Alarms, warnings and communication errors

−38−

5.3 Communication errors

Up to 10 communication errors are saved in the RAM in order of the latest to the oldest. They can be checked via

RS-485 communication.

Cause

Remedial action

84h RS-485 communication error

One of the following errors was detected.

· Framing error

· BCC error

•

Check the connection between

the driver and programmable

controller.

•

Check the setting of RS-485

communication.

88h Command not yet defined

The command requested by the master

could not be executed because of being

undefined.

•

Check the setting value for the

command.

•

Check the flame configuration.

89h User I/F communication in

progress

The command requested by the master

could not be executed since the

MEXE02

OPX-2A

was communicating with the

driver.

Wait until the processing for the

MEXE02

OPX-2A

will be

completed.

8Ah Non-volatile memory

processing in progress

The command could not be executed

because the driver was under the non-

volatile memory processing.

· Internal processing was in progress.

(S-BSY is ON.)

· An EEPROM error alarm was present.

•

Wait until the internal processing

will be completed.

•

When the EEPROM error was

generated, initialize all parameters

using any of the

MEXE02

OPX-2A

or RS-485 communication.

8Ch Outside setting range

The setting data requested by the master

could not be executed due to out of

range.

Check the setting data.

8Dh Command execute disable

When the command is unable to execute,

it was tried to execute.

Check the driver status.

Communication error history

Up to 10 communication errors are saved in the RAM in order of the latest to oldest. The communication error

history saved in the RAM can be read and cleared when any of the following items is performed.

•

Read the communication error history with the monitor command.

•

Clear the communication error history with the maintenance command.

•

Read and clear the communication error history using the

MEXE02

Note

The communication error history is cleared when the driver power is turned off.
