Preface
We thank you very much that you have decided to buy the CNC Controller made by Optimum
Maschinen Germany GmbH.
Changes The illustration of the CNC Controller might in some details deviate from the illustrations of this
operating manual but this will have no influence on the operation of the CNC Controller.
Any changes in the construction, equipment and accessories are reserved for reasons of
enhancement. Therefore, no claims may be derived from the indications and descriptions.
Errors excepted!
We wish you lots of success!

6.1.5 Optional 4th axis on parallel port 1
The main board is equipped with two jumpers. By resetting the jumper the 4th axis at the
connection X 2 is being activated (position 6). The control board at this position has to be set as
master!  “Setting the jumper“ on page 12
Fig.6-2: Front view CNC controller VI - version 2
CAUTION !
When the 4th axis is activated only parallel port 1 can be used. The parallel port 2 is
switched off and can therefore not be used.
6.1.6 Activating the 4th axis
CAUTION!
Unplug the mains plug and wait at least 3 minutes before opening the CNC controller.
This time period is required in order to make sure that all condensers are being
discharged.
Disassemble the upper part of the housing.
In the shown jumper setting the 4th axis is being deactivated. Set both jumpers (J1 and J2) to
the bottom position in order to activate the 4th axis.

other control boards always as slave control boards. The setting is performed over a jumper.
The master board is always exclusively in the slot of the X or X1-axis and the jumper is set as
displayed below.

7.2.2 Operating current and holding current
The control board disposes of two adjustable fields.
Operating current
The operating current moves the step motor. With a direction signal the turning direction is being
changed. The operating current can be set from 2 to 6 A. The type plate of the corresponding
step motor gives the values of the required settings.
Settings operating current:
The current is increasing when the potentiometer is turned clockwise. The current needs to be
set according to the used step motor. If the current is set too high, the running properties will
degrade and there will not be more power ! Please do not overturn the potentiometer.
Setting step motor 2,2 Nm about 75%
Setting step motor 4,2 Nm about 100%
Setting step motor 8 Nm about 100%
When the red control lamp (red LED) is flashing, the operating current
is set too high and needs to be reduced. Also refer to,
 “The red LED on the CNC controller flashes or flickers.“ on page
17
Holding current
The holding current provides a save hold during the operation break and a save hold of the non-
moving axes at the time of operation.
Setting holding current:
The holding current is increasing by turning the potentiometer clockwise. In most cases a setting
of about 30% is sufficient. In case of heavy chipping and when a ball screw spindle is being
used, the setting needs to be set a little higher at about 40%.
CAUTION!
If the holding current is set too high, it will lead to unnecessary heating-up !

7.3.2 Operating current and holding current
The control board disposes of several jumper positions which need to be correctly set, before
installing the CNC controller.
Operting current
The operating current moves the step motor. Over a direction signal the turning direction is
being changed. The operating current is determined over the jumper. The type plate of the
corresponding step motor indicates the values of the required setting.
Setting operating current jumper 3 to 5 :
The current has to be set on the used step motor over the jumper. If the current is too high it will
lead to a degradation of the running performances and does not perform more power!
J3, jumper 3 - for step motor 3 A
J4, jumper 4 - for step motor 4 A
J5, jumper - for step motor 6 A
When the red control lamp (red LED) is flashing, the operating current is set too high. Check the
correct jumper position with the used step motor.
 “The red LED on the CNC controller flashes or flickers.“ on page 17
Holding current
The holding current provides for a safe hold during the processing breaks and a safe hold for the
axis which are not moved at the moment of processing.
Setting the holding current:
Over jumper Hold Torque 75% or 50%
It is advantagous to start with the setting 50% holding current!

8.2 Definition of the axes on the machine tools
For machine tools right-turning, right-angled coordinate systems are being used. Herewith the
moves on the machine are described as relative moves between the tool and the workpiece.
The origin of the coordinate system is the point of origin of the machine. Here all axis are at the
position zero. This point only determines a reference point.
Fig.8-7: Coordinate system lathe and milling machine
9 Malfunctions
9.1 The red LED on the CNC controller flashes or flickers.
The operating current is set too high.
Slightly turn back the operating current on the potentiometer anti-clockwise.
The correct function is always given if the blue LED flashes when the corresponding axis is
being triggered.  “Potentiometer control board V2“ on page 11
9.2 All axes are no longer triggered.
In case of a short circuit or excess voltage or in case of a defect on the control board, all 3 axes
will be switched off ! This way a damage of the workpiece will be avoided as far as possible.
The red LED shows which axis is concerned.  “Replacing a control board“ on page 14
9.3 Step motor does not run
Possible cause: The CNC controller has no tension.
Remedy: Is the illumination of the main switch of the CNC controller off? Check the plug and
the fine-wire fuse on the CNC controller.
Possible cause: The machine is not cleaned from corrosion protection agent. Therewith the
breaking-loose point is too high.
Remedy: Remove the corrosion protection agent on the machine, clean the machine and grease
it again.
Possible cause: The terminal strips on the machine are fastened too tight. Therewith the
breaking-loose point is too high.
Remedy: Better adjusting the terminal strips.
Possible cause: The transverse rate is set too high, motor current is selected too low.
Remedy: Reduce transverse rate, increase motor current a little.
