Introduction
This manual contains instructions for mounting, using the breakout board
It is imperative to connect 230V connections by a knowledgeable
electrician.
These operating instructions have been prepared with care If you still find
errors, we would be grateful for an indication

Description of the breakout board
The breakout board enables the operation of up to 4 stepper motor or servo
output stages on the UC400Eth
For this the control Software Mach3 / UCCNC (not included) is used The board
has various inputs and outputs that can be individually set as many different
configurations are possible Depending on the selected configuration,
additional functions are available, such as control of a frequency converter via
an analog signal of 0-10V or 0-5V, reference switch, spindle direction relay, up
to 3 relay outputs and one Charge Pump
All signals are protected by Optocouplers All machine-side signals are rated
from 5V to 30V, ensuring robustness and compatibility even with industrial
sensors (PNP SENSORS)

Commissioning
Installation of the UC400ETH
The UC400ETH is screwed onto the 4 spacer bolts with M3 screws
The operating voltage is supplied via the Breakoutboard

Inputs
Each input port is provided with its Pin number
in Mach3/UCCNC at Ports & Pins has to put a hook in Active Low
When the limit switch is actuated, it internally switches to ground and Mach3 detects a
response at the input PNP sensors switch with the switching voltage so they are also direct
connected

Outputs
Like the input port, each output port is also provided with a pin number and an associated *
(output)
example
X32-1 is Number 6 = Port2/Pin6 and
X32-2 is Number 6* = Port2/Pin6
For 5V sensors, relays or similar loads you can put a bridge of 5V on the respective pin
number, so you can use a power supply
For switching max 50mA per output are available. If you need higher currents for switching
you can connect inexpensive relay modules.
You can connect to any pin without * a direct voltage, max to 30V

Set spindle
Port 1 / Pin 1 is the analog output for the spindle speed
A VFD frequency inverter for the analogue signal can be connected to the spindle output Via
jumper 1-2 = 5V or bridge 2-3 = 10V output signal at bridge
The Potentiometer R13 should not be adjusted he is set so that at 5V PWM output from the
PC comes a 10V analog signal

Relaisoutput
There are 4 Relay Outputs up to 230V / max 10A (2,2KW at 230V) available
PORT 2  Pin 1,14,16 oder 17
Attention: do not connect switching power supplies because they have a very high inrush
current, the relay contacts may be defective

Charge Pump
This setting can be enabled or disabled
If the jumper is set to 1/2 the board will be activated without protection and all will remain
Tensions and controls are maintained even if Mach3 makes a reset
If the jumper is set to 2/3, the breakout board will be controlled by Mach3 via the 12 5Khz
signal That is, only after the reset of Mach3 is deactivated, the board is active All
components are supplied with 5V or 12V For this you have to make the following settings in
Mach3:
