US and International modes of operations for VFDs (Variable Frequency Drives) and Speed Controllers

VFDs and motors have two way of operation, in the US we use CW and CCW, in the rest of the world, or INT (International) it is used START/STOP and DIRECTION. These settings can usually be adjusted VFD settings. The chances are that if you purchased the VFD in the US, it came pre-configured for US mode, and if you purchased it overseas, it came in INT mode. Our Breakout boards take Step (PWM) and Direction Control, and pending on the position of the jumpers on the circuit, it activates the relays in the appropriate way.

Why use Ethernet Connection for my Motion Controller?

The Ethernet Connection has many advantages over USB. It is more reliable as Ethernet runs a client-server connection, while USB runs as a Windows Device. If there happens to be any glitch in the communication, you can lose the USB device and it would need to restart it to re-establish the connection. Ethernet can reconnect and establish the connection on the fly. USB requires sharing of the grounds. This is something that you want to stay away from, especially on larger machines or plasmas. There are lots of voltages and EMI noise. All those cables for connecting devices are acting as antennas bringing them back to the electronics. You do not want to send all that to the ground of your PC. The Ethernet connection is capacitive, it does not share the grounds. It is designed to interconnect large networks while not sharing the grounds or creating ground loops on the wiring. This can save you a lot of headaches.

The Analog Output to the VFD is not stable

The issue is related to noise coming back from the analog input terminals on the VFD. They are supposed to be isolated, but sometimes noise finds a way. There are two ways of fixing that: - Use shielded cables for the analog and its ground and ground the shield to the ground of the VFD. - Use a 10uF @25V Capacitor across the analog output terminals on the breakout board.

Can the C-94 be used with Gecko 320X?

You could, but it will be very difficult to wire the error/fault line. I suggest you consider the <a href="https://www.cnc4pc.com/c76-uc300-multifunction-board.html">C76 </a>which is made for this as it can use the <a href="https://www.cnc4pc.com/c34g320-driver-to-rj45-connector-board-g320-drivers.html">C34G320</a>.

How do the inputs work on this board?

<ul> <li>The board has 2 banks of input that could be handled independently and isolated from each other and from the board.</li> <li>Each bank of inputs has bidirectional inputs which activate with a voltage between +5vdc and +24vdc.</li> <li>If the signals that you want to activate the input negative (Open Collector), you would need to feed +5vdc or +24vdc into the COM port of the input bank you are using (COM1 or COM2) and if the signals are positive, then you need to feed the negative of the power supply to the COM and +5vdc (TTL) or +24vdc will activate the input.</li> <li>There are LEDs on all the inputs which light when the input is activated.</li> </ul> <img src="https://www.cnc4pc.com/pub/media/wysiwyg/FAQ/Inputs.png" alt="" width="684" height="243">
