Hello everyone.

I am currently working with the frequency converter SEW MC07B0055.
The converter is connected to the Profinet network via DFE32B V1.4.
There is only one telegram for this converter in the TIA Porta - (1-3PD).

Questions:
Are there any other gsdml-files for this converter, where I can choose several telegrams?
For example, I want to get the value of the current in the telegram.

Is there anything similar to FREE-Telegrams like Sinamics?

Thanks.
 
Hello.
Everything needs to be done in a frequency converter.
The telegram size does not change.
But if I need to look at a lot of data, then how to be?

hi petr,

no way for free telegramm-data.
what you want to do? the mcb07 per default only supports 3pd
(so only three words available)
if you like to customize it you have to programm the functions in ipos:

So, depends on what you want to do?
the mcb07 should be good for velocity applikations.
 
Hi, hans_a1977
Thanks you for the quick response.
Speed control.
I have had experience with Sinamics S/G.
I logged data from Synamics (actual speed, actual current, power, error code, warning code, temperature ....)
I created FREE telegram in Sinamics.
I liked the customer too.

I would like to do this on the SEW.
 
in a short:
youve got 3 words - come from sps -
first one is control-word
second one is velocity
third one is free to choose in the inverter (parameter 870), normally a accelleration/deceleration

control word is:
first bit : non-release / release bit
sec. bit : release / halt bit
third bit: release / stop bit
... (see in chapter 7)

so to set the the inverter free you have to write a decimal 6 into first word! (all releases have to be there)
in the second word you have to write a veloctiy
-> inverter will "drive"
 
I want to receive information from the converter.
This is the main thing for me.
(actual speed, actual current, warning code, error code, power, temperature...etc)

How to get the error code in the telegram?

and now you need this one:
https://download.sew-eurodrive.com/download/pdf/11697415_G12.pdf

on page 462 (error codes)

So if your status word in the sps (word1, bit5) is set, youve got an error.
the code is then in byte 2. (bit8-16)
look it up on page 462 and youve got your error...

if the bit is not set, youve got your status code ( not an error code )

hope this helps.
