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.

openings provided on the
left side of the front

<1>

cover.

Figure 7 Wire Routing Examples

<1> The drive will not meet NEMA Type 1 requirements if wiring is exposed outside the enclosure.

Connect the communication cable to the option modular connector (CN1) port 1.

6.

B – Use the open space

provided inside the drive

to route option wiring.

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).

Communication Cable Specifications

Only use cable recommended for Modbus TCP/IP. Using a cable not specifically
recommended may cause the option or drive to malfunction.

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. When
implementing a ring topology, Rapid Spanning Tree Protocol (RSTP) must be enabled
to function correctly.

Modbus TCP/IP Overview

The Modbus TCP/IP protocol is essentially the Modbus protocol over an Modbus TCP/IP
network. A master controller (typically a PLC) sends commands to slave devices, which then
perform the specified functions and send a response to the master. The drive using the option
has slave functionality.

Many of the registers required for control have been specially mapped to provide higher speed
access to increase network performance. Use these registers for the best response times.

All of the drive command registers have been mapped to this high speed access area (Modbus
TCP/IP registers 01H to 01FH). In addition, the monitors shown in Table 7 are mapped for
high speed access.

Enter Command Types

The drive supports two types of Enter commands as shown in Table 8. An Enter command is
enabled by writing 0 to register number 0900H or 0910H. These registers can be written to
only. An error will occur if the user attempts to read from these registers.

EEPROM too often. The Enter command registers are write-only. Consequently, if these registers
are read, then the register address will be invalid (Error code: 02H). An Enter command is not required
if reference or broadcast data are sent to the drive.

2. Parameter data cannot be written to EEPROM during undervoltage, even using 0900H.

3. If undervoltage occurs when a making several parameter changes issued with a single ENTER

command, the writing process may be aborted before all of the new changes have been written.
Because all of the data has not yet been written, the EEPROM data error “CPF06” will be displayed
the next time power to the drive is cycled. To prevent this problem, wait approximately 5 seconds
after issuing the ENTER command before shutting off drive power.

When replacing earlier Yaskawa drive models with a V1000 and keeping the MEMOBUS/
Modbus communications settings, parameter H5-11 needs to be set in accordance with how
the Enter command functions in the older drive. H5-11 determines if an Enter command is
needed to activate parameter changes in the drive.

• Set parameter H5-11 to 0 when upgrading from a G7 or F7 series drive to V1000-Series
drive.

• Set parameter H5-11 to 1 when upgrading from a V7 series drive to V1000-Series drive.

When an alarm occurs, the ALM LED flashes.

If communication stops while the drive is running, use the following questions as a guide to
help remedy the fault:

• Is the option properly installed?

• Are the communication lines properly connected to the option? Are the wires loose?

• Is the controller program working? Has the controller/PLC CPU stopped?

• Did a momentary power loss interrupt communications?

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.

programmed into the option. Return for
reprogramming.

Option card hardware has stopped
functioning. Cycle power to the drive.

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.
