 Errors in the field that this tab is in Pololu Simple Motor Control status Center identifies problems that can stop your engine. |

A simple motor controller has several functions that troubleshoot a motor failure. These are known as memories and can help protect your entire project from damage. Whenever you have a problem with your controller, the first thing you should do is check what errors (if any) usually occur. You can get information about errors:
- Check for any error field in the status bar of the Simple Motor Control Center. This is recommended because it gives you the most complete documentation, a constant count of the number of error messages not too long ago.
- Run the command line utility (just sort -s
smccmd on the command line). - The view is carried out by means of a red LED on the instrument. It lights up as soon as errors occur when stopping your current engine. PC
- Write software or use just about any miccontroller for sending the serial Get Errors command.
- Calculation of the ERR voltage on the spindle using a microcontroller. This pin is connected to a really red LED, so it should be high (3rd if 3V). Otherwise, a big mistake will be made - stop the engine and decrease (0V).
- Secure boot violation. Secure Boot is a feature that helps prevent unexpected kernel startup. This feature is enabled by default, but you can disable it in the Advanced Settings tab. The behavior of Safe of Start depends on the input mode you normally use. Serial / USB

In input mode, the "Secure Boot Violation" error always occurs when all other errors stop the kernel. After all other bugs have been fixed, the common way to clear the Secure Boot Violation error is to continue pressing the Resume button (which issues a reliable onboard USB command) or by using absolute serial control.
In analog or RC advisory mode, error SaThe fe-Start Ticket always occurs when the engine stops due to an error, AND those inputs that control the engine speed are not near these neutral positions. This is to avoid a situation where an error can occur that will stop your sickle-shaped system (for example, to clear a Safe Start violation, move all information that controls the speed of the entire machine. Motor to neutral position (sum of absolute values in relation to their scaled values should not be at all 8%).
- Mandatory Invalid: Channel This error occurs when the required RC and analog channel are invalid. This error will help ensure that your machine shuts down if you accidentally remove your joystick, potentiometer, or remote control phone. The channel is invalid if it is disabled or if its actual value exceeds the capacity. The channel is necessary if it controls the speed that the motor can use or can use as a limit switch or killer. Defaultno channel is monitored because the input function is serial and no limit or stop switches have been configured. You can view the Input Options tab to see what channels you might need. Required and invalid channels are highlighted in red in the Input Channels field on the Status tab so you can quickly see which channel this error occurred on.
- Command Timeout: This error occurs when you control a motor with a microcontroller or PC (input mode: serial / USB), but the timeout (configurable) has also expired and the operator has not received valid serial or USB commands. The purpose of this advisory error is to make sure that in the event of a controller software failure, your engine will shut down if the communication line is also interrupted. Any valid serial port erase commands will indicate that sensor has failed. Built-in USB instructions for adjusting the speed and exiting Secure Boot also eliminate this wonderfulmy mistake. By default, this error is considered disabled, but it can be set in advanced settings by setting the command timeout value to a value other than zero.
- Limit switch / switch: This error occurs when a limiter or emergency stop channel stops our engine. In particular, this happens in three cases: when this safety switch is active, when the front limit switch is active AND the target speed is positive, when the rear limit switch is simply active AND the target speed is usually negative. The Limit / kill switch will be considered active if its actual scaled value is greater than 50%. If the person is using the perimeter switch and your input mode is also Serial / USB, the client will need to check the counter column in the status tab to see this error because Serial / USB mode sets the target speed to 0 in case of a serious error.
- VIN Low: This error occurs whenever the voltage in your power supply is low and and is interrupted. If you set recovery thresholds in the Advanced Settings tab, this amazing error will prevent over-draining your battery.
- VIN High: This error occurs when the power supply voltage is too high. You can set the threshold voltage in the Advanced Settings tab.
- Motor Driver Error: This error occurs whenever the motor driver memory chip reports an unacceptable undervoltage or overtemperature condition (shortening the error series).
- Overheating: This error always occurs when the measured value of the temperature sensor is often too high. You can view the temperature measurements in the Conditions field on the Status tab. The behavior of this error, in addition, the threshold temperatures can be configured in the Advanced tab.
- The ERR line is above average: this error occurs when there are no other errors, but the power supply to the ERR line is expensive (2.3-5V). This fault allows your organization to tie together wires connected to two separate motor controllers and disconnect them if one andthey will fail. This error can be disabled again in the Advanced Settings tab.
- Serial Errors: Serial errors are always logged if there are problems with the serial communication, especially on the RX / TX lines or for the USB virtual COM port. If the input mode is serial / USB, the serial port error will simply stop the motor until every valid serial command is received, the resume button is pressed, and the native USB speed and / or possibly commands are set. Bootstrap completes the transfer. If you are using sequential mode and have disabled the unsafe start mode, you will need to issue a “Exit Safe Start” command followed by a “Set Speed” command to correct the error and restart the entire motor. If you are indeed using the series and do not have a safe start, the engine will start running as soon as a large Set Speed command is received. The following types of consecutive errors are logged:
- Frame: there will be an error if desi occurssync or excessive noise will be detected in the RX series.
- Noise: This error occurs when noise is detected on the receive line. Overrun:
- rx This error occurs even if the buffer to hold the bytes sent on the RX line is normal and data has been lost, which is an excellent result. This should not happen during normal operation.
- Format: This error occurs when the bytes received in Serial Direct Receive or Virtual COM Port do not conform to the protocol mentioned in this tutorial. If your company gets this error, take a close look at the bytes you submitted and measure the examples provided. This
- crc: Processing occurs if you have enabled cyclic redundancy check (CRC) for sequential commands, but the CRC byte found is invalid. CRC prevents the motor controller from accidentally processing unwanted actions when receiving commands from a noisy serial website. If you get an error, check your CRC algorithm and check the quality of a good serial signal on the RX pin.
