10 Troubleshooting
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.

Option Fault Monitors U6-98 and U6-99

The option can declare error/warning conditions via drive monitor parameters on the drive keypad as shown in
Table 10.1.

Setting Error
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.

Communication Error

If there are no errors in your drive, but communication with other devices is not possible, do the corrective steps
in the table below.
Status
LINK/ACT LED does not light.
◆

Self RAM Check

Use these procedures to do a self RAM check for all areas including unused areas.

Status Value
(U6-98/U6-99)
3 The network sent a message to force this node into a fault state.
1300 No physical link to another device. This happens after a link is established and
removed.
1301 PLC connection timeout. This indicates a network problem, for example PLC offline or
switch disconnected.
1303 Factory default MAC Address programmed into the option.
Note:
Return the option to Yaskawa or your nearest sales representative and request the
setting change.
1304 Card does not have an IP address. This happens when the JOHB-SMP3 is set to have
the PLC configure the IP address but it has not been received yet (F7-13 = 1 or 2
[Address Mode at Startup = Set by PLC]).
1305 No station name programmed. Program a name through web page or PLC configuration
program.
Note:
If the DIP switches are changed on the JOHB-SMP3, the station name will
automatically be erased.
1309 The configured IP addresses are incompatible. The IP Address (F7-01 to F7-04) does
not agree with the Subnet Mask (F7-05 to F7-08) and/or the Gateway Address (F7-09
to F7-12)
Adjusting the above parameters or setting the PLC to assign the IP address should clear
this fault.
1310 Failure to read the web interface setting.
Set F7-14 = 1 [Duplex Mode Selection = Auto/Auto (Auto Negotiation/Auto Negotiation)].
