2 Product Overview

2 Product Overview

◆ About This Product

The option provides a communications connection between the drive and an ODVA
EtherNet/IP network. The option connects the drive to an EtherNet/IP network and
facilitates the exchange of data.

This manual explains the handling, installation and specifications of this product.

EtherNet/IP is a communications link to connect industrial devices (such as smart motor
controllers, operator interfaces, and variable frequency drives) as well as control devices
(such as programmable controllers and computers) to a network. EtherNet/IP is a simple,
networking solution that reduces the cost and time to wire and install factory automation
devices, while providing interchangeability of like components from multiple vendors.

EtherNet/IP is an open device network standard.

By installing the option to a drive, it is possible to do the following from an EtherNet/IP
master device:

• drive operation

• drive operation status monitoring

• changing parameter settings.

◆ Applicable Models

The option can be used with the drive models in Tab le 1 .

■ Installing the Option

Remove the front covers of the drive before installing the option. Refer to the drive Quick
Start Guide for directions on removing the front covers. Cover removal varies depending on
drive size. This option can be inserted only into the CN5-A connector located on the drive
control board.

DANGER! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to
comply could result in death or serious injury. Before installing the option, disconnect all power to the drive
and wait at least the amount of time specified on the drive front cover safety label. After all indicators are off,
measure the DC bus voltage to confirm safe level, and check for unsafe voltages before servicing. The
internal capacitor remains charged after the power supply is turned off.

1. Shut off power to the drive, wait the appropriate amount of time for voltage to

dissipate, then remove the digital operator (D) and front covers (C, F). Refer to the
Quick Start Guide packaged with the drive for directions on removing the front
covers. Cover removal varies depending on drive size.

5. Route the option wiring.

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. Sharp edges along the cut out should be
smoothed down with a file or sand paper 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.

Figure 7

A – Route wires through the openings

provided on the left side of the
front cover.

6. Connect the Ethernet communication cable to the option modular connector (CN1).

To connect the option to a network, insert the RJ45 connector of the Cat 5e patch
cable into the option modular connector (CN1). Ensure the cable end is firmly
connected (see Figure 15).

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).

7. Replace and secure the front cover of the drive (D) and replace the HOA Keypad

Figure 14

(E).

Figure 16 Replace the Front Cover and HOA Keypad

Note: Take proper precautions when wiring the option so that the front covers will easily fit back onto

the drive. Make sure no cables are pinched between the front covers and the drive when
replacing the covers.

8. Set drive parameters in Table 6 for proper option performance.

◆ EDS Files

For easy network implementation of drives equipped with the option, an EDS file can be
obtained from:

U.S.: http://www.yaskawa.com
Europe: http://www.yaskawa.eu.com
Japan: http://www.e-mechatronics.com

Other areas: Contact a Yaskawa representative.

Note: Download the EDS file for SI-EN3 option. The SI-EN3 will not function as a slave in the

network without the appropriate EDS file.

◆ Drive-Side Error Codes

Drive-side error codes appear on the drive digital operator. Causes of the errors and
corrective actions are listed in Table 10. For additional error codes that may appear on the
drive digital operator, refer to the drive Technical Manual.

■ Faults

Both bUS (option communication error) and EF0 (External fault input from the option) can
appear as an alarm or as a fault. When a fault occurs, the digital operator ALM LED remains
lit. 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?

• Is the communication line properly connected to the option? Is it loose?

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

• Did a momentary power loss interrupt communications?

Table 10 Fault Displays, Causes, and Possible Solutions

LED Operator Display Fault Name

Option Communication Error

bUS

Cause Possible Solution

Master controller (PLC) has
stopped communicating

Communication cable is not
connected properly

A data error occurred due to
noise

Option is damaged

Connection Time-out

• After establishing initial communication, the connection was lost

• Only detected when the run command or frequency reference is assigned to the
option (b1-01 = 3 or b1-02 = 3)

• Check that power is supplied to the PLC

• Check that PLC is not in program mode

• Check for faulty wiring

• Correct any wiring problems

• Inspect items that can minimize the effects of electrical noise

• Counteract noise in the control circuit, main circuit, and ground wiring

• If a magnetic contactor is identified as a source of noise, install a surge absorber to

the contactor coil

• Make sure the cable used meets the EtherNet/IP requirements

• Make sure the option ground wire is connected between option FE terminal and the
drive ground terminal connected to earth ground

If there are no problems with the wiring and the error continues to occur, replace the
option.

• The option Requested Packet Interval (RPI) timer timed out

• Make sure that RPI time is set properly

Fault

Declared

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.
