bUS Fault Auto-Restart
Parameter
F6-14 [BUS Error Auto Reset]
will appear when the option is installed.
Setting
F6-14 = 0 [Disabled]
or
F6-01 = 3, 4, 5 [Alarm Only, Alarm (Run at d1-04), Alarm - Ramp Stop]
will not
affect standard default drive behavior.
Setting
F6-14 = 1 [Enabled]
AND
F6-01 = 0, 1, 2 [Ramp to Stop, Coast to Stop, Fast Stop (Use C1-09)]
will
cause the following operation:
1. Then the option throws a
bUS
fault to the drive.
2. When the condition is removed, the option commands a fault reset and returns control of the drive to the
Modbus TCP/IP network.

The option card has a hardware error. Cycle the power on the

Two drive monitor parameters,
U6-98 [First Fault]
and
U6-99 [Current Fault]
assist the user in network
troubleshooting.
•
U6-98
displays the first declared fault since the last power cycle.
U6-98
is only cleared upon drive power-up.
•
U6-99
displays the present option status.
U6-99
is cleared upon a network-issued fault reset and upon power-up.
If another fault occurs while the original fault is still active, parameter
U6-98
retains the original fault value and
U6-99
stores the new fault status value.
