				Reverts to the first trip indication.

Note 1: Failures that occur during initialization of the CPU on turning on the power or after resetting the inverter are not held by the failure trip holding function, and status monitor indications appear for such the failure.

Note 2: Contents of status indications of *2, *3, *4 and *5 can be selected from 30 kinds of information. Contents of indications that are set up at  to (status monitor #1 to #4 display mode) are displayed.

Unit of current and voltage indications can be changed from % to A (amperage) or V (voltage) and vice versa respectively with (Current/voltage display mode).

8. 4 Indication of alarm, pre-alarm, etc...

When the inverter alarm, pre-alarm, etc. occurred, the contents are displayed. (Some are not displayed.) Listed below ones can be monitored via communication(FC91). Refer to 12.1 for the other alarms.

Bit	Contents of indication	Panel indication
0	Over-current pre-alarm	
1	Inverter overload pre-alarm	
2	Motor overload pre-alarm	
3	Overheat pre-alarm	
4	Over-voltage pre-alarm	
5	Main circuit under-voltage () detected	
6	Poor control power supply () pre-alarm	
7	Low current detected	(no indication)
8	Over-torque detected	(no indication)
9	Braking resistor overload () pre-alarm	(no indication)
10	Cumulative operation time alarm	(no indication)
11	Abnormal communication alarm #1	
	(caused by scanning)
12	Abnormal communication alarm #2	
	(caused by RS485 logic or message transmission)
