Hello sarwan First check that the parameters for setting the command source are set for profibus command source. Here's bellow the set of these parameters. P0700 = 6 ; Control source via Profibus-DP P1000= 6 ; Setpoint source : Profibus-DP P0918 = your drive profibus address. P0922 = sellection of ProfiDrive Telegram. And for sure you have the *.gsd file of the drive. When you put into HW config of the Simatic Manager, You will found a word for controlling speed. This word works as follows: For 0% speed (0% of P2000) = Make the setpoint word = 0Hex. For 100% speed (100% of P2000) = Make the setpoint word = 4000Hex. P2000 is called the reference frequency. So check it also if it's set to the 100% of speed you expect from the drive. if you have send 4000 Hex to the setpoint word, So the inverter will run at a frequency that is written in P2000 if and only if it is greater than or equal P1082 (Maximum frequency) Also, in the following link, you can download FC14. It's pre made function offered from Siemens that controls the MM4 / Sinamics drive via profibus: MICROMASTER 4 & SINAMICS G Function block (FC14) to control an MM4 via Profibus-DP Hope this helps, |
