Dear all,

I have an issue. When i'm using MOVE Hex value from PLC to G120, However, I can't read current value from G120 to PLC. 

How i can get current value?

Thanks and best regards.

Could you be more specific?

What kind of PLC?

How does it communicates with the drive?, i.e. network/protocol/reading over IO channel or DPV1 acyclic

A screenshot of the code you have problem with.

Standardizing the setpoint and actual values

The setpoint and actual values are transferred as normalized values.
The reference values are stored in parameters P2000 to P2006 of the SINAMICS G120.

16384dec = 4000hex= 100% applies here (With 100% referring to the reference value for the transferred variable.)

Example:
If P2000 (reference speed or reference frequency) is 1500 rpm and the drive shall run at a speed of 500 rpm, then 33% or 5461dec must be transferred.

Hi, 

i'm using plc s7 1200 control Drive G120 C, moreover, plc connect to G120  with Profinet communication. i'm only use Move function access with 16 bit.

Hello,

you also need to change the drive settings. You need to parameterize that you want to send the current value via PZD to the PLC.

So first you need to ensure that your telegram has some free PZDs (otherwise extend the telegram length). Then in p2051[x] you can select the values you want to send from the drive to the PLC.

At the PLC side you can read those values then.
