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 ESS or ETHER-MACH, 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 5-24VDC, you can connect sensors NPN, PNP, switches,
capacitive sensors, etc. set jumpers depending on signal voltage.
PORT_1
Jumper position change
PORT_2

4.5 Select JUMPER COM for the 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.
COM = 5V
PORT_2 PORT_1
COM = GND with 5VDC
COM = GND with 10-24VDC
COM = 10-24VDC

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.

DRIVER DISCONNECTION JUMPERS
Nota: 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
-Wiring inputs using an external 10-30VDC power supply to keep input circuit isolated.
-Wiring inputs using an external 5VDC power supply to keep input circuit isolated.

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:
