‹ Explicit Message Communications Errors
When there is a problem with a request message sent from the master in explicit communications, the drive will return a
response message with a service code of “94” and an error code from
Table 20 as the data.
Table 20 Explicit Message Error Codes, Causes, and Possible Solutions
Digital Operator Display Fault Name
to oFA30 to oFA43
Option Fault (CN5-A)
Communication ID error.
Cause Possible Solution
Option hardware fault Replace the option. Contact Yaskawa for assistance.
Digital Operator Display Fault Name
oFb00
Non-Compatible Option connected to drive port CN5-B
Non-compatible option is connected.
Cause Possible Solution
Non-compatible option connected to drive port
CN5-B Use only compatible options. Connect the SI-N3 to CN5-A. For other option connections refer
to the Installation Manual for those options.
Digital Operator Display Fault Name
oFb02
Option Fault (CN5-B)
Two of the same option are connected simultaneously.
Cause Possible Solution
Options AI-A3 or D1-A3 connected to the CN5-B
port while an option was connected to CN5-A Only one of these options, AI-A3, DI-A3 or SI- †† option can be connected to the drive at the
same time. The SI-N3 must be connected to CN5-A.
Digital Operator Display Fault Name
oFc00
Non-Compatible Option connected to drive port CN5-C
Non-compatible option is connected.
Cause Possible Solution
Non-compatible option connected to port CN5-C
Use only compatible options. Connect the SI-N3 to CN5-A. For other option connections refer
to the Installation Manual for those options.
Digital Operator Display Fault Name
oFc02
Option Fault (CN5-C)
Two of the same options are connected simultaneously.
Cause Possible Solution
Options AI-A3 or D1-A3 connected to the CN5-C
port while an option was connected to CN5-A Only one of these options, AI-A3, DI-A3 or SI- †† option can be connected to the drive at the
same time. The SI-N3 must be connected to CN5-A.
Digital Operator Display Minor Fault Name
CALL
Serial Communication Transmission Error
Communication has not yet been established.
Cause Possible Solution
Minor Fault
(H2- = 10)
Communication wiring or terminal resistor
connection is faulty. There is a short circuit, or an
option component is not connected properly
Check for wiring errors and correct the wiring.
Remove any ground shorts and reconnect loose wires.
Yes
Master-side programming error Check communications at start-up and correct programming errors.
Damaged communication circuitry
Perform a self-diagnostics check and replace the drive if the fault continues
to occur.
Error Code Description Cause Possible Solution
08FF Service not supported The service code is incorrect. Correct the service code.
09FF Invalid attribute value The attribute is incorrect. Correct the attribute.
0CFF Object state conflict
Attempted to change a drive constant that
cannot be changed while the drive is running.
Stop the drive.
0EFF Attribute not settable Attempted to change a read-only attribute. Correct the service code or attribute setting.
13FF Not enough data The data size is incorrect. Correct the data size.
14FF Attribute not supported
Attempted to execute a service that is not
defined for the attribute.
Correct the service code or attribute setting.
