When an industrial robot is in motion, an abnormal power outage can result in undervoltage of the batteries in the control cabinet or an interruption in the power supply to the 

NVRAM (Non-Volatile Random Access Memory.) The NVRAM is typically used to store critical information such as the robot's zero position, register data, and system time. Once 

this information is lost, the robot experiences a loss of zero point. To recover the zero point, the following steps are typically required:

1.Calibrate Zero: Use the robot's calibration function to reset the robot's zero position.

2.Data Recovery: If a program backup was previously performed, the backup file can be used to recover the data in the registers.

3.Time Calibration: Recalibrate the controller's time to ensure proper system timing.

Ensure that the manufacturer's instructions are followed during operation to avoid further damage or incorrect operation. If more detailed instructions are required, it is 

recommended to refer to the relevant robot operation manual or contact Agilebot technical support.

Indicates a battery under-voltage alarm, please check it according to the following steps:

1. Use a multimeter DC voltage gear to measure whether the robot body encoder battery has voltage (about DC 3V or so);

2. If the voltage is low, replace the battery pack of the robot body encoder and re-calibrate the zero point;

3. If the voltage is normal, check whether the encoder connecting wire is broken;

1. Check if the teach pendant mode is switched to A;

2. Check whether the status of robot system signals UI1, UI2 and UI5 is ON.

3. Check whether the program start mode is “set as the main program number start simple mode” or “main program number start”;

4. Check whether the startup program number setting is consistent with the status of external startup program number input signals UI8-UI13 (binary number);

5. Check whether the start signal is input and whether the start timing is correct.

1. Check whether the teach pendant mode is switched to M or L gear;

2. Check whether the status of robot system signals UI1, UI2 and UI5 is ON;.

3. Check whether the Deadman switch on the back of the  teach pendant is in the middle gear, and press the RESET button.

1. Check the name plate of the robot control cabinet and confirm the input and output signal type of the control cabinet (NPN or PNP);

2. Check whether the solenoid valve and relay control voltage is consistent with the control cabinet output voltage;

3. Check the manual according to the control cabinet input and output signal type, confirm the signal common port (COM) wiring is correct, confirm the signal wiring pin port is correct;

4. Check whether the IO signal number and mapping start port number are correct.

1. Check the nameplate of the robot control cabinet and confirm the input and output signal type of the control cabinet (NPN or PNP);

2. Check whether the sensor output type is consistent with the control cabinet type;

3. Check the manual to confirm the signal common port (COM) wiring is correct according to the control cabinet input/output signal type, and confirm the signal wiring pin port is correct;

4. Check whether the IO signal number and mapping start port number are correct.

1. Check whether the robot IP address and the third party settings are in the same network segment or whether there is any conflict in the IP address;

2. Click Menu-Communication-Bus Configuration-Configuration on the robot teach pendant to check whether the function is active or not, and the correct status should be active;

3. Click Menu-Communication-IO Mapping on the Teach Pendant, and enter the IO Mapping configuration page to confirm whether the module number is selected as “ModbusServer/TCP/128/256in:256out”;

4. Check whether the IO signal number and mapping start port number are correct.

1. Check whether  the PR bit pose registers used in the program have  been deleted or changed in ID number;

2. Check whether the DI, DO,GI and GO signals used in the program aremapped;

3. Check whether the SR, R, etc. registers used in the program are present.
