When the FR-CS80 inverter detects an abnormality, it will display an error message or alarm in the operation panel according to the abnormal content, or maintain the function action and block the output of the inverter. When maintaining a function operation, please deal with the cause of its operation before resetting the inverter, and then start working. Restarting without proper treatment may result in problems or damage to the drive.
[Please pay attention to the following points when maintaining the function operation]
1. Abnormal output signal During the maintenance function, if the electromagnetic contactor (MC) set on the input side of the inverter is disconnected, the control power supply of the inverter will be lost, and the abnormal output cannot be maintained.
2. Abnormal appearance
After the maintenance function is performed, abnormal content will be displayed in the operation panel.
3. Re-launch method
After the maintenance function is activated, the inverter will continue to output the abort state. As long as the inverter is required to reset when it is restarted.
【Types of abnormal manifestations of inverters】
1. Fault information
Information is displayed for operating or setting errors on the control panel or parameter unit. The inverter does not block the output.
2. Call the police
Even if an alarm is displayed in the operation panel, the inverter will not block the output, but if it is not adopted, it may cause serious problems.
3. Minor problems
The inverter does not block the output. It can output a light bug (LF) signal after parameter setting.
4. Heavy problems
After the maintenance function is operated, the output of the inverter is intercepted, and the abnormal (ALM) signal is output.
[Recognition and eradication of the pre-police history]
It is possible to store the alarm display of abnormal content when the last 8 maintenance functions are performed in the operation panel. (Pre-alarm history)
1. Methods for acknowledging the history of the police
*1 When an overcurrent trips due to a short-term overcurrent, the current supervision value stored in the alarm history may be lower than the actual current value. *2 The cumulative energizing time and actual operating time are accumulated from 0 to 65,535 hours, and then from 0 again after clearing zero.
Second, the eradication process of the pre-alarm history
1. The screen when the power is turned on
The supervisor manifests.
2. Parameter setting form
Press the SET button to switch to the parameter setting format.
3. Parameter selection
. Press the SET button twice to display the next parameter.

Ground leakage current of Mitsubishi inverter and countermeasures thereof
There is electrostatic capacitance between the input and output wiring of Mitsubishi inverters and other wires, between the ground and the motor, and there is a leakage current flow. The leakage current value is affected by factors such as electrostatic capacitance and carrier frequency, and the leakage current is high when the carrier frequency of the inverter is set high and the leakage current is operated under low noise conditions.
