ground terminal and installation hole on the option (B) using the last remaining
provided screw (H) and tighten both screws to 0.5 to 0.6 N•m (4.4 to 5.3 in lbs).
Figure 6 Connect the Ground Wire
Note:There are two screw holes on the drive for use as ground terminals. When connecting three
options, two ground wires will need to share the same drive ground terminal.
Route the option wiring.
5.
Depending on the drive model, some drives may require routing the wiring through
the side of the front cover to the outside to provide adequate space for the wiring.
Refer to the Peripheral Devices & Options section of the drive Quick Start Guide or
Technical Manual for more information on wire routing of specific models.
Route the wiring through the side of the front cover to the outside. In these cases,
using diagonal cutting pliers, cut out the perforated openings on the left side of the
drive front cover as shown in Figure 7-A. Use a file or sandpaper to make the sharp
edges along the cutout smoother to prevent any damage to the wires. Route the wiring
inside the enclosure as shown in Figure 7-B for drives that do not require routing
through the front cover.
Note:Separate communication cables from main circuit wiring and other electrical lines.
<1> The drive will not meet NEMA Type 1 requirements if wiring is exposed outside the enclosure.

port 1.
To connect the option to a network, firmly connect RJ45 8-pin shielded twisted pair
Cat5e cable(s) into the modular connector ports (see Figure 7).
IGMP Snooping
Switches implementing IGMP Snooping are strongly recommended. When IGMP
Snooping is used, devices will only receive the multicast packets in which they are
interested.
Communication Cable Specifications
Only use cable recommended for EtherNet/Industrial Protocol (EtherNet/IP™). Using
a cable not specifically recommended may cause the option or drive to malfunction.
Refer to the ODVA website for more information on network cabling (http://
www.odva.org).
The dual RJ45 network ports on the option board act as a switch to allow for flexibility
in cabling topology. For example, a traditional star network topology may be employed
by using a single port on the option board. Alternatively, a daisy-chained approach
may be employed by using both RJ45 ports. The daisy-chained approach reduces
the requirements of central switch ports. A ring topology is also possible.
The following parameters are used to set up the drive for operation with the option. Parameter
setting instructions can be found in the drive manual.
Confirm proper setting of the parameters in Table 5 before starting network communications.
After changing parameter settings, cycle power to the drive for the new settings to take effect.

Serial Communication Transmission Error
Communication has not yet been established.
• Check for wiring errors.
• Correct the wiring.
• Check for disconnected cables and short circuits. Repair as
needed.
Check communications at start-up and correct programming
errors.
• Perform a self-diagnostics check.
• If the problem continues, replace the control board or the
entire drive. Contact Yaskawa for instructions on replacing
the control board.
Install a termination resistor at both ends of a communication
line. Set the internal termination resistor switch correctly on
slave drives. Place DIP switch S1 to the ON position.

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: The
bUS fault occurs after the F7-16 delay and the Run command is removed from the drive. Then
the option throws a bUS fault to the drive. 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, Communications Loss Detection Time Delay, 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.
When there is a problem with a request message sent from the master in explicit
communications, the drive will return one of the following error codes.

Two drive monitor parameters, U6-98 and U6-99 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.
