## Step 2: Robot Communication Inspection
Check whether the teach pendant is connected normally and whether there is any alarm signal. Common error situations are as follows:
1. **Not connected error**
Check whether the robot encoder cable is loose and whether the welding machine power supply is turned on.
2. **Emergency stop error**
Check whether the emergency stop switch has been triggered.
3. **Singularity error**
Click “Joint Return to Zero” in the monitoring position, as shown in the figure below.

# IV. Common Problems and Solutions
## 1. Software Connection Failure or Workstation Not Switched Over
**Solution:**
Check whether the teach pendant is in AUTO mode and whether the teach pendant has any alarm. Then connect again and manually switch the workstation, as shown in the figure below.

## 2. Trolley Remote Control Does Not Respond
**Solution:**
The power supply is not turned on, or the remote control is in a low-battery state. The remote-control battery level may appear unstable. Recharge the remote control to solve the problem.
## 3. Unable to Operate the Mobile Robot in the Software
**Solution:**
The tool/workstation switching is abnormal. Check whether either the tool or the workstation has switched to 0. If so, disconnect and reconnect the system to solve the problem, as shown in the figure below.
