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, 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 ≤ 2 [Fast Stop (Use C1-09)] will cause the following operation:
1. The bUS fault occurs after the time set in F7-57 [BACnet/IP bUS Timeout Value].
2. When the condition is removed, the option commands a fault reset and returns control of the drive to the
BACnet/IP network.
Note:
A change of F6-14 does not require a power cycle or parameter reload.
When F7-57 > 0 [BACnet/IP BUS Timeout Value > 0 seconds], the BACnet/IP controller must periodically send a
Frequency Reference Command (AV2), or a Run/Stop command (AV1, BV1, BV2, BV58, BV59 and AV43 to
AV51 where supported). If the BACnet/IP controller does not send a command for the length of time set in F7-57
and the drive is running, the drive will detect a bUS [Option Communication Error] fault.
To disable BACnet/IP Timeout detection, set F7-57 = 0. When this parameter is set to 0, a periodic command
from the BACnet/IP controller is not necessary.

Causes
BACnet/IP is not installed on the JOHB-SMP3
card.
Drive software is not compatible with BACnet/IP
on the JOHB-SMP3 card.
The option connected to the option port CN5-A was
changed during run.
A fault occurred in the option.
A fault occurred in the option.
The option connected to connector CN5-B is not
compatible.
An option of the same type is already installed in
the option port CN5-A, CN5-B, or CN5-C.
The option connected to connector CN5-C is not
compatible.
An option of the same type is already installed in
the option port CN5-A, CN5-B, or CN5-C.
Invalid DIP switch S1 setting.
BACnet/IP is not installed on the JOHB-SMP3
card.
Causes
Port 1 is at a link speed different from Port 2 (100
Mbps and 10 Mbps). Data will not be passed
between the two ports in this condition.
9 Troubleshooting
Possible Solutions
Upgrade the software in the JOHB-SMP3. For details, consult
your local Yaskawa representative.
Upgrade the software in the drive. For details, consult your local
Yaskawa representative.
1. De-energize the drive.
2. Connect the option to the correct option port.
1. De-energize the drive.
2. Make sure that the option is correctly connected to the
connector.
3. If the problem continues, replace the option.

Connect the option to the correct connector.
• Use connector CN5-A when you connect the option.
To use other options, refer to those option manuals.

Set the option DIP switch S1 as shown in page 11. Monitor, U4-
75 [Communication OPT Protocol] will display the DIP switch
S1 setting.

Possible Solutions
• AUTO NEGOTIATE: When F7-14 = 1 [Duplex Mode
Selection = Auto/Auto (Auto Negotiation/Auto Negotiation)],
make sure that the devices connected to the two ports of the
JOHB-SMP3 have the same speed (both at 10 Mbps or both at
100 Mbps).
• FORCED DUPLEX SETTING: When F7-14 ≠1 [Duplex
Mode Selection ≠ Auto/Auto (Auto Negotiation/Auto
Negotiation)], set the two connected ports to the same speed
using F7-15. You cannot set F7-15 to 101 or 102.
