configured in drive parameters F7-05 through F7-08. The configured email alerts will use the server at this
address when sending emails.
Enter the email server port in the "Email Server Port" text box.
The value in the "From Email Address" text box identifies the origin of the email alerts to the recipient.

Faults

Both bUS [Option Communication Error] and EF0 [Option Card External Fault] can appear as a fault. When a
fault occurs, the keypad ALM LED stays lit. When an alarm occurs, the ALM LED flashes. When an alarm
occurs, the ALM LED flashes.
If communication stops while the drive is running, use the following questions as a guide to help remedy the fault:
• Is the communication line properly connected to the option? Is it loose?
• Did you correctly connect the communication line to the option?
• Is the PLC program working? Is the controller/PLC CPU stopped?
• Did a momentary power loss interrupt communications?

lists causes of the errors and possible
Possible Solutions
• Check for wiring errors.
• Correct the wiring.
Check disconnected cables and short circuits and repair as needed
• Prevent noise in the control circuit, main circuit, and ground
wiring.
• If you identify a magnetic contactor as a source of noise,
install a surge absorber to the contactor coil.
• Use only recommended cables or other shielded line. Ground
the shield on the controller side or the drive input power side.
• Separate all communication wiring from drive power lines.
Install an EMC noise filter to the drive power supply input.
• Counteract noise in the master controller (PLC).
If there are no problems with the wiring and the error continues to
occur, replace the option.
• The option Requested Packet Interval (RPI) timer timed out
• Make sure that RPI time is set properly
Check if the option shares Station Address with at least one other
node. Check the setting values of F6-20 [MECHATROLINK
Station Address].
1. Find the device that caused the external fault and remove the
caus.
2. Clear the external fault input from the controller.
Examine the operation of the controller program.
Connect the option to the correct connector.
• Use connector CN5-A when you connect the option.
To use other options, refer to those option manuals.
1. De-energize the drive.
2. Connect the option to the correct option port.
1. De-energize the drive.
