Minor Faults and Alarms

Cause
Communications wiring is faulty,
there is a short circuit, the wiring
is incorrect, or the connections are
poor.
Programming error on the master
side.
Communications circuitry is
damaged.
n bUS Fault Tolerance
bUS Fault Auto-Restart
Parameter F6-14, bUS Fault Auto Reset Select, will appear when the option is installed.
Setting F6-14 = 0 (Disabled) or F6-01 = 3 or greater (Alarm only) will not affect standard
default drive behavior.
Setting F6-14 = 1 (Enabled) AND F6-01 ≠ 3 (Fault) will cause the following operation: The
bUS fault occurs after the F7-16 delay and the Run command is removed from the drive. Then
the option throws a bUS fault to the drive. When the condition is removed, the option
commands a fault reset and returns control of the drive to the EtherNet/IP network.
Note: The option will only read parameter F6-01 and F6-14 from the drive during power-up.
bUS Fault Delay
Parameter F7-16, Communications Loss Detection Time Delay, will appear when the option
is installed.
The setting value of F7-16 is the length of time that the option will delay sending the bUS
fault to the drive.
The status LEDs on the option are not affected by the delay time set in F7-16; the LEDs will
indicate the bUS condition immediately.
Note: The option will only read parameter F7-16 from the drive during power-up.
n Explicit Message Communications Errors
When there is a problem with a request message sent from the master in explicit
communications, the drive will return one of the following error codes.

Communication has not yet been established.
Possible Solutions
• Check for wiring errors.
• Correct the wiring.
• Check for disconnected cables and short circuits. Repair as
needed.
Check communications at start-up and correct programming
errors.
• Perform a self-diagnostics check.
• If the problem continues, replace the control board or the
entire drive. Contact Yaskawa for instructions on replacing
the control board.
