1.1 Product Safety

1.1.1 You should pay attention to this

This section helps you to recognize and avoid dangers to people and objects.

Specialist staff required!

The devices are intended for industrial applications. Machine builders must employ qualified

personnel. Qualified personnel are people who have been trained to transport, install, com-

mission and operate electrical drives.

Transport, storage, unpacking: only by personnel with knowledge of handling elec-

trostatically sensitive components.

Mechanical installation: only by personnel with mechanical expertise.

Electrical installation: only by personnel with expertise in electrical engineering.

Basic tests / setup: only by personnel with expertise in electrical engineering and drive

technology.

The qualified personnel must know and observe ISO 12100 / IEC 60364 / IEC 60664 and

national accident prevention regulations.

Read the documentation!

Read the available documentation before installation and commissioning. Improper handling

of the devices can cause harm to people or damage to property. The operator of systems

using the drive system must ensure that all personnel who work with the drive read and under-

stand the manual before using the drive.

Check Hardware Revision!

Check the Hardware Revision Number of the product (see product label). This number is the

link between your product and the manual. The product Hardware Revision Number must

match the Hardware Revision Number on the cover page of the manual.

Pay attention to the technical data!

Adhere to the technical data and the specifications on connection conditions. If permissible

voltage values or current values are exceeded, the devices can be damaged. Unsuitable

motor or wrong wiring will damage the system components. Check the combination of drive

and motor. Compare the rated voltage and current of the units.

Perform a risk assessment!

The manufacturer of the machine must generate a risk assessment for the machine, and take

appropriate measures to ensure that unforeseen movements cannot cause injury or damage

to any person or property. Additional requirements on specialist staff may also result from the

risk assessment.

Automatic Restart!

The drive might restart automatically after power on, voltage dip or interruption of the supply

voltage, depending on the parameter setting.

Risk of death or serious injury for humans working in the machine.

If the parameter DRV.ENDEFAULT for one AKD-N is set to 1, then place a warning sign to

the machine (Warning: Automatic Restart at Power On) and ensure, that power on is not pos-

sible, while humans are in a dangerous zone of the machine. In case of using an under-

voltage protection device, you must observe EN 60204-1:2006 chapter 7.5 .

4 Kollmorgen | kdn.kollmorgen.com | March 2021

Observe electrostatically sensitive components!

The devices contain electrostatically sensitive components which may be damaged by incor-

rect handling. Electrostatically discharge your body before touching the device. Avoid con-

tact with highly insulating materials (artificial fabrics, plastic film etc.). Place the device on a

conductive surface.

Hot surface!

Drives may have hot surfaces during operation. The housing can reach temperatures above

80°C. Risk of minor burns! Measure the temperature, and wait until the housing has cooled

down below 40 °C before touching it.

Earthing!

It is vital that you ensure that the drive is safely earthed to the PE (protective earth) busbar in

the switch cabinet. Risk of electric shock. Without low-resistance earthing no personal pro-

tection can be guaranteed.

Leakage Current!

Since the leakage current to PE is more than 3.5 mA, in compliance with IEC61800-5-1 the

PE connection must either be doubled or a connecting cable with a cross-section >10 mm²

must be used. Deviating measures according to regional standards might be possible.

Residual current protective or monitoring devices!

AKD-C with AKD-N can cause a d.c. current in the protective earthing conductor. Where a

residual current-operated protective (RCD) or monitoring (RCM) device is used for protection

in case of direct or indirect contact, only an RCD or RCM of Type B is allowed on the supply

side of AKD-C.

Lethal voltages!

The equipment produces high electric voltages up to 900V. Do not open or touch the equip-

ment during operation. Keep all covers closed.

During operation, AKD-C may have uncovered live sections, according to their level of

enclosure protection.

Lethal danger exists at live parts of the device. Built-in protection measures such as insu-

lation or shielding may not be removed. Work on the electrical installation may only be per-

formed by trained and qualified personnel, in compliance with the regulations for safety at

work, and only with switched off mains supply, and secured against restart.

Never undo any electrical connections to the AKD-C while it is live. There is a danger of elec-

trical arcing with damage to contacts and personal injury. Wait at least 7 minutes after dis-

connecting the product from the supply voltages (mains supply and 24V supply) before

touching potentially live sections of the equipment (such as contacts) or removing any con-

nections.

Functional Safety

The STO safety implementation on the AKD is certified. The assessment of the safety func-

tions according to EN13849 or EN 62061 must finally be done by the user. Serious injury

could result when a suspended load is not properly blocked. Functional safety requires and

additional, external mechanical brake, operated by a safety controller.

Never modify the drive!

It is not allowed to modify the drive hardware without permission by the manufacturer. Open-

ing the housing causes loss of warranty.

AKD-C/N Safety Notes | 1 English

1.1.2 Use as Directed AKD-C

The AKD-C series power supplies are exclusively intended for operating AKD-N series

drives within a decentralized drive system.

AKD-C are components that are built into electrical plants or machines and can only be oper-

ated as integral components of these plants or machines. The manufacturer of the machine

must generate a risk assessment for the machine.

When the devices are built into machines or plant, the drive must not be used until it has been

established that the machine or plant fulfills the requirements of the regional directives.

Kollmorgen Decentral drive system

AKD-C series power supply must only be operated in a motion system with components from

Kollmorgen. Required additional Kollmorgen components are the "near servo drives" AKD-N,

hybrid cables, motor power and feedback cables, servomotors.

Assembling

AKD-C devices must only be operated in environments suitable for the ambient conditions

defined in the Installation Manual. Observe the information given in the Decentralized Sys-

tem Project Guide.

Wiring

Use only Kollmorgen CCNxN1 series of hybrid cables for connecting AKD-N and AKD-C

devices.

Power supply

AKD-C must be powered from a 3 phase industrial supply network

(not more than 42 kA symmetrical rated current at 400 V and 480 V).

For the cases of group installations and of DC powered drives

AKD has not been evaluated by Kollmorgen, UL, or TÜV for group installations nor are rat-

ings defined for DC input voltage.

Group installations must be reviewed and evaluated by the user for branch circuit protection*,

wire size, wire voltage rating, fuse protection, system dielectric requirements, overvoltage

and input** current rating.

In case of DC supplied drives the built-in EMC filter will not work. The user is responsible to

keep the conducted emissions and the immunity of the drive within the required noise levels.

* Special care must be taken in branch circuit design with mixed rating drives to avoid the

smaller drives becoming the effective ‘fuse’ rather than the circuit protective fuse.

** The power supply system design must ensure inrush current protection by limiting input cur-

rent during power up. DC supply polarity must be properly wired. Improper polarity of DC

power will damage the drive and void warranty.

Auxiliary voltage supply, Standby power

Standby power for the drive strings must only be used for supplying the AKD-N electronics.

24 VDC supply unit must accord to PELV (EN 60204-1) requirements.

Safe torque off

Review the section "Use as Directed" in the STO chapter in the Installation Manual before

using this safety function (SIL2, PLd, category 3 according to ISO 13849).
