Sinamics V20 Max frecuency

Hello,

I'm trying to increase  V20 maximum frecuency over 50Hz but i'm not able to do it.

Reading manual, i understand that p1082 should be used to set maximum frecuency. Then I change it from 50Hz to 70Hz or more (for example) and I checked that this parameter is stored.

The problem is that when I set 10Volt to V20 AI it set its frecuency to 50Hz.

Anybody can help me?

Thank you!

V20 current parameters:

Cn002
AP030

p0304:  400V
p0305:  1.89A
p0307:  0.55kW
p0308:  0.82
p0311:  1311rpm

p700:   2
P701:   0
P702:   0
P703:   0
P704:   1

p1000:  2

Hello,

thank you very much! Now it's working.

Can you clarify main difference between P2000 and P1082?

Thank you

Those are completely different parameters.

P2000 is the reference frequency. It's used for scaling. Whenever there is a percentage value that has to do with frequency it is multiplied by P2000. F.e if your setpoint is 60% it's 60% of P2000.

If your setpoint is 100% (which can be 10V, 4000H, 20mA or whatever) it's multiplied by P2000. Therefore if P2000 = 50Hz you can't really go above 50Hz because 100% * 50Hz = 50 Hz.

When you change P2000 to f.e 100 Hz and set the setpoint to 100% you get 100% x 100 Hz = 100Hz.

But, if your max frequency P1082 is still P1082 = 50Hz you won't be able to go beyond that.

It's all in the operating instructions.

Hi,

I hope its fine to follow this conversation.

i have the same issue with our V20 is it the same P2000 for Ref. Freq?

Kindly help please?
