Introduction
Thank you for the trust you have placed in us by pur-
chasing the mini controller parts set. Before installa-
tion, we recommend reading through these instruc-
tions completely and then proceeding step by step
as described.
Purpose of use
The set of parts described here is supplied by So-
rotec for the construction of a three-axis control for
CNC machines, especially of the „Hobby-Line“ type.
Any purpose other than that stated is not covered by
the instructions.
Tools needed
Common hand tools such as screwdrivers of various
shapes and sizes, wire cutters, etc. should be availa-
ble. In addition, the following tools are required:
• Wire stripper
• Crimping pliers for ferrules
Danger!
Only carry out the work if you are familiar with the
necessary actions familiar and appropriate
tools are available.
Sorotec GmbH assumes no liability for damage to
property or personal injury occurring during assemb-
ly or operation of the control!
Danger!
The electrical structure described here works in the
low voltage range below 60 volts, which is harmless
to humans. Nevertheless, pay careful attention to
possible sources of error (insulation, grounding, ...)
in order to ensure trouble-free operation. Short cir-
cuits in particular can damage parts of the system or
causeres.

Preparing the power stages
Before installation, the output stages must be adap-
ted to the stepper motors used. The eight DIP swit-
ches must be set correctly for this.
Example:
Forthemotorseto󰀨eredbySorotecfortheHobby
Line with a rated current of 4.2 A, the following posi-
tion of the DIP switches is correct for the 542 output
stages from Leadshine:
12345678
On O󰀨 O󰀨 O󰀨 O󰀨 O󰀨 On On
We strongly recommend that switches 1
through 3 are only set as directed, otherwise
the motors may overheat.
However, this switch position is only an example.
When using other motors, the setting must be made
using the tables printed on the output stages (see
Fig. 25).
The rst three DIP switches determine the current
with which the respective motor is operated. The last
four switches in the row control the „resolution“: This
means the number of steps into which a single motor
revolution is broken down.
The stepper motors used carry out 200 steps of 1.8°
per revolution. With the DIP switch setting shown, the
output stage divides these full steps into 8 microsteps
each. This then gives 1600 steps per revolution of
the motor. With a spindle pitch of 10 mm/revolution,
one microstep theoretically corresponds to a travel
distance of 0.00625 mm.

for the Hobby Line motor set
Installing the power stages
Remove the screw terminal connectors (Fig. 26),
they are not needed.
• Plugthefullypreparedpowerampliersinto
slots one to three on the main circuit board. See

For this section you will need: #
12 Pan head screw 31
• Close the cover of the control with pan-head
screws 31 and seal the openings in the bottom
with the remaining stickers.
Finally, establish the connection to the control com-
puter and to the power supply. The controller is now
fully assembled and can be put into operation.

Options
Switchbox
The switch box (EZB.MINI.SBR.01) is optionally
available in the Sorotec shop, with the help of which
230 V can be switched externally via a 24 V signal.
Useful e.g. for the operation of a minimum quantity
lubrication or a chip extraction (designated indiscri-
minately with „Cooling“ in the circuit diagram). For
this purpose, the switch box is connected to the 24 V
and OUT- terminals of AUX1 on the IO module.
A (possibly second) switch box can also be used to
switchthemillingspindleonando󰀨.Inthiscase,the
terminals at AUXS must be assigned.
See wiring diagram sheet 4 and Fig. 30.
Attention!
The sum of all currents at the outputs of the main
board is limited to 2 A by the fuse. It is therefore advi-
sable to supply any existing spindle fan with its own
power supply unit.

LED Module
Fig. 31: Status LEDs show the operating status
The optional LED module is used for optical signaling
of various switching states, such as emergency stop
or spindle ON. The meanings of the individual LEDs
are already marked on the sticker on the front.
• Open the holes for the LED module covered
with the sticker with a sharp knife.
• Plug one end of the connection cable into the
red socket on the module circuit board.
• Fasten the LED module with the enclosed
screws. Fig. 32.
• Plug the other end of the connection cable into
the red socket on the main circuit board as
shown in Fig. 33.
Attention!
Be sure to attach the ribbon cable to the adhesive
sockets with cable ties! A cable that is supplied loose
can easily be damaged by one of the screws faste-
ning the housing cover. Risk of short circuit!

Drive module extension
With the drive module expansion, the controller can
be expanded to include slots for two additional step-
per motor output stages. The function of the additio-
nal channels is determined with jumpers on the main
circuit board: Either ...
• ... as a second drive connected in parallel
to one of the existing axes X, Y, or Z („slave“
circuit). Or ...
• ... as an additional axis A or B, for example for a
rotary table.
Proceed as follows for installation:
• Ifnecessary,rstremovetheexistingother
modules so that you have unhindered access to
the jumpers on the main circuit board (Fig. 35).
• Plug in the jumpers for „CH-A“ and „CH-B“
according to the desired purpose. One jumper
each at STEP and DIR determines whether the
additional stepping motor should run as a slave
from X, Y, or Z, or whether the channel is to be
controlled as an additional A or B axis. See also
sheet 6 of the circuit diagram.
• If necessary, reassemble the removed modules.
• Assemble the expansion module in place using
the spacers and screws provided.
• Connect the standard drive module and the
extension with the enclosed ribbon cable.
• Ensure the correct parameterization of the
additional power stage(s) as described on page
13.
• Plug the additional power stage(s) into place.
Fig. 35: The jumpers on the motherboard
Fig. 36: Extension module for two additional output stages
Note
The jumpers for STEP and DIR of a channel must
each have the same designation in order to ensu-
re a meaningful assignment. For example, STEP
X and DIR X for operation as a slave of X, or STEP
A and DIR A for use as an additional axis A.

IO Module FC / Laser / Alarm
The additional IO module enables, among other
things, the connection of a speed-controlled spindle
for control by the software.
• Ifnecessary,rstremovetheexistingother
modules so that you have unhindered access to
the jumpers on the main circuit board (Fig. 10).
• Put the jumper for AUXS on OPT1 (see circuit
diagram sheet 8 and 9)
• If necessary, reassemble the removed modules.
• Mount the FC IO module in its place above the
standard IO module using the spacer sleeves
supplied. See Fig. 37.
Note
The mounting with spacer nuts enables the ins-
tallation of another optional module above the IO
module FC.
• Connect the module and one of the sockets IOE
on the motherboard with the ribbon cable.
Note
The IO module FC allows the connection of an ad-
ditional LED module to display signals from the
spindle control. The necessary holes in the hou-
sing must be made at your own discretion.
Attention!
A speed-controlled spindle can be connected in vari-
ous ways. Take the time to carefully study the variant
described for your case in the circuit diagram.
Sorotec declines all responsibility for damage cau-
sed by incorrect or improper connection of milling
spindles or other peripheral devices.
