Hey everyone, I trying to use the "fixed frequencies" mode on a micromaster inverter (MM3 serie), here is the operation manuel :https://www.vfds.com/manuals/siemens-micromaster-manual.pdf First of all, you have to know I got back this equipment from a second-hand, so this is not brand new... So I used the reset factory parameters (P944 to 1). I wired 3 switch on DIN1 an DIN2 as 2 different entries for 2 distinct frenquencies, and DIN3 for an inverting rotation button. Then I changed different parameters listed below : - P006 = 2 (fixed frequency) - P009 = 3 (all R/W param) - P015 = 1 (automatic resart) - P041 = 200 Hz - P042 = 100 Hz - P043 = 50 Hz - P051 = 6 (fixed frequencies) - P052 = 6 - P053 = 3 (inverting sw) I have several problems : 1. The equipment does not working until I press the RUN button. 2. Every fixed frequencies are differently setted up but the motor I wired for my experimentation seems work at the same speed whatever frequency I put on P041to 043... 3. The inverting switch does not seems to work. 4. I trust the frequency is supposed to displays on the LCD when the motor is supplyed (like it is setted up by default; P001 = 0) but it's not happening. Please anyone knows this equipment and could help me on this ? Thanks in advance, cheers. Olivier. Attachmentsiemens-micromaster-manual.pdf (745 Downloads) |
