DCC1000 User Guide

Getting Started

Welcome to the DCC1000 user guide! In order to get started, make sure you have the following hardware on hand:

• DCC1000 DC Motor Phidget
• VINT Hub
• Phidget cable
• USB cable and computer
• Power supply (8-30V DC)
• DC motor

Next, you will need to connect the pieces:

1. Connect the DCC1000 to the VINT Hub using the Phidget cable.
2. Connect the motor to the Phidget's output terminals.
3. Connect the VINT Hub to your computer with a USB cable.
4. (Optional) If your motor has an encoder, connect it to the encoder port on the DCC1000.
5. Connect the power supply to the power terminals.

Now that you have everything together, let's start using the DCC1000!

Using the DCC1000

Phidget Control Panel

In order to demonstrate the functionality of the DCC1000, the Phidget Control Panel running on a Windows machine will be used.

The Phidget Control Panel is available for use on both macOS and Windows machines.

Windows

To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

macOS

To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.

For more information, take a look at the getting started guide for your operating system:

• Getting started with Windows
• Getting started with macOS

Linux users can follow the getting started with Linux guide and continue reading here for more information about the DCC1000.

First Look

After plugging the DCC1000 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

• Serial number: allows you to differentiate between similar Phidgets.
• Channel: allows you to differentiate between similar objects on a Phidget.
• Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

The objects associated with the DCC1000 are as follows:

• Current Sensor: Measures the amount of current flowing through the motor's coils.
• DC Motor Controller: Controls the velocity and current of the motor, and the on-board fan.
• Encoder Input: Reads encoder input so you can implement closed-loop control of the motor.
• Temperature Sensor: Measures the temperature of the DCC1000 so you can tell if it's overheating.
• Voltage Ratio: Measures the sensor input of the "Analog In" port of the DCC1000. Intended for use with feedback potentiometers that some motors and actuators are equipped with.

DC Motor

Double-click on the DC Motor object, labelled DC Motor Phidget, in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Drag the Target Velocity slider from -1 (full reverse) to 1 (full forward) to make the motor move.
• Manipulate the Acceleration slider to increase/decrease the amount of time it takes the DC Motor to reach a target velocity.
• Manipulate the Current Limit slider to limit the amount of current provided to the motor. Higher current means more torque, but more power consumption.
• Manipulate the Braking Duty Cycle slider to change how hard the motor brakes.
• Manipulate the Current Regulator Gain: see the technical section for details on this.
• Turn the fan on and off by selecting the fan mode. Auto mode will have the fan turn on whenever the controller starts to heat up.

Current Input

Double-click on the Current Input object Current Sensor in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.

Encoder

Double-click on the Encoder object, labelled Encoder Input, in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Position Change: the number of ticks (or quadrature cycles) that have occurred since the last change event.
• Time Change: the amount of time in milliseconds that has elapsed since the last change event.
• Position: the total position in ticks relative to where the encoder was when the window was opened.
• Index Position: the position where the index channel was last encountered. Some encoders do not support index, check your encoder's datasheet for more information.
• Velocity: the average velocity in rotations per second. A CPR must be specified to enable this functionality.
• Specify a counts per revolution (CPR) value to enable velocity calculation.
• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• Modify the IO Mode with the drop-down menu. For more information on IO Mode, see the technical section.

Temperature Sensor

Double-click on the Temperature Sensor object , labelled Temperature Sensor, in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• The measured temperature can be seen next to the Temperature label. Cover the board with your hands to see the temperature quickly rise.

Voltage Input

Double-click on a Voltage Input object in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• If you have an analog sensor connected that you bought from us, you can select it from the Sensor Type drop-down menu. The example will then convert the voltage into a more meaningful value based on your sensor, with units included, and display it beside the Sensor Value label. Converting voltage to a Sensor Value is not specific to this example, it is handled by the Phidget libraries, with functions you have access to when you begin developing!

For more information about Voltage Inputs, check out the Voltage Input Primer.

Interfacing Encoders

The DCC1000 can connect to any of the encoders we sell without any modification just by setting the EncoderIOMode property to Push-Pull . If you're trying to use your own encoder, you may need to change the IO mode to Open Collector or Line Driver mode. Have a look at the Encoder Primer for more details on what to use.
