BOARD DESCRIPTION

POWER TERMINALS AND CONFIGURATION JUMPERS

Power terminal

The board requires an external power supply which can deliver 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.

Source Output 5VDC

Source Output 24VDC

10-24VDC can be sourced to sensors or other cards requiring it.

Input terminals for port_1 and port_2

These terminals support signals 5-24VDC, you can connect sensors NPN, PNP, switches, capacitive sensors, etc.

PORT_1

PORT_2

HIGH SPEED INPUT PORT_2 PIN 2, 3, 4 AND 5
These terminals support signals 5VDC

Select inputs of port_1 and port_2

JUMPER POSITION

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.

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

• Connection with the terminal of output source of 24VDC
• Connection with the terminal of output source 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:

The VFD Alarm will trigger when the contacts are open and the VFD Alarm is enabled.
