1.1 About this Manual

This manual, AKD EtherCAT Communication, describes the installation, setup, range of functions, and soft-

ware protocol for the EtherCAT AKD product series. All AKD EtherCAT drives have built-in EtherCAT func-

tionality; therefore an additional option card is not required.

A digital version of this manual (pdf format) is available on the CD-ROM included with your drive. Manual

updates can be downloaded from the Kollmorgen website.

Related documents for the AKD series include:

lAKD Quick Start (also provided in hard copy). This guide provides instructions for basic drive setup

and connection to a network.

lAKD Installation Manual (also provided in hard copy). This manual provides instructions for installation

and drive setup.

lAKD Parameter and Command Reference Guide. This guide provides documentation for the param-

eters and commands used to program the AKD.

lAKD Accessories Manual. This manual includes technical data and dimensional drawings of acces-

sories such as cables, brake resistors, and mains supplies.

lAKD CANopen Communication. This manual includes setup information for the CAN interface and

describes the CANopen profile.

1.2 Target Group

This manual addresses personnel with the following qualifications:

lInstallation: only by electrically qualified personnel.

lSetup : only by qualified personnel with extensive knowledge of electrical engineering

and drive technology

lProgramming:Software developers, project-planners

The qualified personnel must know and observe the following standards:

lISO 12100, IEC 60364 and IEC 60664

lNational accident prevention regulations

During operation there are deadly hazards, with the possibility of death, severe

injury or material damage. The operator must ensure that the safety instructions

in this manual are followed. The operator must ensure that all personnel respon-

sible for working with the servo drive have read and understand the manual.

2.1 Safety Instructions

During operation there are deadly hazards, with the possibility of death, severe

injury or material damage. Do not open or touch the equipment during operation.

Keep all covers and cabinet doors closed during operation. Touching the equip-

ment is allowed during installation and commissioning for properly qualified per-

sons only.

lDuring operation, drives may have uncovered live components, depend-

ing on their level of enclosure protection.

lControl and power connections may be live, even though the motor is not

rotating.

lDrives may have hot surfaces during operation. Heat sink can reach tem-

peratures above 80°C.

Electronic equipment is basically not failure-proof. The user is responsible for

ensuring that, in the event of a failure of the servo amplifier, the drive is set to a

state that is safe for both machinery and personnel, for instance with the aid of a

mechanical brake.

Drives with servo amplifiers and EtherCAT expansion cards are remote-con-

trolled machines. They can start to move at any time without previous warning.

Take appropriate measures to ensure that the operating and service personnel

is aware of this danger.

Implement appropriate protective measures to ensure that any unintended start-

up of the machines cannot result in dangerous situations for personnel or

machinery. Software limit-switches are not a substitute for the hardware limit-

switches in the machine.

Install the drive as described in the Installation Manual. The wiring for the

analog setpoint input and the positioning interface, as shown in the wiring dia-

gram in the Installation Manual, is not required. Never break any of the electrical

connections to the drive while it is live. This action can result in destruction of

the electronics

Do not connect the Ethernet line for the PC with the set up software to the Ether-

CAT interface X5/X6. The set up Ethernet cable must be connected to the serv-

ice interface on X11
