7.2 EC Gateway Unit Alarm Causes and Countermeasures
7.2.1 Causes and countermeasures of individual alarms
The alarm codes will be read out in gateway status signal 0 ALMC1 ~ 128 (b0 ~ b7).
For details, refer to "5.2 Address Configuration (page 5.2)".
(Note) Alarm codes displayed on the gateway parameter configuration tool have "8" added at
the beginning of the alarm codes listed below.
(Example) If the alarm code is 43, it will be displayed as 843.
Alarm
code
Alarm name Causes/countermeasures
50
(850)
Field network
communication error
(ERR-C)
Cause: Field network link error. If a latch is set with the gateway
parameter configuration tool while this error is generated,
actuator operation will stop in error status and commands will
be ignored until the cancel signal is received.
Countermeasure: Check field network settings (node address,
communication speed, etc.), wiring, etc.
61
(861)
Dependent axis internal
communication error
(transmission)
Cause: RCON internal communication error. Communication failure
with driver unit connecting actuator axes.
Countermeasure: Reboot the power. If it occurs again, contact IAI.
62
(862)
Dependent axis internal
communication error
(reception)
Cause: RCON internal communication error. Communication failure
with driver unit connecting actuator axes.
Countermeasure: Reboot the power. If it occurs again, contact IAI.
80
(880)
GW parameter error
Cause: Gateway parameters are abnormal.
Countermeasure: Check connected axes, operation mode, etc. with
gateway parameter configuration tool.
81
(881)
Parameter check sum
error
Cause: RCON internal memory data may be damaged.
Countermeasure: Reset with the gateway parameter configuration
tool, or if backup is available, write in the backup
data.
9B
(89B)
Field network
module error
Cause: Field network module failure is possible.
Countermeasure: Contact IAI if this reoccurs even after turning ON
the power again.
9C
(89C)
Field network module
undetected
Cause: Communication circuit board for field network could not be
confirmed.
1) Communication circuit board is not inserted.
2) Malfunction of communication circuit board
Countermeasure: Reboot the power. If it occurs again, contact IAI.
9D
(89D)
Field network module
initialization timeout
Cause: Initialization of field network module did not complete after a
given period of time.
Countermeasure: Reboot the power. If it occurs again, contact IAI.
