Digital Operator Display Minor Fault Name
CALL
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.
Termination resistor setting is incorrect.
Install a termination resistor at both ends of a communication line. Set the internal
termination resistor switch correctly on slave drives. Place DIP switch S1 to the
ON position.
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.
Table 14 Communications Errors and Solutions
Error
Code
(Hex)
Description Cause Possible Solution
08 Service not supported The service code is incorrect. Correct the service code.
09 Invalid attribute value The attribute is incorrect. Correct the attribute.
0C Object state conflict
Attempted to change a drive constant that cannot be
changed while the drive is running.
Stop the drive.
0E Attribute not settable Attempted to change a read-only attribute. Correct the service code or attribute setting.
13 Not enough data The data size is incorrect. Correct the data size.
14 Attribute not supported
Attempted to execute a service not defined for the
attribute.
Correct the service code or attribute setting.
15 Too much data The data size is incorrect. Correct the data size.
16 Object does not exist An unsupported object was specified. Correct the class or instance setting.
1F Vendor-specific error
Attempted to change a drive constant that cannot be
changed while the drive is running.
Attempted to change a drive constant to a value outside
the setting range.
Stop the drive.
Specify a value within the setting range.
