you can change the current parameter from frequency output to speed output based on the actual working conditions, so that F18.14 displays the current load speed correctly. If F12.09=30.00 (related to the number of motor pole pairs, transmission ratio and the like), the output frequency (0.00 to 50.00 Hz) corresponds to the load speed (0 to 1500 rpm). 260 Function code Function code name Parameter description Unit Default setting Attribut e Mailing address F12.03 Parameter copying 0: no operation 1: parameter upload to keyboard 2: download parameters to inverter (F01 and F14 groups do not download) 3:
