Appendix 2.8 Emergency Stop Alarms (EMG)
483
EMG Emergency stop LINK
Details
A DeviceNet communication error has occurred.
(Any of the network errors L10, L11 and L12 has occurred.)
Remedy
- Clear the network error.
- Setting "0" in "#21113 Add13/bit0 DeviceNet error monitor" disables the DeviceNet communication
error monitoring and clears this alarm.
EMG Emergency stop LAD
Details
The sequence program has an illegal code.
Remedy
- Correct any illegal device Nos. or constants in the sequence program.
EMG Emergency stop CVIN
Details
The "emergency stop" signal for power supply is significant (open) because the external emergency
stop function for power supply is enabled.
Remedy
- Cancel the "emergency stop" signal.
- Check for any broken wires.
- Make sure that NC reset 1 signal, NC rest 2 signal, and reset & rewind signal are all OFF. (All part
systems must be OFF on a multi-part system machine.)
EMG Emergency stop MCT
Details
The status is one of the following:
- The contactor shutoff test is being executed.
- The output OFF check is being executed.
- The "dual signal check start" signal was not ON when "#21161 SftySgnlChkTrg (Dual signal check-
time change)" was set to "1". The output check and contactor welding detection at the power ON
have not been completed.
Remedy
- The emergency stop is reset automatically after the contactor shutoff is confirmed.
- If the contactor shutoff is not confirmed within 5 seconds after the "contactor shutoff test" signal has
been input, the "contactor welding detected" alarm occurs and the emergency stop status remains.
- Make sure that the contactor's auxiliary B contact signal is correctly output to the device that is set in
"#1330 MC_dp1" and "#1331 MC_dp2" (Contactor weld detection device 1 and 2), and then turn the
power ON again.
- The emergency stop is reset automatically after the output OFF check is completed.
- If the contactor shutoff is not confirmed within 5 seconds after the "output OFF check" signal has
been input, the "output OFF check error" alarm occurs. The dual signal module may be broken when
this alarm occurs. Replace the module.
- When "#21161 SftySgnlChkTrg (Dual signal check time change)" is set to "1", turn ON the "dual
signal check start" signal after the power ON.
EMG Emergency stop IPWD
Details
The data backup for power failure might not have been executed successfully at the previous power
failure.
Remedy
- If this message appears frequently, the power supply may be deteriorated. Contact the service
center.
EMG Emergency stop SUIN
Details
The emergency stop input signal (M0) is OFF in the NC/PLC safety circuit.
Remedy
- Check the conditions for turning ON the emergency stop input signal.
- Check for any broken wires.
