bUS Fault Tolerance
■
bUS Fault Auto-Restart
Parameter
F6-14 [bUS Fault Auto Reset Select]
will appear when the option is installed.
Setting
F6-14 = 0 [Disabled]
or
F6-01 = 3 or greater (Alarm only)
will not affect standard default drive behavior.
Setting
F6-14 = 1 [Enabled]
AND
F6-01 ≠ 3 [Fault]
will cause the following operation:
1. The bUS fault occurs after the
F7-16 [Timeout Value]
delay and the Run command is removed from the drive.
2. Then the option throws a
bUS
fault to the drive.
3. When the condition is removed, the option commands a fault reset and returns control of the drive to the
EtherNet/IP network.
Note:
The option will only read parameter
F6-01
and
F6-14
from the drive during power-up.
■
bUS Fault Delay
Parameter
F7-16 [Timeout Value]
will appear when the option is installed. The setting value of
F7-16
is the length
of time that the option will delay sending the
bUS
fault to the drive. The status LEDs on the option are not
affected by the delay time set in
F7-16
; the LEDs will indicate the
bUS
condition immediately.
Note:
The option will only read parameter
F7-16
from the drive during power-up.
