Hello

I want to know what MD is related to the " lubrication level switch low active" in the sinumerik 802d.
I have to change because theinput isright now lowactive,I have to change to high active, this means that when the oil is low the switch is ON, when the level is good the switch is OFF. I found that the MD 14510 MN_user_data_int [4]=10 is the lubrication on time. thank you.

The question is how could I know the MD is related to the PLC, as an example; $MN_user_data[4] = 10 , in the plc is " LubcOnTime" = 10seconds.

Hi

The input from the lubrication switch is most probably hard coded in the PLC, so you have to connect to the plc and reprogram the logic.

Plz see the attached file for more details.

In the PLC logic you will see the VB45000008 signal.

This signal represents the Parameter 14510[4].
