Example:
Example of PLC program for activating the lubrication for the X-axis.
The traverse distance after which the X-axis is to be lubricated is entered in machine parameter
MP4060.0. The duration of lubrication is defined by timer T0 (MP4110.0).
The PLC-output O24 is to be set for the duration of the X-axis lubrication.
In our example, lubrication is activated as soon as the marker M2012 is set. If the lubrication is only
to be activated when the axis is at rest, then this must be taken into account in the PLC-program.
MP4060.0 = 1 000 (approx. 60 m)
MP4110.0 = 100 (approx. 4 sec.).
