Make it Spin!
Now that the device is wired, and the connections carefully checked, power on the robot. You should see the SPARK MAX slowly blinking its for a new device the color will be Magenta. If the LED is dark, or you see a different blink pattern, refer to the Status LED guide for troubleshooting.
If you are using a brushed motor, you may see a sensor error. This is expected until you configure the device to accept a brushed motor in the following steps.
Plug in the USB cable and start the REV Hardware Client. Select the SPARK MAX from the Connected Hardware
If you can not see the SPARK MAX, make sure that the SPARK MAX is not being used by another application
. Then unplug the SPARK MAX from the computer and plug it back in.
Before any parameters can be changed, you must first assign a unique CAN ID to the device. This can be any number between 1 and 63. After setting a unique CAN ID, the user interface will refresh and allow you to change other parameters.
Eventually you may set up a CAN network on your test bench or robot. Be sure each device on the network has a unique CAN ID. It is helpful to label each device with its ID number to aid in troubleshooting.
If you are using a NEO or NEO 550, verify that the motor type is set to REV NEO Brushless, Sensor Type is Hall Effect, and the LED is blinking Magenta or Cyan.
If you see a Sensor Fault blink code, make sure the encoder cable is plugged in completely.
If you are running brushed motor, set the motor type to Brushed, sensor type as No Sensor, and verify that the LED is blinking Yellow or Blue.
The SPARK MAX Motor Controller includes a Smart Current Limit feature that can adjust the applied output to the motor to maintain a constant phase current.
To help decide what to set your Smart Current Limit to you can use data from our locked-rotor testing for the NEO (REV-21-1650) and NEO 550 (REV-21-1651)
Motor Type | Suggested Current Limit Range |
|---|---|
40A - 60A | |
20A - 40A |
Warning: setting current limits outside of the suggested ranges listed above may cause severe damage to components
For the SPARK MAX to remember its new configuration through a power-cycle, the settings must be saved. To do this, press the Burn Flash button on the bottom of the page. It will take a few seconds to save, indicated by the loading symbol on the button.
Any settings saved this way will be remembered when the device is powered back on. You can always restore the factory defaults if you need to reset the device.
Before running any motor, make sure all components are in a safe state, that the motor is secured, and anyone nearby is aware. FRC motors are very powerful and can quickly cause damage to people and property.
Keep the CAN cable disconnected throughout the test. For safety reasons, the REV Hardware Client will not run the motor if the roboRIO is connected. If the roboRIO was connected, power cycle the SPARK MAX.
To spin the motor, go to the Run tab, keep all of the default settings and press Run Motor. The setpoint is 0 by default, meaning that the motor is being commanded to idle (0% power). When you press Run you should see the LED go from slow blinking to solid, indicating that the motor is idling.
Slowly ramp the setpoint slider up. The motor should start to spin and you should see a green blink pattern proportional to the speed you have set to the motor. Slowly ramp the slider down. The motor should spin in reverse, and you should see a red blink pattern proportional to the speed you have set to the motor.
