Re-set the correct parameter value in the parameter setting of GX Developer.
Why am I getting an overflow error on my Mitsubishi Controller?
An overflow error in your Mitsubishi Controller can occur if: 1) When a linear counter is in use, an add pulse is input beyond the current value of 2147483647. 2) When a linear counter is in use, a subtract pulse is input below the current value of -2147483647. To resolve this, preset the controller to clear the overflow error.
What to do if the input signal is not turned OFF on my Mitsubishi MELSEC Q?
If the input signal on your Mitsubishi Controller isn't turning OFF, it could be due to leakage current from the input switch. To resolve this, connect an appropriate resistor to lower the voltage across the input module terminals below the OFF voltage value. For AC input, it's recommended to use a CR constant with 0.1 to 47 F + 47 to 120 (1/2W). Another cause might be a limit switch with a neon lamp, in which case you can apply the same resistor solution or create an independent display circuit. Finally, leakage current from the wiring cable's line capacity could be the issue. The same resistor fix applies here, but note that leakage current isn't generated when the power supply is located on the input equipment side.
Why is the ERR LED on or flashing on my Mitsubishi Controller?
The ERR LED on your Mitsubishi Controller may be lit or flashing because: - An error is being generated. Confirm the error code and take corrective action described in Section 8.1. - Intelligent function module setting switch 5 is set to "other than 0". Using GX Developer parameter setting, set intelligent function module setting switch 5 to "0".
Why is the RUN LED flashing or off on my Mitsubishi Controller?
The RUN LED might be flashing or turned off if the mode is set to the offset/gain setting mode. Reset switch 4 of the intelligent function module switch setting for GX Developer to the normal mode.
Why is the analog value not within the reference accuracy of the theoretical value on my Mitsubishi MELSEC Q?
If you're using voltage output and observe a small load resistance of the connected external device and a long wiring distance, a voltage drop due to the wiring impedance and load current may be large, and the voltage applied to the external device is low. In this case, the factory default range setting may not satisfy the reference accuracy. Use User range setting and adjust the offset and gain values after wiring.
What should I do if the value set to the G(P).OGLOAD instruction, G(P).OGSTOR instruction or save data classification setting is outside the range on Mitsubishi MELSEC Q Controller?
Set the value within the range.
How do I resolve the issue of a specified digital value being outside the range on my Mitsubishi MELSEC Q Controller?
Set a value that is within the range.
What to do if there is an invalid value in offset/gain setting and the error channel number cannot be identified on Mitsubishi Controller?
Perform the offset/gain setting again for all of the channels that use the user range settings. If the error occurs again, the module may be malfunctioning. Please consult your local Mitsubishi representative, explaining a detailed description of the problem.
How to solve scaling lower limit value equal to or greater than the scaling upper limit value on Mitsubishi Controller?
Set CH scaling upper/lower limit value so that the scaling upper limit value is greater than the scaling lower limit value.
