It will record when the fault occurs and force stopping. For the Lv, it will record when it is operation, or it will warn without record.

mode
	Settings	0		By settings of Pr.06-22~06-25
		1		By the binary setting

It is used with the settings 35~38 of Pr.02-11~02-22 (Multi-function Output). The fault output selection 1~4 corresponds to Bit 0~3.

This parameter provides two setting methods for the fault output: setting 0: it is set by the

settings of Pr.06-22~Pr.06-25; setting 1: it is set by the binary setting and please refer to the following example for details.

Example:

Assume that

Pr.02-15 (Multi-function Output 5 (MO3)) is set to 35 Fault output option 1 (Pr.06-22). Pr.02-17 (Multi-function Output 7 (MO5)) is set to 36 Fault output option 2 (Pr.06-23). Pr.02-19 (Multi-function Output 9 (MO7)) is set to 37 Fault output option 3 (Pr.06-24).

Pr.02-21 (Multi-function Output 11 (MO9)) is set to 38 Fault output option 4 (Pr.06-25). Assume that external faults output with the following signal: MO3=1, MO5=1, MO7=0 and MO9=1. The corresponding Bit 3~0 is 1011.

		Bit 3	Bit 2	Bit 1	Bit 0	Fault code
	-		-	-	-	0: No fault
						1: Over-current during acceleration (ocA)
						2: Over-current during deceleration (ocd)
0			0	0	1	3: Over-current during constant speed (ocn)
						4: Ground fault (GFF)
						5: IGBT short-circuit (occ)
						6: Over-curent at stop (ocS)
		0	0	1	0	7: Over-voltage during acceleration (ovA)
						8: Over-voltage during deceleration (ovd)
