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.

Factory setting: 0
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.
