BOARD DESCRIPTION
POWER TERMINALS AND CONFIGURATION JUMPERS
4.1 Power terminal
The board requires an external power supply which can deliver 10-24VDC@700mA to power
the logic of the board and the UC300, but keep in mind that each output can deliver up to
500mA and if powering other breakout or relays boards. So, you will need to add all the
expected power consumption.

___________________________________________________________________________
4.2 Source Output 5VDC
4.3 Source Output 10-24VDC
10-24VDC can be sourced to sensors or other cards requiring it.
4.4 Input terminals for port_1 and port_2
These terminals support signals 10-24VDC, you can connect sensors NPN, PNP, switches,
capacitive sensors, etc. set jumpers depending on signal voltage.
PORT_1

___________________________________________________________________________
PORT_2
HIGH SPEED INPUT PORT_2 PIN 2, 3, 4 AND 5
These terminals support signals 5VDC
4.5 Select inputs of port_1 and port_2
Set the Jumper to COM = +5VDC, GND or 10-24VDC to determine the common for the input
signals to be used.

___________________________________________________________________________

___________________________________________________________________________
JUMPER POSITION
5.1 Selecting the SCHP operation mode
The Safety Charge Pump uses pin 17 on port 2. When the SCHP is enabled on the board, then
the output of the terminals will be active while the Safety Charge Pump signal is present and
inactive while the SCHP is not present.
1-2: SCHP ON 2-3: SCHP OFF
Note: also, that Relay3 on can also be tied to pin 17 or 16 on port 2. If the jumper is set
to be tied to pin 17, then the relay will activate while the system is active. This can be
ideal to control power to DC servos or to handle servo brakes. Or enable/disable any
other feature that is associated to the system been active.

___________________________________________________________________________
5.2 Jumper configuration driver enable
When you need to use the Driver enable to ON put the jumper, if you need it OFF remove the
jumper
1-2: Driver enable ON 2-3: Driver enable OFF
5.3 Jumper configuration driver fault
When you need to use Driver Fault to ON set the jumper, if you need to OFF remove the
jumper.
1-2: Driver fault ON 2-3: Driver fault OFF
5.4 Configuration jumper pin 16 or 17
1-2: PIN16 2-3: PIN17

DRIVER DISCONNECTION JUMPERS
Note: 1-2: Cable disconnection detection.
2-3: No cable disconnection detection.
This configures how cable disconnect is to work. Set according to C34 board manual.
E-STOP TERMINAL
Connect an E-STOP push button as is shown in the below images.
Pin 10 port 1 is used for E-Stop. Since this board controls the enable line, and the
enable line is the one responsible for notifying the controller of the e-stop condition, the
user does not have a direct access to the pin itself, just to the e-stop terminal on the
board. The E-Stop terminal is tied to the enable line and will trigger the e-stop. A fault
or E-Stop triggers a low for 5 seconds to notify the controller of the fault condition, then
resets to high again.

___________________________________________________________________________
TYPICAL CONNECTIONS
-Connection with the terminal of output external of 24VDC
-Connection with the terminal of output external of 5VDC

___________________________________________________________________________
LED INDICATOR
The standby LED lights indicate that the system is ready but disabled. When Status
LED, (Green LED) lights, it indicates that the system is enabled.
There are 4 possible error sources: a driver fault, E-STOP error, SCHP error or VFD
alarm. A LED will light close to the source of the fault.
VFD Connection and configuration jumper

The VFD Alarm monitoring feature can be enabled or disabled:
