Why is the PW LED on my Mitsubishi Electric Controller red?
If the PW LED on your Mitsubishi Electric Controller is red, ensure that the voltage value and the operating ambient temperature are within the specified performance and general ranges, respectively.
Why IP address setting function of Mitsubishi Electric MELSEC iQ-R does not operate properly?
If the IP address setting function of the Mitsubishi Electric Controller does not operate properly, it may be due to the IP addresses or segments of CH.1 and CH.2 overlapping. Check that IP addresses are not duplicated between CH.1 and CH.2 and that the network address portions are not duplicated between CH.1 and CH.2. Also, the changed channel may be invalid. Enable the channel setting using the Setting/monitoring tools for the C Controller module or GX Works3.
What to do if IP address setting by PLC function does not operate properly in Mitsubishi Electric MELSEC iQ-R?
If the IP address setting by PLC function does not operate properly, it could be due to an invalid IP address, subnet mask, or default gateway setting. Error messages in the event history like "Failed To Change Address...Invalid" indicate this. The available setting range of an IP address is from 0.0.0.1 to 223.255.255.254. The available setting range of a subnet mask is from 192.0.0.0 to 255.255.255.252. When not using the default gateway, set 0.0.0.0. The available setting range of a default gateway is from 0.0.0.1 to 223.255.255.254. Review the settings and correct any invalid values.
How to set primary current of CT within range for Mitsubishi Electric Control Unit?
To resolve the 'Primary current of CT is set out of range' error on your Mitsubishi Electric Control Unit, set the primary current of CT within the range of 0 to 6000 (A). However, this setting cannot set 0 (Any current (EMU-CT5-A)) or 1000 (Any current (EMU2-CT5)) when primary current (Un\G2) is 0.
What to do if the L PW LED does not turn on on a Mitsubishi Electric MELSEC iQ-R Controller?
If the L PW LED on your Mitsubishi Electric Controller doesn't turn on, wire the load power supply, turn on the load power supply, and ensure the voltage value is within the performance specifications.
What to do if the measured current and voltage from my Mitsubishi Electric Control Unit don't match other gauges?
If the current and voltage measured by your Mitsubishi Electric Control Unit do not match other gauges, consider the following: * Verify the phase wire method, primary current, and primary voltage are correct. Check the value in the buffer memory for these settings. If you change the value in the buffer memory, you need to turn the request for operating condition setting into ON. Otherwise, it will not be applied to the measurement. * Ensure the secondary of the current sensor is not short-circuited. If connected to Mitsubishi’s current transformer CW-5S (L), check that the secondary switch is not short-circuited. * Confirm that only dedicated current sensors are connected to the module. Do not use sensors from other companies.
How to fix 'Flash ROM error' on Mitsubishi Electric MELSEC iQ-R?
A 'Flash ROM error' on your Mitsubishi Electric Controller signifies a failure to access the flash ROM of the CPU module. You should execute the firmware update function again.
What to do if I get a 'Firmware data error' on my Mitsubishi Electric MELSEC iQ-R?
If your Mitsubishi Electric Controller displays a 'Firmware data error', it means an error was detected during the firmware update. You should execute the firmware update function again.
What to do when ERR LED is turned on or flashing on Mitsubishi Electric Control Unit?
If the ERR LED is on or flashing on your Mitsubishi Electric Control Unit, it indicates an error. Check the latest error code (Un\G3000) and take corrective action. After that, reset the CPU module and check whether it is turned on. If the ERR LED remains on, the module may have failed.
Why is Mitsubishi Electric MELSEC iQ-R time not setting to the network camera?
If the time of your programmable controller isn't being reflected on the network camera, it may be that the time of the programmable controller is not reflected on the network camera side. Try closing the configuration tool of the network camera and then execute the FB again.
