1 Safety
1.1 General
Read the entire manual before working with the product. The manual con-
tains important information for your personal safety. The manual must be
read and understood by all persons who work on the product in any of the
product life phases.
Read the Safety chapter of the superordinate manual before working with the
product. It contains important information for your personal safety. The
chapter must be read and understood by all persons who work on the prod-
uct in any of the product's phases. You are obligated to implement the infor-
mation and warnings it contains, wherever they pertain to the product.
WARNING
Automatic startup
During work on the product, there is danger of the machine starting up auto-
matically. This can lead to severe or fatal injuries!
Before working in the danger area:
• Secure vertical axes (if equipped) against falling.
• Switch off the superordinate main power supply. Secure it against being
switched on again (main switch for the complete system)
• Before switching on the system again, make sure that no one is in the dan-
ger area

2 Design, function
2.1 Design
The automatic lubrication system of the drive module consists of a small lubri-
cant dispenser with progressive distributor with several outputs. The auto-
matic lubrication system lubricates the guideway and rack of the equipped
axes automatically. The lubricating pinion unit lubricates the rack. The wiper
and lubrication unit lubricates the guideway.

2.2 Function
Lubrication is an important part of the maintenance.
The following are the most important elements for achieving effective lubrica-
tion to optimize productivity:
• Lubricant dispenser
• Lubrication point
• Lubrication quantity
• Lubrication cycle
MEMOLUB is a powerful (25 bar) and precise electro-mechanical lubricant
dispenser. The lubrication is centralized and automated. The lubricant is con-
tained in a cartridge. With the progressive distributor, several points can be
lubricated simultaneously.

2.2.1 Functional description of progressive distributor
The progressive distributor evenly distributes the incoming lubricant to all
outputs that are in use. If an output is closed, the output on the opposite
side from it will discharge double the quantity of lubricant.

B Main line E Ring groove
C Right changeover line F Lubricant
From the main line, the lubricant flows through the right-hand ring groove of
piston III. The changeover line moves piston I to its right-hand end position.
The lubricant displaced by piston I goes through the left changeover line and
exits at output 6.

After piston III has moved, lubricant flows to the right side of piston I and
pushes the piston to its left-hand end position. The displaced lubricant exits
through output 3. The progressive distributor continues to follow the func-
tional sequence as described, until all outputs have been supplied with lubri-
cant.
As long as pressure is generated by the lubricant, the entire procedure keeps
repeating in the progressive distributor.

2.2.1.1 All outputs open
The progressive distributor evenly distributes the incoming lubricant to all
outputs. The opposite outputs are operated by the same piston. For the iden-
tical conveying volume to be output at the opposite outputs, the headless set
screw must close the connecting passage of the two outputs. The progressive
distributor is normally supplied ex works with the headless set screw fitted.

2.2.1.2 Output closed
The connecting passage between opposite outputs is closed with a headless
set screw ex works. In some cases, outputs on the progressive distributor
may be closed. The headless set screw must then be removed. As a result, the
piston conveys twice the volume to the open output.
NOTE
Lubricating film missing
If an output is closed without removing the headless set screw from the con-
necting passage between the opposite outputs, the progressive distributor
will not work. The piston cannot move. A missing lubricating film on guide-
ways and racks leads to damage to the product. This results in operational
failure.

3 Operation
3.1 Setting the lubrication cycle / lubrication
quantity
The following table shows the lubricant consumption when standard settings
are used.
You can find additional settings in the third-party documentation from
MEMOLUB.
Lubrication cycle The lubrication cycle is 48 hours long. Perform lubrication work at the latest
when the first signs of tribocorrosion (reddish discoloration of the track)
show.
Emptying time of
the cartridge
The emptying time was measured using the black dosing ring. This is the de-
fault setting at Güdel.
Cartridge 120 ml Cartridge 240 ml Cartridge 480 ml
12 months 24 months 36 months
Table3-1 Emptying time of the cartridge
Lubrication quan-
tity
Per lubrication cycle, the lubricant dispenser discharges the following lubrica-
tion quantity to the progressive distributor:
Lubrication quantity [ml] Lubrication quantity per output
on the progressive distributor
[ml]
0.635 0.1015
Table3-2 Lubrication quantity per lubrication cycle: at the lubricant dispenser / at an output of the progressive
distributor
The lubrication quantity per output on the progressive distributor is usually
equal. However, closing an output affects the lubrication quantity per output.
