ABB ACS355 Profinet reference speed in Herz
Hello mr Mussolin,
I have an Acs355 with Fena 21
1)Im trying to set the speed and read it back in Hz by the fena profinet module:
I use SCALAR Mode to control speed as Hz,
I set param 1103 to Comm, 1104 to 0, 1105 to 50, param 2007 to 0, 2008 to 50
In the software i give a speed refence value of 20000 and i get 50 hz back(correct)
When i give a speed refence value of 10000 i get 30.5 Hz back (not correct), I should have 25Hz
Can you tell me wich parameters/settings are wrong?
Another point concerning speed in herz:
2)The bit "input.PPO4.SW.AT_SET_POINT" in the ABB profinet block doesn't give back TRUE value when the frequency set is reached...
this bit let me know when the ramp up is ended and the drive is at the set frequency.
What should be the problem/setting?
Thank in advance.

Hi Simone
you will find attached an example of ACS355 programming in ProfiNet, try to check the various parameters and compare any differences.
Hope this help you

Hi Simone
as you described your parameterization seems all right, if you want to try to send the configuration file of your ACS355 I can try it on my test bench, so I can check where the possible error is.
