Hello everybody, 

I'm using a G120C PN, I was trying to command the Motor(1320 rpm 50Hz) at 50Hz with the Sina Speed block, but I just arrive around 45 Hz not more, is there any parameter that block me? 

Thanks in advance

My guess is your p2000 (reference speed) has ~1200 rpm instead of something higher, like 1320, or the max allowable rpm for the motor and system.

Hi, 

I have tried with the commisioning wizard , but the data seems to be correct (current,voltage,speed,ecc), anyway it should not be a big problem, for my application, I'm not going to reach that frequency(50hz) , but of course , I wanna understand why is working in this way. 

I'll let you know

Hello , 

p1082 = 1320 l/min,  exacly the same of p311 and p2000

How about RefSpeed input of Sinaspeed? Does it match with P2000?

I usually put P2000=2000, P1082=2000 and RefSpeed=2000. So I can speed up a bit over base speed of asynchronus motor in case I need.
