Minor Fault
(H2-
= 10)
Communication wiring is faulty, there is a short
circuit, or improper connection.
Check for wiring errors:
• Correct the wiring.
• Remove ground shorts and reconnect loose wires.
YES
Programming error on the master side.
Check communications at start-up and correct programming errors.

Cause
Possible Solution
Minor Fault
(H2-
= 10)
Communication wiring is faulty, there is a short
circuit, or something is not connected properly.
Check for wiring errors.
• Correct the wiring.
• Remove and ground shorts and reconnect loose wires.
YES
EEPROM checksum error
If these errors occur, the object dictionary will be reset to its default
values.
• After the object dictionary has been changed and object dictionary
contents are then changed, execute a Store Parameter command
(Index = 1010 (Hex)).
• If the object dictionary has not been changed, execute a Restore
Parameter command (Index = 1011 (Hex)).
Option Card
<1> If two PG option cards are connected, use both CN5-B and CN5-C. If only one PG option card is connected to the drive, use the CN5-C
connector.
<2> These option cards are not available for the application with Motor 2 Selection.
<3> These option cards are not available with models CIMR-A
4A0930 and 4A1200.
<4> When AI-A3 and DI-A3 are to be used as monitors, the card can be connected to any of CN5-A, CN5-B or CN5-C. The input status of
AI-A3 can then be viewed using U1-21, U1-22, and U1-23, and the input status of DI-A3 can then be viewed using U1-17.
