micromaster 440 control

2 posts in this topic

I have a driver, siemens micomaster 440. I want to control a 3phase induction motor with this inverter via PC using MATLAB. I think there are a few method for this such as profibus, RS-485, USS etc. Which one is better? And I will send data which involves speed,direction, start, and stop info. which data sholud I send? I don't know structure of data. For instance, 1. byte = direciton 2.byte = speed .... .... n.byte.

I think Profibus is a good way. USS is slow, used for program the drive with drive software. You'll need to add profibus adapter on the drive. see att. for profibus documentation. wish I help... gsg_mm4_profibus.pdf MM4_PB_OPI_en_0202_I.pdf
