Fault Types

The drive has four types of faults. These types differ from each other on the basis of the subsequent behavior of the drive. See Table 5-8.

Fault Type Symbol

Meaning

A (Alarm)	This type of fault is a sign of an unusual operating condition. It does not cause
	the drive to stop, nor does it require any special actions. The “A fault” remains
	in the display for about 30 seconds.
F (Fault)	An “F fault” makes the drive stop. Actions need to be taken to restart the drive.
AR (Fault Autoreset)	If an “AR fault” occurs the drive will stop immediately. The fault is reset
	automatically and the drive tries to restart the motor. Finally, if the restart is not
	successful, a fault trip (FT, see below) occurs.
FT (Fault Trip)	If the drive is unable to restart the motor after an AR fault an FT fault occurs.
	The “FT fault” has basically the same effect as the F fault: the drive is stopped.

Note: Fault Codes are listed in Appendix A.

Fault Time Data Record

When a fault occurs, the information described in Figure 5-8is displayed. By pressing Menu Button Right, you will enter the Fault time data record menu indicated by T.1➔T.#. In this menu, some selected important data valid at the time of the fault are recorded. This feature will help the user or the service person in determining the cause of the fault.
