AKD-C/N Safety Notes | 1 English
1.1.4 Use as Directed AKD-N
The AKD-N family of drives is exclusively intended for driving suitable synchronous ser-
vomotors with closed-loop control of torque, speed, and/or position.
Drives 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 drives 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 Decentralized Drive System
AKD-N series drives must only be operated in a motion system with components from Koll-
morgen. Required additional Kollmorgen components are the intelligent power supply AKD-
C, hybrid cables, motor power and feedback cables, servomotors.
Assembling
AKD-N drives must only be operated in machines suitable for the ambient conditions defined
in the Installation Manual. Optional finned heat sink may be necessary to keep the drive
flange temperature below 85 °C and enable the axis to operate with maximum power.
Observe the information given in the Decentral System Project Guide.
Guide.
Wiring
Use only Kollmorgen CCNxN1 series of hybrid cables for connecting AKD-N and AKD-C
devices. For connecting AKD-N to MKD-C devices use MKC-HYB-z-AKN cable only.
Power supply
AKD-N series drives must be powered by AKD-C or MKD-C intelligent power supplies with
DC voltage from 55 VDC up to 800 VDC.
Motor voltage rating
The rated voltage of the motors must be at least as high as the DC bus link voltage divided by
√2 produced by the drive (U
nMotor
>=U
DC
/√2).
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).
The 24 VDC supply unit for local STO supply must accord to PELV (EN 60204-1) require-
ments.
1.1.5 Prohibited Use AKD-N
Other use than that described in chapter “Use as directed” is not intended and can lead to per-
sonnel injuries and equipment damage.
The device may not be used
with a machine that does not comply with appropriate national directives or standards,
for driving elevators,
in ships or offshore applications,
in applications with continuous, operational short circuits to the motor power contacts.
The use of the device in the following environments is also prohibited:
potentially explosive areas,
environments with corrosive and/or electrically conductive acids, alkaline solutions, oils,
vapors, dusts.
Wiring the system with hybrid cables from other manufacturers than Kollmorgen is not
allowed. Changing Kollmorgen cables or connectors is not allowed.
