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.

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">

How does the Spindle Control work on the CNC4PC Multifunction Breakout Boards

The relays are not directly tied pins in the configuration, as it is the breakout board that is driving the relays based on the step(PWM) and dir received from the controller and the US/INT Mode selected to drive the spindle. Please check this: https://www.cnc4pc.com/faq/article/us-and-international-modes-of-operations-for-vfds-variable-frequency-drives-and-speed-controllers Note that the installer or configuration instructions include configuring the spindle. You really only have to set the max spindle speed of your spindle. Then on the board, you need to set the VFD logic, US or INT. If you purchased a VFD in the US, then most likely it is configured to US Mode, that is to receive FOR and REV signals. That is Relay1 will activate in the presence of PWM, and relay 2 there is the presence of PWM and the DIR signal is active.

Using Relays 1 and 2 as General-Purpose Relays

Relays 1 and 2 are intended to be used for controlling the VFD or Speed Controller and are intended to activate the FOR and REV signals (US MODE) or the ON/OFF and CW/CCW (INTernational MODE). But if you do not need to control the VFD, but intend to use them for general-purpose, it is doable. Here is what you have to do: <ul> <li>Go to Motor Output and unassign pins 14 and 16 on port 1 from the Spindle Control.</li> <li>Set Jumpers for US/INT Mode to Jumper1 = INT and Jumper2 to US.</li> <li>You can then pins 14 and 16 for activating Relays 1 and 2.</li> </ul>

Full of Features

• Can ship with the Ethernet Smooth Stepper Motion Controller installed
when purchased as a bundle.
• Built-in PWM-Based Speed Control and Two Built-in Electromechanical
Relays with NO and NC positions for spindle control.
• The system monitors:
- E-Stop
- Safety Charge Pump.
• Electromechanical Relay with NO and NC positions for general purpose
(Port_2 16 or 17, jumper-selectable).
• Microcontroller based SCHP (Safety Charge Pump).
• Optoisolated inputs working at 5-24VDC.
• Uses a single +24VDC to power the system. It generates the isolated voltage for the spindle control circuit and +5vdc for circuits using TTL
logic.
• Status LEDs on all input and output connections.
• DIN Rail mountable.
• Open Collector Outputs pins 1, 14, 16, 17 on Port 2.
• Screw-On connections for all terminals.
• Status LEDs for enable.
• The ENABLE Output of the C25XP is now tied to LPT3. So that relay or
breakout boards connected to LPT3 will be enabled/disabled with the
C25XP.
• Available installers and configuration files that configure all the functions
of the board
