Troubleshooting by Symptom

This section describes troubleshooting when a data link cannot be performed with the target station regardless of no error
occurring in the Motion module.
If an error has occurred in the Motion module, identify the error cause using the engineering tool. ( Page 146 Checking
the Network Status)
• Cyclic transmission failed (Page 158 Cyclic transmission failed)
• Transient transmission failed (Page 162 Transient transmission failed)
• Station is disconnected from the network (Page 165 Station is disconnected from the network)
• Station repeats disconnection and return (Page 165 Station repeats disconnection and return)
• Communications are unstable (Page 166 Communications are unstable)
• SLMP communications failed (Page 167 SLMP communications failed)
• Communications with Ethernet devices failed (Page 168 Communications with Ethernet devices failed)

• Safety communications failed (Page 169 Safety communications failed)
• Network map is not displayed correctly (Page 170 Network map is not displayed correctly)
• No error is occurring but motion control cannot be started (Page 170 No error is occurring but motion control cannot be
started)
