Alarm name Causes/countermeasures
6D
(86D)
Power supply unit
communication error
Cause: It is a communication error between the gateway unit and IAI
24V DC power supply unit (model code: PSA-24).
1) Communication cable disconnection or connector contact
failure
2) Incorrect setting of number of power supply units
connected
3) The address setting on the rotary switch on the power
supply unit is inappropriate.
4) Influence from noise
Countermeasure: 1) Check the cable and connector.
2) Confirm with gateway setting tool.
3) Confirm whether address is duplicated.
4) Take measures against noise, such as revising
cable arrangements.
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.
A0
(8A0)
Excessive control power
supply voltage
Cause: Control power supply voltage exceeded the overvoltage
judgment value (120% of 24 VDC = 28.8 V).
1) 24 VDC power supply voltage is high
2) Malfunction of parts inside the gateway unit
3) During acceleration/deceleration or servo ON, etc,,
consumption current rises momentarily. When remote
sensing function is used with power of barely sufficient
current capacity, overvoltage may occur in response to the
current change.
Countermeasure: 1) 2) Check power supply voltage.
3) Consider using a power supply with sufficient
current capacity, or avoid using the remote
sensing function.
If voltage value is normal, contact IAI.
A1
(8A1)
Control power supply
voltage drop
Cause: Control power supply voltage went below the voltage drop
judgment value (70% of 24 VDC = 16.8 V).
1) 24 VDC power supply voltage is low
2) Malfunction of parts inside the gateway unit
Countermeasure: Check power supply voltage.
If voltage value is normal, contact IAI.
