2.4.16 Automatic lubrication system
Power source for the lubrication system
The lubrication system for the linear axis is powered either by battery or by cable
from external power source, depending of which option is chosen at delivery. IRC5
can control the lubrication if option 1070-1 for IRC5 is selected. Read more in
Product manual - IRC5.
Handling the signal from the grease level sensor
The grease level sensor reports a completed cycle of the progressive distributor
by changing the pulse twice. The software has to react on the second change of
pulse.
The sensor can be connected either to the robot controller or to a PLC. Code must
be written to handle the signal.
Setting up the lubrication interval
The general recommendation is to start with a time interval of 150 hours or a length
interval of 100 km for the lubrication. These values are to be used for normal room
conditions regarding temperature, humidity and dust. If the conditions are more
severe, shorter intervals should be used.
The flat rails and rack should be "wet" and have a thin oil film but not be soaked.
If the lubrication is correctly adjusted a few floor drips may occur but not much
more.
