Webpage Settings

The values displayed in the various tabs are refreshed at the rate defined in the "Data Update Time" select box.
The Data Update Time can be set to 250 ms, 500 ms, 1 second, 2 seconds, or 5 seconds.
■

Email Settings

The "Email Server IP Address" text box must contain the IP address of the email server. The subnet address is
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.
To save the entered information into the option, click "Save Email Settings".

Drive-Side Error Codes

Drive-side error codes appear on the drive keypad. This section lists causes of the errors and possible corrective
actions. Refer to the drive Technical Manual for additional error codes that may appear on the drive keypad.

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.
If communication stops while the drive is running, use these questions as a guide to help remove the fault:
• Is the communication line properly connected to the option? Is it loose?
• Is the option properly installed?
• Is the host controller program working? Is the controller/host controller CPU stopped?
• Did a momentary power loss interrupt communications?
Code Name
bUS Option Communication Error
EF0 Option Card External Fault
oFA00 Option Not Compatible with Port
40
Causes
The drive did not receive a signal from the
controller.
The communications cable wiring is incorrect.
An existing short circuit or communications
disconnection
A data error occurred due to electric interference
Option is damaged
Connection Time-out
Duplicate IP Address found on network
The option received an external fault from the
controller.
A programming error occurred on the controller
side.
The option connected to connector CN5-A is not
compatible.
Invalid DIP switch S1 setting.
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.
• Decrease the effects of electrical interference from the host
controller.
If there are no problems with the wiring and the error continues to
occur, replace the option.
Check if the CPU of the controller is not stopped.
Change to a different IP address. If F7-13 = 0 [Address Mode at
Startup = Static], change parameters F7-01 to F7-04 [IP Address
1 to 4].
1. Find the device that caused the external fault and remove the
cause.
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.
Set the option DIP switch S1 as shown in page 11. Monitor, U4-
75 [Communication OPT Protocol] will display the DIP switch
S1 setting.
