Serial Communication Transmission Error
Communication has not yet been established.
Cause Possible Solutions
Minor Fault
(H2-oo = 10)
Communications wiring is faulty, there is a
short circuit, the wiring is incorrect, or the
connections are poor.
• Check for wiring errors.
• Correct the wiring.
• Check for disconnected cables and short circuits. Repair as needed.
YES Programming error on the master side. Check communications at start-up and correct programming errors.
Communications circuitry is damaged.
• 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.
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 Modbus TCP/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.
u Option Error Codes
n Option Fault Monitors U6-98 and U6-99
