Hai to all i am new in drives. buti should connect 2drives(MICROMASTER440) with CPU-2DP. I got a sample program to connect drives to fc14 in his manual cd. i understand that program but in that program ferquency input multiply with 100 & round the value.after that multiply with16384 after multiply with 5000 why they did like this. L #drive_f_setpoint L 5.000000e+001 >R // setpoint < 50Hz ? JC N004 L #drive_f_setpoint L 1.000000e+002 *R RND L 16384 // 16384 = 4000HEX = 50Hz *D L 5000 wheather the attached program used to change the spped of the drivr or not.

Hi See here MICROMASTER: Function block (FC14) to control an MM4 via Profibus-DP. Follow this logic and you can add profibus slave to profibus network. Micromaster will be only slave. About PZD and PKW - If you want to read 3 (or more) actual values through Profibus, you should use PPO2 (in HW config for Step 7) (4PKW + 6 PZD!) or something like that. But better read manual: https://support.automation.siemens.com/WW/llisapi.dll/csfetch/6586565/MM4_PB_OPI_en_0202_I.pdf?func=cslib.csFetch&nodeid=6586567&forcedownload=true regards |
